How to Become a Data Scientist?
Have you ever thought of a mathematician or statistician sitting in an IT company, doing software work, or vice versa? Well, the Data scientist’s job asks for it. It needs people to know math, statistics, domain expertise, and programming knowledge. One who is very interested in chunks of data and what they will do in this world can also be surprised by data science. Anyone with a basic undergraduate degree can become a data scientist. Many people are on the lookout for how to become a data scientist. I think that it’s the most searched topic on the internet.
What is Data Scientist?
Let us look into the details of a data scientist’s domain expertise, programming background, or mathematics.
1. Basic Mathematics
Many of us might have hated math in our childhood days, and we didn’t even like the tutor who taught math. I am here to reveal a well-known secret. Math, including algebra, matrices, and some calculus, is very much needed in data science. While exploring huge data, we will be in awe of how these ‘good for nothing’ matrices or calculus could do it. Math in itself is fascinating if one takes an interest in the subject. Develop a genuine interest in math, and you will do it right. Now folks, who love math like me, give the nod to you and go ahead.
2. Statistics
While learning probability and statistics during my childhood, I never thought that probability would follow me lifelong. However, the importance of statistics in data science is inevitable. We use many theorems and formulae of statistics to understand the data and predict the data’s future. Even if you get lost in the vast data, statistics can help you take the right path. Theories and formulae proven by great scientists will not fail, will they? Distribution and exploration of data can be done easily with the help of statistics.
3. Programming Skills
After getting an idea of data with the help of mathematics, it is nice to visualize it. What if some coding helps us to do this easily? Python and R are well-known programming languages that help data scientists do their work easily. Statistics easily works with both languages. The distribution and exploration of huge data can be seen easily with two or three coding steps.
It’s not necessary to know both the hand of the language in hand. However, expertise in one language helps you reach great heights in your data science career. If you are new to Python or R, take a deep breath and pull yourself up. Both languages are easy to learn and understand. Nothing can stop you from becoming a data scientist.
4. Data Visualization
Data visualization is very important in data science, as you should know how your data behaves after your analysis. If you can foresee it well, you are halfway done at the beginning of data exploration. While analyzing data, visualize where it can take you if you take it correctly. Or what happens if you take the opposite side of the road? People may laugh at me if I say creativity is an important part of data visualization. But this is true. Graphs and plots can help you do the work without doing all the calculations and coding parts. Some data visualization tools include Excel, Tableau, Google Charts, and so on.
5. Machine Learning
Data science is about analyzing the data; machine learning is building a model out of the data. Machine learning helps you understand labeled and unlabeled data, gives you a clear picture of various types of regression, and predicts how future data can be. With the advent of new technologies and various ways a new pile of data is being created, it is important to keep the data in our hands to be well-known and helps us predict our future. Machine learning helps in doing this. Traditional machine learning approaches can be dethroned by deep learning. Neural networks think like human brains, and bit AI will make our life easy with data. Basic knowledge of deep learning is important to be an efficient data scientist.
6. Data Knowledge
This should be the first topic on this page. Knowing your data is very important. The domain to which the data belong, whether any relevant columns are missing, the shape and size of data, and data behavior are necessary to derive proper conclusions. Missing data should be replaced or removed based on the relevance of the column. One should give proper care to finding out labeled and unlabeled data.
After properly studying the data, one must consider the regression method.
7. Communication Skills
Once data cleaning, exploration, and analysis are over, it is crucial to inform the team members and management of the developments. Communication skills come in handy over here. It is important to showcase your work with utmost patience in layman’s terms so that whoever is in the presentation should get a gist of the message you are trying to convey. Speak with the genuinely interested people in your work, get information from people who have been working for long years, and make everyone understand the importance of data analysis. Good communication helps in methodically doing all these things.
Conclusion
You should update yourself about the market and develop your data analysis accordingly. Work hard for your data and do a perfect analysis, as a small mistake means screwing up your organization. No one wants to do that. Data scientists can specialize through the best Data Science courses or in any field because huge amounts of data are present in every field of science worldwide. Knowledge of all the above topics cannot make you a skilled data scientist. You should be hardworking and open to new ideas always. As the world changes, so do the field of data.
