What is data science role and responsibility of data scientist ?

what is data science ?

Data Science is “about using various techniques, algorithms to analyze large amounts of both structured or unstructured data, to extract useful data, thus applying them in various business domains.
Data science combines the scientific method, mathematics and statistics, specialized programming, advanced analytics, AI, and even storytelling to tell and understand the business insights buried in data.

Data preparation may involve cleaning, collecting, and manipulating it to be ready for specific types of processing. Analysis requires the development and use of algorithms, analytics and AI models.

How does data science work?

How does data science work?
Data science involves the proficiency of disciplines and areas of expertise to produce a comprehensive, complete and clean data set in raw data. Data scientists must be proficient in everything from data engineering, mathematics, statistics, advanced computing and visualization to effectively create exhaustive and clear data from a tangled medium of information and extract only the most important information that is most important. Help drive innovation and efficiency.

Data scientists also rely heavily on artificial intelligence, particularly machine learning and its subfields of deep learning, to build models and make predictions using algorithms and other techniques.

Data Science Tools

Learn python

The first and foremost step towards data science should be a programming language (ie Python). Python is the most common coding language, used by most data scientists, because of its simplicity, versatility, and being pre-equipped with powerful libraries (such as NumPy, SciPy, and Pandas) in data analysis and other aspects of data analysis. is useful. Science. Python is an open-source language and supports various libraries.


If Data Science is a language, then Statistics is basically grammar. Statistics is basically a method of analysis, interpretation of large data sets. When it comes to data analysis and insight gathering, statistics are just as remarkable as the wind for us. Statistics help us understand the hidden details from large datasets.

Data storage

This is one of the important and important steps in the field of data science. This skill includes knowledge of various tools for both importing data from local systems, such as CSV files, and scraping data from websites, using the Beautiful Soup Python library. Scraping can also be API-based. Data collection can be managed in Python with knowledge of the query language or ETL pipelines.

Data cleaning

This is the stage where most of the time is being spent as a data scientist. Data cleaning is suitable for obtaining, working and analyzing data from the raw form of the data by removing unwanted values, missing values, categorical values, outliers and incorrectly submitted records.

Data cleaning is very important as real world data is messy and achieving this with the help of various Python libraries (Pandas and NumPy) is really important for an aspiring data scientist.

Machine learning model

Machine learning models are the way by which you integrate machine learning models into an existing production environment to make practical business decisions based on data.

machine learning

Machine learning is the idea that computers can learn from examples and experience, without being explicitly programmed to do so. Instead of writing code, you feed data to the generic algorithm, and it builds logic based on the data given.

For example, one type of algorithm is a classification algorithm. It can keep data in different groups. Classification algorithms used to detect handwritten letters can also be used to classify emails into spam and non-spam.

Real world test

After deployment, the machine learning model should be tested and validated to check its effectiveness and accuracy. Testing is an important step in data science to keep the efficiency and effectiveness of ML models under control.

The various benefits of Data Science are as follows

1. It is in demand

Data science is in great demand. Potential job seekers have many opportunities. It is the fastest growing job on LinkedIn and is predicted to create 11.5 million jobs by 2026. This makes data science a highly employable job field.

2. Excess of posts

There are very few people who have the required skill-set to become a complete data scientist. This makes Data Science less saturated as compared to other IT sectors.

Hence, Data Science is a very abundant field and has a lot of opportunities. The field of data science is high in demand but low in supply for data scientists.

3. A Highly Paying Career

Data Science is one of the highest paying jobs. According to Glassdoor, data scientists earn an average of $116,100 per year. This makes data science a highly lucrative career option.

4. Data Science is Versatile

There are many applications of Data Science. It is widely used in healthcare, banking, consulting services and e-commerce industries. Data Science is a very versatile field. So you will get opportunity to work in different sectors.

5. Data Science Makes Data Better

Companies need skilled data scientists to process and analyze their data. They not only analyze the data but also improve its quality. Hence, Data Science is concerned with enriching the data and making it better for your company.

6. Data Scientists Are Highly Reputable

Data scientists allow companies to make better business decisions. Companies rely on data scientists and use their expertise to provide superior results to their customers. This gives data scientists an important position in the company.

7. No more boring tasks

Data Science has helped various industries to automate redundant tasks. Companies are using historical data to train machines to perform repetitive tasks. It has simplified the difficult tasks previously done by humans.

8. Makes Data Science Products Smart

Data Science involves the use of machine learning that has enabled industries to create better products specifically tailored to customer experiences.

Data scientist role and responsibilities

As a data scientist, you are often in charge of gaining insight and value from data to inform decisions and address challenging issues. A data scientist’s main duties include the following:

Data analysis and exploration

Large and complex datasets will be gathered, cleaned, and preprocessed by you. Exploratory data analysis (EDA) is used in this to comprehend the data, spot trends, and derive insights.

Machine learning and statistical modeling

To address business issues, you will create and use a variety of machine learning algorithms and statistical models. This entails choosing the right models, developing, testing, and fine-tuning their parameters.

Feature engineering

From the data, you will extract pertinent features that can help machine learning models perform better. In order to do this, variables must be transformed and combined, missing data must be handled, and instructive features must be chosen.

Data visualization

In order to convey complicated findings and insights to stakeholders, you will produce visualisations and reports. This includes presenting data in an understandable way by using tools like charts, graphs, and dashboards.

Predictive modeling and forecasting

In order to predict future trends and outcomes, you will create predictive models and forecast algorithms. In this process, models that can produce exact forecasts or predictions are trained using past data.

Experimental design and A/B testing

You’ll plan studies and run A/B tests to evaluate the effectiveness of various treatments or adjustments. Making data-driven judgments and evaluating the efficacy of tactics are both aided by this.
