WebJul 16, 2024 · The p value gets smaller as the test statistic calculated from your data gets further away from the range of test statistics predicted by the null hypothesis. The p value is a proportion: if your p value is 0.05, that means that 5% of the time you would see a test statistic at least as extreme as the one you found if the null hypothesis was true. WebMay 1, 2024 · Definition: simple linear regression. A simple linear regression model is a mathematical equation that allows us to predict a response for a given predictor value.
