WebAboutTranscript. We compare a P-value to a significance level to make a conclusion in a significance test. Given the null hypothesis is true, a p-value is the probability of getting a result as or more extreme than the sample result by random chance alone. If a p-value is lower than our significance level, we reject the null hypothesis. WebWhat is the T Statistic used for? When you run a hypothesis test, you use the T statistic with a p value. The p-value tells you what the odds are that your results could have happened by chance. Let’s say you and a group of friends score an average of 205 on a bowling game.

Then we look at the two-tailed row at the top to find the corresponding p values for the two t-values. In this case, our t-value of 2.289 produces a p value between 0.02 and 0.05 for a two-tailed test. eagleson training
