WebIt's a t test to see if we have evidence that would suggest our alternative hypothesis. And so what we do is we assume the null hypothesis. From that you're able to calculate a t-statistic, and then from that t-statistic and the degrees of freedom, you are able to calculate a p-value. And if that p-value is below your significance level, then ... WebStep 2: Determine whether the difference is statistically significant. To determine whether the difference between the medians is statistically significant, compare the p-value to the significance level.
