The reason I chose histogramsOne reason I chose histograms is because it
helps show gaps if there is no bar on top of the intervals.
Another reason I used histograms is because it helps show outliers if there is a small number on a interval that is far away from the clusters.

Graph variability
The stop watch graph has 2 gaps which are 26-27 and 28-29 but the ghost blasters graph and hand slap graph only has 1 each.
-35, -9, and 24.31 are the only outliers in the graphs
All the histograms cluster in a general area at 18-8. But the hand slap graph also clusters around 7-5.
The typical 6th grader
The typical 6th grader ranges around 19.44 in ghost blasters 29.704 in stop watch and 3.19 in hand slap they are not extremely fast but not very slow. They are not as good as they are at certain activity's as the are with others like stop watch and hand slaps.
I know this because 19.44, 29.704, 3.19 are the mean and the mean is the best way to show the average. I know they are better at certain activity's because 29.704 is one of the best scores and 3.19 is not so good.
Who's faster Boys or Girls?I think that the girls are faster the reason I think this is because the best scores are by the girls
To support my answer I showed the mean because all the averages were made by mostly
girls or were closer to the girls scores.
