A Step-by-Step Guide to the Data Analysis Process

Data analysis follows to a strict, sequential method, just like any scientific profession. Each step calls for a unique set of abilities and knowledge. But it’s crucial to comprehend the process as a whole in order to gain pertinent knowledge. A solid foundation is essential for developing results that endure examination.
Several processes in the data analysis process enable you to methodically extract insights from data. An outline of the steps involved in data analysis is given as follows:

Step one: Defining the question

Identifying your purpose is the first stage in any analysis of data procedure. This is sometimes known as the “problem statement” in the context of data analytics.

Creating a hypothesis and planning how to test it is a necessary step in defining your purpose. Start by identifying what business issue you’re attempting to resolve. Although it can seem simple, it can be more difficult than it appears. Senior management of your company, for instance, can raise the question, “Why are we losing customers?” However, it’s possible that this doesn’t address the root of the issue. A data analyst’s responsibility is to have a thorough understanding of the business and its objectives so they can define problems appropriately.

2. Step two: Collecting the data

Once your goal has been determined, you must come up with a plan for gathering and combining the necessary data. Choosing the data you require is a crucial component of this. These could be qualitative (descriptive) data, like customer reviews, or quantitative (numeric) data, like sales figures. First-party data, second-party data, and third-party data are the three categories into which all data falls. Explore each one separately.

What is first-party data?

Data that you or your business directly obtained from clients are known as first-party data. It could be information from your company’s customer relationship management (CRM) system or transactional monitoring data. No matter where it comes from, first-party data is typically well-structured and arranged. Customer surveys, focus groups, interviews, and direct observation are possible additional sources of first-party data.

Second-party data: what is it?
You might want to secure a secondary data source to enhance your study. The first-party data of other organisations is referred to as second-party data. This might be accessible directly from the business or via a closed market. While second-party data will often be less relevant than first-party data, they also tend to be highly dependable, and their main advantage is that they are typically structured. Website, app, or social media activity, such as online purchase history or shipment information, are examples of second-party data.

Third-party data: what is it?
Data that has been gathered and combined from many sources by a third-party organisation is referred to as third-party data. Third-party data frequently (though not always) includes a sizable number of unstructured data pieces (big data). a lot of organisations

3. Data cleansing is the third step.

The next step after gathering your data is to prepare it for analysis. Making ensuring you are working with high-quality data requires cleaning, or “scrubbing,” the data. Important data cleaning duties include:

Getting rid of significant errors, duplication, and outliers—all issues that always arise when combining data from several sources.
removing unnecessary data points—extracting observations that are extraneous to your study.
Adding structure to your data—general “housekeeping,” such as correcting spelling mistakes or layout flaws, which will make it easier for you to map and manipulate your data.
Filling in significant gaps: As you’re organising, you can realise that crucial facts are missing. You can start filling holes once you’ve found them.

4. Step four: Analyzing the data

You’ve finally cleared up your info. The fun part will now be analyzing it. Your goal will have a significant impact on the type of data analysis you perform.
What insights you hope to get will determine how to proceed. All methods of data analysis can be categorised broadly into one of the following four groups.

Descriptive analysis

What has previously occurred is identified using descriptive analysis. It is a typical first action that businesses take before moving forward with deeper explorations.

Diagnostic analysis

The goal of diagnostic analytics is to find out why something happened. In the same way that a doctor utilizes a patient’s symptoms to diagnose a sickness, it is literally the diagnosis of an issue.

Predictive analysis

Based on historical data, predictive analysis enables you to pinpoint potential trends for the future. Predictive analysis is frequently used in business to, for instance, project future growth. But it goes further than that.

Prescriptive analysis

With prescriptive analysis, you can suggest changes for the future. The process’s final step in the analytics section is this. It is also the most difficult. This is due to the fact that it includes elements from every other analysis we’ve discussed.

5. Step five: Sharing your findings

Sharing these insights with the general public (or at the very least with the stakeholders in your organisation) is the last step of the data analytics process. This involves more than just disclosing the unprocessed results of your work; it includes interpreting the findings and communicating them in a way that is understandable to a variety of audiences. Since you’ll be presenting information to decision-makers quite frequently, it’s important that the conclusions you draw be entirely open and unambiguous. Because of this, reports, dashboards, and interactive visualisations are frequently used by data analysts to back up their conclusions.

{85, 90, 78, 92, 88, 95, 82, 86, 91, 89}.

