Note: Tukey’s HSD test is conservative and increases the critical value to control the experimentwise type I error rate (or FWER). If you have a large number of comparisons (say > 10 or 20) to make using Tukey’s test, there may be chances that you may not get significant results f...
Visually, we can already see a clear improvement of the test scores over time in the meditators group. Let's look at the mean and standard deviations of the data:df.groupby(['Time', 'Group'])['Scores'].agg(['mean', 'std']).round(2)MEAN AND STD TimeGroupMeanSTD August Control ...
