Companies worldwide use data science to analyze the demands of their customers. Yes, you understood right today we are going to give you a complete guide to becoming Data Scientist.

Blogswrite makes sure to share the best and latest news on various niches. I believe that learning new skills, builds some awesome results in your work.

Before getting into the tips let’s start with some basics of data science.

What Is Data Science?

Data Science is the study of data using various techniques, and algorithms. This helps to analyze and extract meaningful and large amounts of datasets. Does not matter if the data is structured or unstructured it help in both cases. This obtained data can be further used according to the need of various business domains.

Data Science is most beneficial to understand certain questions and they are: –

  • What happened?
  • Why did it happen?
  • What will happen? and
  • What can be done with the results?

Isn’t this amazing…!!! By using one technique you can get answers to so many things that are beneficial for business growth.

Now, these points have answered the question of the need for Data Science. So, now you know the definition and its need in the current scenario. Now, let’s move on and understand the use of data science.

Use of Data Science

  1. Descriptive analysis

This helps to examine data to gain insights, especially on what happened or what is happening. The data visualization is done with the help of pie charts, bar graphs, line graphs, tables, etc.

For example,

There are a lot of online e-commerce sites that are offering sales these days. Like Myntra, Flipkart, and Amazon you can see the price difference due to the festive season.

  1. Diagnostic analysis

This analysis gives detailed information to understand why something happened. The analysis could be done using drill-down, data discovery, data mining, and correlations.

For example,

During October visiting Kedarnath will give you the best hotel deal. As this is an off-season there are fewer visitors as compared to June – July.

  1. Predictive analysis

A well-known analysis that is easily recognizable and observed by all. It is an analysis that uses historical data to accurately forecast what may occur in the future.

For example,

Pre-booking of flight tickets depends on the previous charges. The prediction of weather is also a good example of predictive analysis.

  1. Prescriptive analysis

This analysis takes the predictive data to another level. This analysis not only predicts what is going to happen but also suggests the best outcome. With the help of graphs, stimulation, and neural networks you can get the best suggestions.

For example,

Netflix shows the top 10 movies for a particular country depending on the number of clicks.

We hope you have enough idea about Data science, its benefits, and its uses. Stay tuned to the article to know the guide.

A complete guide to becoming Data Scientist. 

  1. Earn a data science degree.

This is the very basic thing a person should know if one wants to be a data scientist. The person must have a bachelor’s degree in

  • Data science,
  • Statistics, or computer science
  1. Sharpen the following relevant skills.

Well, if you want to be a good data scientist you need to polish your hard data skills. You can either go for online courses or can enroll in Bootcamp. We are suggesting you some of the skills that will help you: –

  • Programming languages 

Data scientists spend so much time using programming languages. Whether to sort through, analyze, and manage large chunks of data. Doing all these effectively there are some popular programming languages for data science:

  • Python
  • R
  • SQL
  • SAS


  • Data visualization

Being able to create various charts and graphs is the most relevant part of being a data scientist. These are the following tools that one should prepare you to do the work:

  • Tableau
  • PowerBI
  • Excel


  • Machine learning

For improving the quality of the data, a data scientist needs to learn machine learning. This will help in continuous growth and easy prediction of future datasets.

  • Big data

Some clients may ask to see whether you have some familiarity grappling with big data or not. There are software frameworks that are used to process big data. This also includes Hadoop and Apache Spark.

  • Communication

If you want to become a successful data scientist you need to have good communication. Whatever is your finding it won’t make any difference if you cannot communicate well. A Data Scientist should have the ability to share ideas and results verbally or in writing.

  1. Get an entry-level data analytics job

Becoming a data scientist, start with getting an entry-level job in the very first step. Start looking for jobs that work with large data. Get a job in a field like data analysis, business intelligence analyst, or statistician.

That is the best way where a person can start working to become a data scientist. This will help to expand your knowledge and skills to become successful at your job.

  1. Prepare for data science interviews.

You might be thinking that when you are already working then why do you need to prepare for interviews?

The answer is after gaining experience of a few years working in data analytics, you are ready to move. Working in the position of a data scientist is a highly technical job to do. You should have the knowledge to encounter both technical and behavioral questions.

We are suggesting to you some of the questions that you may face during the interview as a data scientist.

  • What are the pros and cons of a linear model?
  • What is a random forest?
  • How would you use SQL to find all duplicates in a data set?
  • Describe your experience with machine learning.
  • Give an example of a time you encountered a problem that you didn’t know how to solve. What did you do?

Popular F&Q related to Data Science

  1. What is the difference between data science and data analytics?

The simplest answer to this question is Data Analytics is a subset of Data Science. Data Science is the umbrella term for all aspects of data processing.

  1. What is the difference between data science and business analytics?

The key difference between both of them is the use of technology to get the results. Data Scientists work more strictly with data technology as compared to business analysts. Business analysts act as a bridge to the gap between business and IT.

The other difference is: –

Data Scientists not only understand the problem but also build a tool to solve it.

Whereas, Business Analysts take the output from Data Scientists and use it to tell a story.

  1. What is the difference between data science and statistics? 

Statistics is a mathematics-based procedure. This helps to find out and collect quantitative data. Data Science uses various scientific methods statistics is one of them. Yet, the fields differ in their processes and the problems they study.

  1. What is the difference between data science and machine learning?

Machine learning is the science of training machines. This help to analyze and learn from data the way humans do. This method assists data science projects to gain automated insights from data.

Whereas Data scientists might use machine learning methods as a tool. This also works closely with other machine learning to process the data as well.

  1. What is the difference between data science and data engineering?

Data Engineers build and maintain the structures that store, extract and organize data. Whereas Data Scientists analyze those data and predict trends and business insights.
