What is statistics?
Statistics is a branch of mathematics focused on the collection, analysis, and interpretation of data. Data sets can include full population data, surveys, smaller random samples, qualitative data, and much more. Statisticians can apply a number of data analysis techniques to better understand what the data means and how different data points or data sets relate to each other. For example, a pollster can conduct surveys on voter sentiment to determine which issues are likely driving voters to the polls. They can also use statistics to determine how closely their sample of voters reflects the larger population.
Where Can I Find Free Statistics Courses Online?
The following universities offer college-level statistics courses online. Although students cannot use their time online to earn college credit towards a degree or certificate program, much of the content of these courses is available to self-learners for free and without the need for registration or enrollment.
Online Statistics Courses for Credit
Massachusetts Institute of Technology
The Massachusetts Institute of Technology (MIT) first launched its OpenCourseWare site in 2000. Today, the school publishes almost its entire undergraduate and graduate course content online for free. Many undergraduate and graduate-level statistics courses are available through MIT’s mathematics OCW program, including:
- Introduction to Probability and Statistics goes over topics such as basic combinations, random variables, probability distributions, and more.
- Statistics for Applications looks at subjects like confidence intervals, hypothesis testing, chi-square tests, and related statistical uses.
- Statistical Learning Theory and Applications focuses on several core aspects of computational neuroscience while looking at concepts related to boosting and feature selection.
- Mathematical Statistics centers around decision theory and estimation while also examining topics like asymptotic efficiency of estimates.
The Open University, based in the United Kingdom, was founded with the mission of providing quality online learning. It has an open admissions policy, and enrolled students can earn a degree or certificate online. However, the school also offers many courses for free via an OpenLearn website, The Learning Space. Students can check out the following when searching for statistics courses:
- Finding Information in Mathematics and Statistics aims to help students identify and employ statistical information for a wide variety of purposes.
Carnegie Mellon University
Carnegie Mellon University (CMU) is a participant in the Open Learning Initiative, a sister project to OpenCourseWare.

- Empirical Research Methods looks at topics such as random variables, data samples, interpreting graphs, and more.
Johns Hopkins University
The Bloomberg School of Public Health at Johns Hopkins University (JHSPH) offers its most popular courses online via OpenCourseWare. The school’s mission is to provide equal and open access to information about public health challenges and their solutions. The courses are, therefore, all related in some fashion to issues in world health. Statistics-related OpenCourseWare courses at JHSPH include:
- Introduction to Biostatistics goes over several matters of data and data types while serving as an introduction to biostatistical concepts and reasoning.
- Biostatistics for Medical Product Regulation fleshes out topics like basic study design, target population, comparison groups, and endpoints.
- Methods in Biostatistics I and II introduces concepts of applied probability, exploratory data analysis, and statistical interference while expanding on topics of probability models, variance, central limit theorem, and more.
- Statistics for Laboratory Scientists I and II looks at the basic applications of statistics within experimental biological sciences while demonstrating methods of exploring, organizing, and presenting data.
- Statistics for Psychosocial Research: Structural Models centers on quantitative approaches to constructing theory based on response variables while exploring topics like the statistical basis for causal inference; principles of path analysis; linear structural equation analysis, and related concepts.
- Statistics in Psychosocial Research: Measurement offers quantitative methods of measurement in psychological fields of study while delving into the principles of psychometrics, the statistical basis for latent variable analysis, and more.