To find the median, we first arrange the values in ascending order:
78, 82, 85, 86, 88, 89, 90, 91, 92, 95. Since there are 10 observations, the median is the middle value, which is the 5th value, 88. Therefore, the median score is 88.

Mode:

Mode:
Take a look at the dataset below, which shows the number of pets that each home in a neighbourhood owns
{0, 1, 2, 2, 3, 1, 4, 0, 2, 1}.
To find the mode, we identify the value(s) that occur most frequently. In this case, both 1 and 2 occur three times, which makes them the modes of the dataset.
Therefore, the modes for this dataset are 1 and 2.

Measures of Variability

Let’s use a sample dataset to describe metrics of variability:
Look at the dataset below, which shows the ages of 10 people: {20, 25, 22, 28, 30, 21, 24, 27, 26, 23}.

Variance:
Standard Deviation

Add Your Heading Text Here

VARANCE

Calculate the mean:

(165 + 170 + 172 + 168 + 175 + 169 + 171 + 174) / 8 = 1374 / 8 = 171.75.

1.Subtract the mean from each value and square the differences:

(165 – 171.75)^2, (170 – 171.75)^2, (172 – 171.75)^2, (168 – 171.75)^2, (175 – 171.75)^2, (169 – 171.75)^2, (171 – 171.75)^2, (174 – 171.75)^2.

2.The squared differences are: (39.0625, 3.0625, 0.5625, 12.5625, 14.0625, 5.0625, 0.5625, 6.0625).

3.Calculate the sum of these squared differences:

39.0625 + 3.0625 + 0.5625 + 12.5625 + 14.0625 + 5.0625 + 0.5625 + 6.0625 = 81.4375.

4.Divide the sum by the total number of observations minus 1 (8 – 1 = 7)

5.to get the sample variance:

81.4375 / 7 = 11.6339285714.

Standard deviation

1.Calculate the variance (as explained in the previous response): Variance = 11.6339 square centimeters.

2.Take the square root of the variance to obtain the standard deviation: Square root of 11.6339 ≈ 3.4112.

Therefore, the standard deviation of the dataset is approximately 3.4112 centimeters.

Standard deviation measures the dispersion or spread of data points around the mean. In this example, the standard deviation indicates the average distance between each height

Measures of Shape and Distribution:

Measures of Shape and Distribution:

Shape and distribution metrics give information about the distributional properties of a dataset. They aid in understanding the data’s uniformity, specific form, and tail behavior. Here are some typical metrics for distribution and shape:

Skewness:
Kurtosis:

Skewness:

Positive Skewness:

Consider a dataset with the following values for the income levels of a population’s members (in thousands of dollars): 20, 25, 30, 35, 40, 45, 50, and 150.
Positive skewness is indicated by the distribution’s right-side longer tail.
The majority of people’s incomes are concentrated in the lower range, whereas only a small number of people have much higher wages.
In this positively skewed distribution, the mean income is higher than the median income.

Negative Skewness:

Let’s consider a dataset representing the waiting times (in minutes) at a doctor’s office:
{50, 40, 30, 20, 15, 10, 5, 1}.
The distribution has a longer tail on the left side, indicating negative skewness.
Most individuals experience shorter waiting times, with a few outliers experiencing longer waiting times.
The mean waiting time is lower than the median waiting time in this negatively skewed distribution.

Skewness of Zero:

Consider a dataset representing the heights (in centimeters) of individuals in a sample:

{160, 165, 170, 175, 180, 185}.

1.The distribution is symmetric, with no significant imbalance in the tails.

2.The data is equally distributed around the mean, and there are no substantial skewness effects.

These examples illustrate the concept of skewness in different datasets. Positive skewness indicates a longer or fatter tail on the right side, negative skewness indicates a longer or fatter tail on the left side, and skewness of zero suggests a symmetric distribution.

Kurtosis

Kurtosis

*Consider a dataset representing the returns (in percentages) of a stock over a certain period: {-3, 2, 1, -1, 0, 1, 4, 2}.

To calculate the kurtosis:

Calculate the mean:

(-3 + 2 + 1 + -1 + 0 + 1 + 4 + 2) / 8 = 6 / 8 = 0.75.

Calculate the variance:

Variance = [(1/8) * ((-3 – 0.75)^2 + (2 – 0.75)^2 + (1 – 0.75)^2 + (-1 – 0.75)^2 + (0 – 0.75)^2 + (1 – 0.75)^2 + (4 – 0.75)^2 + (2 – 0.75)^2)] ≈ 4.875.

