Pairs of distributions obtained under the same loading condition but for movements to different target sites (anterior versus posterior) could always be discriminated reliably from one another within the average number of observations per response (i.e. 42 video frames)
Overlap% indicates the percentage volume overlap of the two distributions
Probability is a measure of discriminability of the two distributions. It is the likelihood of predicting the wrong target condition from a single observation (one video frame)
No. required indicates the minimum number of observations needed to obtain a 95% chance of making a correct decision
