The Detailed Problem Analysis gives you detailed statistics and graphs of student performance on option response problems. For example, you can learn that many of your students set a particular foil to true when it is really false. With this information you can give your students feedback in order to help them better learn the concept the problem assesses. You have the option to choose to analyze your data over tries or time, analyze your data as concepts or foils, and select how many plots of the data you wish to view. Help links are provided on the the Detailed Problem Analysis screen which explain these options, in summary:

  1. Analysis over Tries results in each plot showing the results of a specific attempt by all students, meaning the first plot will show the results of the first attempt by all students, the second will show the results of the second attempt, and so on. Those students who get the problem right on the first attempt won't have a second attempt so the amount of data for each plot will decrease.

  2. Analysis over Time results in each plot showing the results of all attempts made during specified intervals.