Calculate the fourth moment:

Fourth Moment = [(1/8) * ((-3 – 0.75)^4 + (2 – 0.75)^4 + (1 – 0.75)^4 + (-1 – 0.75)^4 + (0 – 0.75)^4 + (1 – 0.75)^4 + (4 – 0.75)^4 + (2 – 0.75)^4)] ≈ 33.7969.

Calculate the kurtosis:

Kurtosis = (Fourth Moment / Variance^2) – 3 ≈ (33.7969 / (4.875^2)) – 3 ≈ 0.9796.

Therefore, the kurtosis of the dataset is approximately 0.9796.

Kurtosis measures the peakedness or flatness of a distribution compared to a normal distribution. In this example, the positive kurtosis value suggests that the distribution has a sharper peak and heavier tails compared to a normal distribution. It indicates a higher likelihood of extreme returns or outliers in the dataset.

Percentile :

Percentile :

75th percentile is the value below which 75% of the data falls. This means that 75% of the data values in the dataset are less than or equal to the 75th

Range

Range, an easy measure of variability, shows the difference between a dataset’s highest and minimum values. It gives an elementary understanding of how the data are distributed.

Use these steps to determine a dataset’s range:

The dataset should be sorted ascending.

Take the least value and subtract it from the maximum value.

Range

For example, consider the following dataset representing the heights (in centimeters) of a group of individuals: {160, 165, 170, 175, 180, 185}.

To calculate the range:

Sort the dataset in ascending order: {160, 165, 170, 175, 180, 185}.

Subtract the minimum value (160) from the maximum value (185):

Range = 185 – 160 = 25.

Therefore, the range of the dataset is 25 centimeters. It indicates that there is a 25-centimeter difference between the tallest and shortest individuals in the group.

While the range provides a simple measure of variability, it has limitations as it only considers the extremes of the dataset. It does not provide information about the distribution or variability within the dataset. Other measures, such as variance and standard deviation, offer more comprehensive insights into the spread of data.

Frequency Distribution

Consider the following dataset representing the scores of students in a class: {75, 80, 65, 70, 85, 90, 75, 80, 75, 85, 80, 70, 75}.

To create a frequency distribution table:

Sort the dataset in ascending order: {65, 70, 70, 75, 75, 75, 75, 80, 80, 80, 85, 85, 90}.

Identify the unique values in the dataset and determine their frequencies (number of occurrences).

Frequency Distribution

Count how many times each value appears in the dataset.

Value | Frequency

65 | 1

70 | 2

75 | 4

80 | 3

85 | 2

90 | 1

This frequency distribution table shows the unique values in the dataset and their corresponding frequencies. For example, the value 75 appears four times, while the values 65 and 90 appear only once.

Frequency distribution tables provide a summary of the distribution of values in a dataset. They help identify the most common values and provide an overview of the frequency or occurrence of different values. This information can be useful for further analysis and understanding of the dataset.

Inferential Statistics

Inferential statistics is an area of statistics that deals with making inferences or conclusions about a wider population based on sample data. It helps investigators in generalizing from small data sets and making predictions. Here is an illustration of the idea of inferential statistics:
Let’s imagine a business wishes to gauge how satisfied its staff members are with their jobs. There are 10,000 people working for the company. They choose to get information from a randomly selected sample of 500 employees rather than conducting time-consuming and unrealistic surveys of every employee.

Sampling:

Out of a total workforce of 10,000 employees, 500 are chosen at random by the corporation. By doing this, bias in the sample is diminished and every employee has an equal chance of getting chosen.

Data collection:

A job satisfaction survey is given to the 500 employees that were chosen. The survey includes inquiries about respondents’ general job satisfaction, work-life balance, pay, chances for career advancement, and other pertinent issues.

Descriptive Statistics

In order to summarise the sample data, descriptive statistics are utilised. For the 100 cars in the sample, the manufacturer computes the mean, median, and standard deviation of the fuel efficiency figures.

Inferential Statistics:

Based on the sample data, inferential statistics are used to make inferences about the typical fuel efficiency of the 1,000 cars.

Confidence Intervals:

To determine the range within which the actual population mean fuel economy lies, the manufacturer calculates a confidence interval, such as a 95% confidence interval. Suppose they discover that the sample’s average fuel economy is 50 MPG, with a 95% confidence range ranging from 48 MPG to 52 MPG. Since the genuine population mean fuel efficiency falls within this range, they may be 95% confident in this.

