If you want to become a skilled data scientist, you should know how to understand and analyze data. And for this statistics is important.

However, learning statistics can feel difficult, especially if youâ€™re not from a math or computer science background. But don't worry. Weâ€™ve compiled a list of statistics coursesâ€”from introductory statistics to slightly more advanced conceptsâ€”which you can take for free.Â

You don't have to take all of these courses to become proficient in statistics for data science. So please feel free to check out the courses that you particularly find interesting. Letâ€™s get started!Â

Note: You can audit all of the following courses for free on Coursera.Â

# 1. Introduction to Statistics

The Introduction to Statistics course from Stanford is a good first course in statistics. This course aims at teaching all the statistical thinking concepts that are necessary to understand and analyze data.Â

Hereâ€™s an overview of the course contents:

• Introduction and descriptive statistics for exploring dataÂ
• Producing data and samplingÂ
• ProbabilityÂ
• Normal approximation and binomial distributionÂ
• Sampling distributions and the central limit theoremÂ
• RegressionÂ
• Confidence intervalsÂ
• Tests of significanceÂ
• ResamplingÂ
• Analysis of categorical dataÂ
• One-Way Analysis of Variance (ANOVA)
• Multiple comparisons

# 2. Basic Statistics

Basic Statistics from the University of Amsterdam is also another beginner-friendly statistics course. This course requires you to be familiar with R programming and covers the following topics:

• Exploring dataÂ
• Correlation and regressionÂ
• Probability and probability distributionÂ
• Sampling distributionsÂ
• confidence intervals and significance tests

# 3. Statistics for Data Science with Python

The Statistics for Data Science with Python is offered by IBM as part of the Data Science Fundamentals with Python and SQL specialization.Â

This course will teach you how to use Python to perform statistical tests and interpret the results of statistical analyses. The contents of this course are as follows:

• Basics of PythonÂ
• Introduction and descriptive statisticsÂ
• Data visualizationÂ
• Introduction to probability distributions
• Hypothesis testingÂ
• Regression analysis

# 4. The Power of Statistics

The Power of Statistics is offered by Google as part of their Google Advanced Data Analytics Professional Certificate.

From summarizing datasets to conducting hypothesis tests and modeling data using probability distributions, this course also focuses on statistical analysis with Python. This course covers the following topics:

• Introduction to statisticsÂ
• ProbabilityÂ
• SamplingÂ
• Confidence intervalsÂ
• Introduction to hypothesis testingÂ

# 5. Statistics with Python

The Statistics with Python Specialization offered by the University of Michigan teaches you how to use Python for data visualization, statistical inference, and modeling. It also emphasizes the importance of connecting the business questions you need to answer to the relevant data analysis methods.

This is a three-course specialization that covers the required theory as well as Python programming assignments to help you apply all that youâ€™ve learned. The courses in the specialization are as follows:

• Understanding and Visualizing Data with PythonÂ
• Inferential Statistical Analysis with PythonÂ
• Fitting Statistical Models to Data with Python

# Wrapping Up

And that's a wrap. We went over five courses that you can take for free to learn statistics and level up your data science skills.Â

Because most of these courses focus on programming and running statistical tests with Python as opposed to learning only theoretical concepts, Iâ€™m sure youâ€™ll find plenty of opportunities to apply what youâ€™ve learned. Happy learning, and keep coding!
