If you already have advanced experience in Python, you’ll still need to familiarize yourself with the relevant math and statistics. Specifically, these areas:

  • Basic calculus principles
  • Linear algebra for performing functions
  • Probability and statistics
  • Discrete math for finite positions
  • Graph theory for solving certain problems

Your data science career path will typically only require general principles of calculus. However, probability, statistics, and linear algebra will come up daily for most data scientists.

  1. Data Analysis and Visualization Experience

Do you have experience as a data analyst working with visualizations? You’re in a great position to blend in some programming and become a data scientist.

Data scientists need to manage and manipulate data into useful insights. To do that, you’ll have to present reports, visualizations, and explanations to other people at a company who aren’t data scientists.

Anyone with SQL experience in business operations applications could also move swiftly through data science bootcamp if they have the other skills covered.

  1. Professional Background

Your current career might provide some leverage for breaking into data science if it matches the field’s often required skills. Software engineers with bachelor’s degrees or master’s degrees could make the most seamless transition to data science if they have a strong background in Python.

Software programmers, data analysts, and data engineers can also become data scientists in less time than those entering the field from other industries.

  1. Familiarity with Data Science Tools

Beyond programming and data analysis, you’ll need to apply these skills within the appropriate data science tools. You’ll need to learn the commonly used data science tools in business environments.

These tools typically fall into four main categories:

  • Data grabbing, storage, and cleaning
  • Data manipulation and transformation
  • Data modeling
  • Data visualizations and presentations
