How to learn Data Science efficiently?

Data Science requires knowledge of various fields such Statistics, Calculus, programming languages, database languages, and many more. But for acquiring multiple skills there should be a systematic approach that you should keep in mind. In this section, we will discuss about few of the approaches where you will understand how can you effectively learn Data Science and they are:

1. Learn to choose appropriate data

As we already know Data Science is nothing without data. Thus, it becomes necessary to extract appropriate data for solving a particular problem. If the data is inappropriate, you will find it difficult to implement Data Science techniques in it and end up messing all the things. Therefore, to get the most out of the Data Science field you must learn to choose data properly. For this, you should start with common datasets such as weather prediction, insurance cost prediction, product recommendation, fraud detection, and customer churn. Understand these basic datasets and try to draw meaningful conclusions from them.

2. Learn by implementing

This is the best answer for the question how to learn Data Science. The best way of learning Data Science is by implementing all the techniques in a project. There are multiple techniques such as data extraction, manipulation, visualization, and building models using ML algorithms. Pick up any interesting project of your choice and start working on it. This will help you to strengthen your implementation skills. Start with data cleaning and visualization of data. Then, build predictive models using various Machine Learning algorithms. Also, working on projects will help build a decent portfolio as a Data Scientist.

 3. Constantly increase the degree of difficulty

Working on simple datasets will not make you an expert in Data Science. You need to increase the level of difficulty. There are multiple datasets available that require strong implementation skills and an in-depth understanding of multiple fields. Therefore, working on varieties of complex data will help explore the field of Data Science.

 4. Learn from the Data Science community

You can find a large community for Data Science as it is one of the most popular technologies in the world. There are Data Scientists who shares their knowledge and experience of working in Data Science projects. Also, the aspiring Data Scientist posts wonderful ideas and solutions for Data Science competitions. It will help gain more knowledge of various approaches to get the best solution and find the mistakes that you are doing.

Till now, you must have got a clear idea about how to get started with Data Science. Further, let us have a quick glance at top 10 skills for Data Science aspirants.
