Inferential Statistics

Learn how statisticians use sample data to understand populations, estimate unknown values, measure uncertainty, and make evidence-based statistical decisions.

What You Will Learn

Inferential statistics is about going beyond the data you directly observe. Instead of only describing a sample, you learn how to use sample evidence to estimate population characteristics and evaluate statistical claims.

Throughout this course, you will work with concepts such as sampling, sampling distributions, the Central Limit Theorem, confidence intervals, hypothesis testing, p-values, t-tests, chi-square tests, and ANOVA.

Sampling

Learn how samples are selected and why sampling matters when studying large populations.

Estimation

Learn how sample statistics can estimate unknown population parameters.

Confidence Intervals

Understand how statistical intervals communicate uncertainty in estimates.

Hypothesis Testing

Learn how statistical evidence is used to evaluate hypotheses.

Statistical Tests

Work with t-tests, chi-square tests, and ANOVA.

Data Analytics

Apply statistical concepts to realistic data analytics problems.
