What a p-Value Tells You about Statistical Data - dummies

WebIf you plot x vs y, and all your data lie on a straight line, your p-value is < 0.05 and your R2=1.0. On the other hand, if your data look like a cloud, your R2 drops to 0.0 and your p-value rises. WebBecause with a big enough sample size, any difference in means, no matter how small, can be statistically significant. P-values are designed to tell you if your result is a fluke, not if it’s big. Truly the simplest and most straightforward effect size measure is the difference between two means.
