How Can Hot Water Freeze Faster Than Cold Water?
At first, it sounds crazy -- wouldn't hot water take longer to freeze? Weirdly enough, the opposite is sometimes true. Join Lauren to learn more about a mystery that's puzzled humanity for centuries in this episode of BrainStuff. p.s. - If you wanna conduct this experiment yourself, you h

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 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
