I sometimes find QAPonline posts very large SD from the group mean. Sometimes the size is silly and not possible. What could cause this? This essentially indicates that the summary files that record your performance need to be updated. Each time you complete an exercise, QAPonline records in these summary files your performance as SD from the current mean. However as more replies are submitted, the mean and SD will change gradually approaching the long term values. If QAPonline has not updated these files, you should look for the menu option REFRESH and this should reset the values in the files with the most recent estimate of your performance. |
