The 4 Types of Data Analysis and their difference

type of analytics

Businesses and organisations that continuously learn and adapt are the most successful. No matter what sector you work in, it’s critical to be aware of the recent past, the current state of affairs, and potential future developments. So how do businesses accomplish that?

Data analytics holds the solution. Most businesses constantly gather data, yet this data is meaningless in its unprocessed state. What you do with the data is what really matters. Data analytics is the act of examining raw data to identify patterns, trends, and insights that might provide valuable information about a certain business domain. Following that, informed judgments based on data are made using these insights.

AI and sophisticated analytics have gained popularity in recent years. There are a lot of blogs out there that discuss the benefits of employing sophisticated analytics in your company.

It is tempting to go right in and try to get advanced analytics straight immediately given the amount of value that they may provide. But these insights cannot be attained without the right foundations. What is the first step to obtaining these insightful data, then?

Advanced analytics success and the use of AI can be ensured by comprehending the analytics development and getting started in the proper spot.

56 percent of respondents claimed data analytics resulted in “faster, more effective decision-making” at their firms, according to MicroStrategy’s The Global State of Enterprise Analytics survey (pdf). Other advantages mentioned include:

  • increased productivity and efficiency (64 percent)
  • better financial results (51 percent)
  • Finding and generating new sources of revenue for products and services (46 percent)
  • enhanced client acquisition and retention (46 percent)
  • enhanced client experiences (44 percent)
  • advantage over rivals (43 percent)


Any business professional who takes judgments must have a solid understanding of data analytics. Data access is easier to come by than ever. You may overlook significant possibilities or warning signs if you design strategies and make decisions without taking the facts into account.

Skills in data analytics can be useful for the following professions:

1. Descriptive Analytics

The foundation for all other types of analytics is descriptive analytics, which is the most basic type. It enables you to quickly summarise what occurred or is happening by drawing trends from the raw data.

What happened is answered by descriptive analytics.

Consider the scenario where you are studying the statistics for your business and discover that sales of one of your goods, a video game console, are increasing at a seasonal rate. Here, descriptive analytics can inform you, “Sales of this video game system increase each year in early December, early November, and October.”

Charts, graphs, and maps may clearly and understandably display data patterns, as well as dips and spikes, making data visualization a good choice for expressing descriptive analysis.

The following are some typical techniques in descriptive analytics:

  1. Data aggregation: Getting an overview of the data by grouping it according to specific criteria, such as time periods, locations, or categories.
  2. Summary Statistics: Calculating measures such as mean, median, mode, standard deviation, range, and percentiles to understand the central tendency, dispersion, and distribution of the data.
  3. Data Visualization: Representing data using graphs, charts, and other visual formats to communicate patterns, trends, and relationships in a more intuitive way. Examples include bar charts, line graphs, scatter plots, and heat maps.
  4. Data Exploration: Conduct exploratory data analysis (EDA) techniques to examine data characteristics, identify outliers, detect missing values, and gain initial insights into the dataset.
  5. Data Profiling: Profiling the data to understand its structure, quality, and completeness. This involves examining data types, assessing data integrity, and identifying any data issues or anomalies.
  6. Segmentation: Dividing data into meaningful groups or segments based on specific attributes or characteristics. This can help identify different patterns and behaviors within the dataset.
  7. Time Series Analysis: Analyzing data that is collected over time to uncover patterns, seasonality, and trends. Time series analysis techniques include moving averages, trend analysis, and forecasting.

2. Diagnostic Analytics

The following logical question, “Why did this happen?” is answered by diagnostic analytics.

This sort of analysis goes a step further by comparing current trends or movements, finding relationships between variables, and, when possible, establishing causal linkages.

Using the previous example, you might look at the demographics of video game console users and discover that they range in age from eight to 18 years old. The average age of the patrons, however, is between 35 and 55. Data from customer surveys that have been analysed show that buying a video game console as a present for kids is one of the main reasons people do so. The increase in sales throughout the fall and early winter may be attributed to the gift-giving holidays.