Example

Let’s use an example to calculate inferential statistics. Let’s say we’ve gathered the MPG (miles per gallon) information for a sample of 50 cars. These are the data:

45, 42, 50, 48, 43, 47, 52, 55, 49, 51, 46, 44, 53, 47, 49, 48, 50, 45, 46, 52, 50, 48, 45, 47, 51, 49, 52, 54, 46, 47, 49, 48, 50, 45, 43, 51, 48, 50, 47, 49, 46, 52, 49, 44, 47, 48, 51, 50, 48, 46, 49, 51.

Step 1: Descriptive Statistics
Let’s figure out the sample’s mean, median, and standard deviation.

The sum of all the values divided by the total number of values is the mean.
Sum = 2,417
Mean = Sum / Number of values = 2,417 / 50 = 48.34 MPG

Median: Arrange the values in ascending order and find the middle value:
42, 43, 43, 44, 45, 45, 45, 46, 46, 46, 46, 47, 47, 47, 47, 47, 48, 48, 48, 48,
48, 48, 48, 49, 49, 49, 49, 49, 49, 49, 50, 50, 50, 50, 50, 51, 51, 51, 51, 52,
52, 52, 52, 53, 54, 55
Median = 48 MPG

Standard Deviation:
Calculate the standard deviations for each value:
Value – Mean equals deviation
We determine the deviations using the example data in the manner shown below:

(-3.34), (-6.34), 1.66, (-0.34), (-5.34), (-1.34), 3.66, 6.66, 0.66, 2.66,
(-2.34), (-4.34), 4.66, (-1.34), 0.66, (-0.34), 1.66, (-3.34), (-2.34), 3.66,
1.66, (-0.34), (-3.34), (-1.34), 2.66, 0.66, 3.66, 5.66, (-2.34), (-1.34),
0.66, (-0.34), 1.66, (-3.34), (-5.34), 2.66, (-0.34), 1.66, (-1.34), 0.66,
(-2.34), 3.66, 0.66, (-4.34), (-1.34), 0.66, (-0.34), 2.66, 1.66, (-0.34),
(-2.34), 0.66, 2.66.
Square each deviation:
Squared Deviation = Deviation^2
Squaring each deviation, we have:

11.1556, 40.1956, 2.7556, 0.1156, 28.5156, 1.7956, 13.4356, 44.3556,
0.4356, 7.0756, 5.4756, 18.8356, 21.5956, 1.7956, 0.4356, 0.1156, 2.7556,
11.1556, 5.4756, 13.4356, 2.7556, 0.1156, 11.1556, 1.7956, 7.0756, 0.4356,
13.4356, 32.1156, 5.4756, 1.7956, 0.4356, 2.7556, 11.1556, 28.5156, 0.1156,
2.7556, 1.7956, 0.4356, 0.1156, 5.4756, 13.4356, 0.4356, 18.8356, 1.7956,
0.4356, 0.1156, 7.0756, 2.7556, 0.1156, 5.4756, 0.4356, 7.0756.

Calculate the sum of squared deviations:
Sum of Squared Deviations = Σ(Squared Deviation)
Adding up the squared deviations, we get:
Sum of Squared Deviations = 581.92

Divide the sum of squared deviations by the number of values:
Variance = Sum of Squared Deviations /

Why communication is a very important skill in Data Analytics

Data Analytics usually find insight and patterns from data and these outcomes are hard and complex to understand for non-It persons therefore It is essential for you to have the capabilities and skills to interpret data and deliver well-contained stories. As a data analyst, writing, presenting, and communicating, in general, is essential.

Besides having skills like logical and problem-solving skills communication is a fundamental skill for data Analytics.

There are several types of communication skills that Data analytics have to master we will discuss them in this article.

Working and collaborating with team members and stakeholders

You’ll spend a lot of time alone at a computer as a data analyst or data scientist studying datasets and algorithms. However, you’ll also certainly do a lot of teamwork. Working as a team with other analysts or scientists is typical, particularly when working on significant projects or managing enormous datasets. In addition, you’ll regularly collaborate with groups of individuals and stakeholders who don’t use data. To work well with others, it’s critical to have strong communication skills.

Types of Skills Required in Data Analytics

Some of the most recommendable Communication Skills Data Analytics must-have.

