P-value

The p-value is a statistical measure indicating the probability of observing test results at least as extreme as those observed, assuming the null hypothesis is true.

Consecutive Weeks

A series of weeks that follow one after another without interruption, often used in the context of scheduling or data collection.

Sign Test

A non-parametric test used to determine if two related paired samples come from the same distribution, without assuming a parametric form for that distribution.
