Then you need to collect some data.
Get 30 students who are constantly late and 30 who are always on time.
Record their grades. We can then do some stats to see if there is
a correlation. The more the merrier but you need at least 30 for
the stats to hold any credibility.
Get the same 30 students who are late all the time and the 30 students
who are always on time. Note how many from each group graduate.
Same deal.
