You can estimate the time needed to complete a study by using the following equation: Average (mean) completion time in minutes = .34 (number of items) + 4 For example if you have 50 items in your study then the average completion time = .34(50) + 4 = 21 minutes. Please keep in mind that is an estimated average, but one that is based on actual data. This equation was derived from a sample of 25 WebSort projects with the number of items ranging from 22 to 108. None of the studies used images as a study item.