Story Telling :

Storytelling skills are especially critical in roles that involve marketing to an audience or sharing information with others. A good story can persuade, inform or entertain others depending on what kind of story you tell.

The most important aspect of delivering data insights is storytelling. You will certainly employ storytelling tactics to deliver your presentations if you are an effective presenter. Additionally, while data analysis can be quite difficult, a strong plot will make the results useful and appealing to business users.

Presenting Skills:

Presentation skills help create innovative ideas when students come up with creative and interesting slides to illustrate their talk. The use of presentation aids makes for a much more interesting talk, and the creation of such aids can help develop students’ confidence.

Data Visualization Skills:

Data visualization is the representation of information and data using visuals such as graphs, charts, maps, and more. Those who use data visualization in their work use tools to present data to non-technical audiences in a form of storytelling that helps businesses make data-driven decisions.

Critical Thinking :

Critical thinking is the most demanded skill it is the ability to analyze facts and form a judgment. It is a form of emotional intelligence. Someone with critical thinking skills can think clearly and rationally when the situation demands it.
It allows them to perform problem-solving and decision-making more effectively.

Listening Skills:

Listening is the ability to accurately receive and interpret messages in the communication process. • Listening is key to all effective communication, without. the ability to listen effectively messages are easily misunderstood. • Listening is one of the most important skills you can have.

Keeping Audiences Engaged with Data Presentation

There are certain point keep in mind before presenting your Data.

Why they should Listen:

If there isn’t a clear interest on behalf of your audience, you must convince them to pay attention. Because some audiences don’t interact openly, this can be awkward. The response? Give them a reason to care.

For example, If you’re giving a talk about sales and marketing, remind the audience about a few salespeople who overcome extraordinary obstacles and succeeded.

Stick to your Topic of discussion;

Try to be specific and tell examples and stories to elaborate your finding and understand your audience requirement and what they want from you

Make sure there is ‘flow’ in your presentation.

If your presentation is compelling and audience members are hanging on your every word, then you’re in a state of ‘flow’.

Story Telling

There should be a few stories thrown throughout every presentation. The moment you say, “Let me tell you a story about…”, people start to pay attention because they are programmed to do so. However, be sure that the stories support the points you’re making.

Let your audience talk

Inviting audience members to speak will make them feel valued. In addition, it allows you to mentally rest for a little while.

choosing between a career in data science and analytics

1. Take into account your background.

To assist firms make more strategic decisions, data analysts analyse enormous data sets to find trends, build charts, and produce visual presentations. Analysts generally seek undergraduate STEM degrees, and perhaps even graduate degrees in analytics or a similar discipline, to ensure that their education is in line with these objectives. Additionally, they look for candidates with background in science, math, programming, databases, modelling, and predictive analytics.

Data scientists need to have “more of a foundation in computer science,” he adds, adding that they are “far more technical and mathematical [than data analysts].”

It’s crucial to study these educational prerequisites while deciding which job route is best for you. You will probably have the educational and professional background to pursue either path if you have already decided to invest in your career with an advanced degree. On the other hand, since employers are more likely to consider candidates without a master’s degree for these positions, you might be more inclined to stick with a data analytics role if you’re still debating whether returning to school is the right choice for you.

Consider your interests.

Data scientists need to have “more of a foundation in computer science,” he adds, adding that they are “far more technical and mathematical [than data analysts].”

It’s crucial to study these educational prerequisites while deciding which job route is best for you. You will probably have the educational and professional credentials to pursue either option if you have previously decided to invest in your career with an advanced degree. On the other hand, since companies are more likely to consider people without a master’s degree for these positions, you could be more motivated to continue with a data analytics role if you’re still debating whether returning to school is the correct choice for you.

3. Take into account the salary and career path you want.

Earning potential for data analysts is from $83,750 to $142,500. However, because these professionals mostly work with databases, they can raise their wages by learning new programming languages like R and Python.

Data analysts with more than ten years of experience, however, frequently take advantage of their earning potential and move on to other positions, according to PayScale. Following the completion of an advanced degree, two common career changes, according to Blake Angove, director of technology services at IT staffing firm LaSalle Network, include moving into a developer or data scientist position.

Data scientists are regarded as being more senior than data analysts because they frequently possess advanced skills, a doctorate degree, and more experience. As a result, they frequently receive more pay for their services. RHT estimates that the average annual salary for data scientists is between $105,750 and $180,250.
