WebSo we have a p-value of 0.029, which is less than our selected alpha value of 0.05. Therefore, we reject the null hypothesis that the means of Line A and Line B are equal. Note also that while the evidence indicates the means are different, that difference is estimated at 0.338 oz—a pretty small amount of cereal. So far, so good. WebThe p-value and effect size must both be taken into account when interpreting the outcomes of a significance test. A crucial indicator of statistical significance is the p-value. In the event that the null hypothesis is correct, it is described as the likelihood of having a result at least as extreme as the observed outcome. cheryl stewart oakley ksWebThe usual way of doing this is to test your results with a p-value. A p value is a number that you get by running a hypothesis test on your data. A P value of 0.05 (5%) or less is usually enough to claim that your results are repeatable.
