... Ahelp: goodness − CIAO 3.4 Note that the accuracy of Q is dependent upon whether the selected statistic is actually sampled from the chi−square distribution! This may not be the case if the number of counts in any bin is too small (< 5−10). The information output by GOODNESS may be retrieved using ...

Mitosis Data Analysis: Testing Statistical Hypotheses
... Remember that we have defined our significance level (a) as 0.05. This implies that a correct null hypothesis will be rejected only 5% of the time, but correctly identified as false 95% of the time. A critical value of a statistic (e.g., your Mann-Whitney U statistic) is that value associated with a ...
