### LON-CAPA Help

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:

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