9 Must have skills to become a Data Scientist.
Data science is tough to break in. This multi-disciplinary field is mostly based on maths, stats, and programming. To be a successful data scientist you must have these 10 skills which will take you to the next level as data scientist.
Okay, ready to start? Here we go.
“Statistics is the grammar of data science.”
When you start writing a sentence you must be clear about the grammar concepts to build your sentences in a similar way statistics is an essential concept for you to understand to build your high-quality models. The main advantage of statistics is that the information is presented in an organized way which will help us a lot.
Here are some basic concepts in statistics for becoming a Data Scientist!
- Types of Analytics
- Probability distribution
- Regression Modeling
Most machine learning models are built with several unknown variables. Knowledge of Calculus is significant for building a machine learning model.
Here are some basic concepts in calculus for becoming a Data Scientist!
- Gradient Descent
- Multi-Variate calculus
3. Linear Algebra
It is necessary to understand Linear Algebra to step up into machine learning. With Linear Algebra, you can develop a better intuition for machine learning algorithms. Learning Linear Algebra would help you to choose the necessary parameters and develop a better model.
Here are some basic concepts in Linear Algebra for becoming a Data Scientist!
- Matrices and Vectors
- Matrix Operations
- Matrix Inverse
- Orthogonal Matrix
- Applications of Linear Algebra within Data Science (SVD and PCA)
Programming gives us a way to communicate with our machines. So, you would have a question for yourself. Do you need to become the best in programming? The answer is
Firstly you should choose a programming language. or are the popular programming languages learned by data scientists, each language has its own set of pros and cons. is a general-purpose programming language, and having multiple libraries with rapid prototyping makes it useful for data scientists. is a statistical analysis and visualization language.
Usually, everyone starts with Python as their primary language, because Python is found to be a more accessible language to perform machine learning tasks.
5. Data Manipulation and Analysis
Data Manipulation which is also known as Data Wrangling is the skill where you clean your data and transform it into a format that can be useful for analyzing it. Data Manipulation takes a lot of time but it will help you in taking better data-driven decisions. Data manipulation is done in areas such as missing data, outlier treatments, correcting data types, scaling, and transformation.
Data Analysis is the step where you understand a lot about your data. Data Analysis can be done by using the library in Python.
6. Data Visualization
Data Visualization is considered the fun part of machine learning. To start with data visualization one must be familiar with histograms, bar plots, and pie charts and move to advanced plots like waterfalls charts, etc. These plots will be very useful during exploratory data analysis.
Data visualization is where you can relate your bi-variate and multi-variate variables with colors. Data Visualization can be done in Tableau, Matplotlib, etc.
7. Machine Learning
For every data scientist, Machine Learning is the core skill to have. For example, if you want to predict the number of customers you will have in the next month by looking at the past month’s data, you will need to use machine learning algorithms.
You can start learning Machine Learning with simple algorithms like linear and logistic regressions and climb up to other models like Random forests, Gradient boosting, etc. It is really easy to remember the line of code for your machine learning algorithm which hardly takes only 3–4 lines of code but the most important thing is to know how they work.
8. Communication Skills
“Good communication is just as stimulating as black coffee, and just as hard to sleep after.” — Anne Morrow Lindbergh
Communication Skill is a soft skill. Communication Skill here refers to the skill with which you communicate with your fellow mates with data. Effective communication is necessary for quite a few reasons.
You can improve your communication skills by
- Concentrating only on the sum and substance of thoughts.
- Focusing on Outcomes and Values
- Use empathy
- Speak the language of the Business
9. Story-Telling Skills
“Story telling is the far most underrated skill in business.
The art of Story Telling is a very critical skill for every data scientist. Stories are truer than the truth. Every data scientist should also be a storyteller because it brings in simplicity. Storytelling makes our data interesting also stories provoke thought and bring out some useful insights into our data. This also helps in understanding the logic behind every data and analysis.
With time data analytics are growing bigger and better. It is expanding the number of people generating insights, increasing the need for more data storytellers in the future. Therefore, data scientists should not only stick to numbers and their analytical skills rather they should train themselves to become good storytellers with the use of their data.
