WebJun 16, 2016 · If 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. The p value, or probability value, tells you how likely it is that your data could have occurred under the null hypothesis. It does this by calculating the likelihood of your test statistic, which is the number calculated by a statistical testusing your data.