Using diagnostic analytics to identify

Here are some key aspects of diagnostic analytics:

  1. Root Cause Analysis: Identifying the root causes or factors that led to a particular event or outcome. This involves investigating correlations, dependencies, and relationships within the data to determine the underlying reasons.
  2. Comparative Analysis: Comparing different datasets or segments to understand variations and differences in performance. This could involve comparing the performance of different regions, time periods, customer segments, or product lines to identify patterns and anomalies.
  3. Hypothesis Testing: Formulating and testing hypotheses to validate or reject potential explanations for observed outcomes. Statistical tests and experiments are conducted to determine the significance of relationships and variables.
  4. Drill-Down Analysis: Analyzing data at a granular level by drilling down into specific dimensions or attributes. This allows for a detailed examination of the data to uncover insights that may be hidden at higher levels of aggregation.
  5. Cohort Analysis: Analyzing groups of individuals or entities that share common characteristics or experiences. Cohort analysis helps understand how different cohorts behave over time and can reveal important insights about customer behavior, product performance, or employee performance.
  6. Data Mining and Machine Learning: Utilizing advanced techniques such as data mining and machine learning algorithms to discover patterns, correlations, and predictive relationships in the data. These techniques can uncover hidden insights and provide a deeper understanding of the data.


3. Predictive Analytics

In order to predict future trends or events or to provide a response to the question “What might happen in the future,” predictive analytics is utilised.

You can accurately estimate what the future may hold for your firm by examining historical data along with current industry trends.

For instance, knowing that, over the previous ten years, sales of video game consoles have peaked in October, November, and the first few weeks of December each year gives you enough information to forecast that the same trend will continue in 2016. This is a logical prediction, supported by upward trends in the video game industry as a whole.

Making forecasts about the future might assist your company in developing plans based on probable outcomes.

Here are some key aspects of predictive analytics:

  1. Data Preparation: Preparing and cleansing the data to ensure its quality and suitability for analysis. This includes handling missing values, outliers, and transforming the data into a format suitable for modeling.
  2. Feature Selection and Engineering: Identifying the most relevant features or variables that are likely to have predictive power. This involves selecting informative variables and creating new derived features that may enhance the prediction models.
  3. Model Development: Building statistical or machine learning models based on the historical data. Common techniques used in predictive analytics include regression analysis, decision trees, random forests, support vector machines, neural networks, and ensemble methods.
  4. Training and Evaluation: Training the predictive models using a portion of the historical data and evaluating their performance on another portion of the data. This is done to assess how well the models generalize to unseen data and to select the best-performing model.
  5. Prediction and Forecasting: Applying the trained models to new or future data to generate predictions or forecasts. These predictions can be in the form of numerical values, classifications, or probabilities.
  6. Model Validation: Validating the predictive models by comparing the predicted outcomes with the actual outcomes observed in real-world scenarios. This helps assess the accuracy and reliability of the models.

4. Prescriptive Analytics

Prescriptive analytics finally provides a response to the query, “What should we do next?”

Prescriptive analytics recommends actionable takeaways after considering all potential aspects in a circumstance. Making decisions based on data can be extremely helpful when using this kind of analytics.

To complete the video game illustration: What should your team decide to do in light of the anticipated seasonality trend brought on by the holiday gift-giving season? Perhaps you decide to do an A/B test with two adverts, one geared toward customers and the other towards the product’s end-users (children) (their parents). The results of that experiment can help determine how best to further capitalise on the seasonal rise and its purported cause. Or, perhaps you decide to step up your marketing initiatives in September with messages centred around the holidays to try to prolong the boost.

Here are some key aspects of prescriptive analytics:

  1. Optimization Modeling: Developing mathematical or computational models that represent the problem domain and capture the relationships between variables, constraints, and objectives. These models aim to find the best solution that maximizes performance or minimizes costs based on predefined criteria.
  2. Constraint Analysis: Identifying and incorporating constraints and limitations into the optimization models. These constraints could be related to resource availability, capacity limits, regulatory requirements, or business rules that need to be adhered to.
  3. Scenario Analysis: Conducting “what-if” analysis by simulating different scenarios and evaluating their potential outcomes. This helps assess the impact of different decisions or actions on the desired outcomes and facilitates decision-making under various conditions.
  4. Decision Support Systems: Developing decision support tools or systems that can assist decision-makers in evaluating alternative courses of action and selecting the optimal solution. These systems often provide interactive interfaces and visualizations to aid in the decision-making process.
  5. Recommendation Engines: Implementing recommendation systems that utilize advanced algorithms to suggest the best actions or options based on user preferences, historical data, and real-time information. These engines are commonly used in personalized marketing, content recommendation, and product recommendation.
  6. Continuous Learning and Adaptation: Prescriptive analytics systems can be designed to continuously learn from new data, feedback, and outcomes. This allows for the refinement and adaptation of models and recommendations over time, leading to improved decision-making and performance optimization.
