The … WebMar 10, 2024 · P-value is a measurement that assumes the null hypothesis is correct, meaning that if the value is small, then you can reject the null hypothesis in favor of the alternative hypothesis. A large p-value typically means that the data point or set you measured aligns with the null hypothesis, making it the more likely outcome.

Hence, there is a significant relationship between the variables lstat and mdev in the linear regression model. WebWe use p p -values to make conclusions in significance testing. More specifically, we compare the p p -value to a significance level \alpha α to make conclusions about our hypotheses. If the p p -value is lower than the significance level we chose, then we reject the null hypothesis H_0 H 0 in favor of the alternative hypothesis H_\text {a} H a.
