Introduction to Statistics for Psychological Research

This course will begin by introducing the basic concepts of how to describe and visualize data, the fundamentals of using statistics to make inferences, and the logic of null hypothesis testing. Various types of hypothesis tests will be introduced, along with criteria for selecting which is appropriate for different study conditions. As an extension of null hypothesis significance tests, you will learn about how to interpret effect sizes and confidence intervals, along with statistical power, before being introduced to alternatives to null hypothesis significance testing.

Data Analysis Basics

Null Hypothesis Significance Testing

In this module, we move on from descriptive statistics like the mean and standard deviation into inferential statistics, which help us use sample data to draw inferences about the populations the samples represent.

Beyond Null Hypothesis Significance Testing

In this section of the course, we consider the role of null hypothesis significance testing in psychological research, some objections that have been raised to that approach, and some alternative approaches that have been proposed.
