Cohen’s d Effect Size for t Tests (10-7)
An effect size is “a standardized measure of the size of an effect”. Unlike p values, effect sizes can be objectively compared to determine whether a treatment had any practical usefulness. Cohen’s d is the most commonly used measure of effect size for t tests. This video makes three point

Independent-samples T-tests 2: Effect Size
In this video, I demonstrate how to calculate the effect size for independent-samples t-tests and interpret the results. Three effect sizes are discussed: 1. Cohen's d: two groups have similar SDs and the same size. 2. Glass's delta: if each group has a different SD. 3. Hedges' g: differ

p-hacking and power calculations
P-values can be tricky things, and if we're not careful, we can report false positives much more frequently than 5% of the time. Here, I show how that can happen, and then I show to avoid it by doing power calculations - with an emphasis on the concepts behind the equations. For a complet

Why Should we REPORT Effect Size for Hypothesis Tests (16-10)
Significance tells us that the effect was likely not due to chance. Effect size is a standardized measure of how large the effect was. Cohen’s d is the most commonly used measure of effect size for t tests. There are three statistical reasons to report an effect size: if generalization is

Cohen’s d is the most widely reported measure of effect size for t tests. Although SPSS does not calculate Cohen’s d directly, there are two ways to get it. First, you can enter your SPSS output into a downloadable calculator that will give you the effect size. Second, (at 8:30) you can us
