meanA - meanB = 0.01
Repeat Permutations Of Samples
250 resampled differences shown
Each permutation resampling is done by:|
- randomly shuffling the combined set of 40 items contained in A and B,
- dividing that randomized set into two groups the size of the A and B samples,
- computing the mean value (i.e., the average) for each group,
- subtracting one mean value from the other, and
- using that difference-of-means value to increment the histogram.
The graph is split into two regions based on the original difference in the means of the A and B samples.
Each region is labeled with the percentage of the resamples for which the difference in the resampled means is on that side of the original difference.
