WebOct 15, 2024 · A small p-value might simply be a sign that data analysis rules were broken. There was a real but tiny relationship, so tiny that we shouldn’t really care about it. A large trial can detect a true effect that is too small to matter at all, but a p-value will still flag it as being surprising. There was a relationship that is worth more study. 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.

A test statistic enables us to determine a p-value, which is the probability (ranging from 0 to 1) of observing sample data as extreme (different) or more extreme if the null hypothesis were true. The smaller the p-value, the more incompatible the data are with the null hypothesis. A p-value ≤ 0.05 is an arbitrary but commonly used ...
