\label{Analysis_Analyze_Over}

Problem analysis has two ways of analyzing and displaying student submission 
data.
The data can be analyzed over \textbf{Tries} or \textbf{Time}.

Analysis over \textbf{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 \textbf{Time} results in each plot showing the results of all 
attempts made during specified intervals.
