The document discusses histograms created from data collected on students in Mrs. Lay's 6th grade class. It analyzes histograms of students' scores on hand slap, stopwatch, and ghost blaster activities to determine characteristics of the typical 6th grader. The histograms show that on average, students scored 19.44 on ghost blasters, 29.704 seconds on the stopwatch, and 3.19 hand slaps. This indicates that the typical 6th grader is average at these activities, better at some than others, but not extremely fast or slow. The document also analyzes whether boys or girls were faster, concluding girls had the best scores on average.

7. The reason I chose histograms One 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.

8. HAND SLAPS Hand slap histogram AMOUNT OF SLAPS F R E Q U E N C Y AMOUNT OF SLAPS

9. Stop watch histogram STOPWATCH TIMES 24-25 26-27 28-29 29-30 31-32 TIMES

10. Ghost blaster histogram GHOSTBLASTER SCORES 12 11 10 9 8 7 6 5 4 3 2 1 0 -30—20 -21—10 -9-0 1-10 11-20 21-30 31-40 41-50 51-60

11. 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.

12. The typical 6 th grader The typical 6 th 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.

13. 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.
