DATA VARIABILITY

About 2/3 of the students have the ghost blaster scores between 16 and 35 points.

The outliers are -35, -9, and 51.

In the histogram there were a major gap between the number -24 and -15.

A lot of the data clustered between 29 and 41 points

“TYPICAL” SCORES OF GHOST BLASTERS IS…

I think the “typical” scores of the students who play ghost blaster in Mrs. Lay’s 2nd

Period Class is about 20 points. I think that because the mean and the median are very close to 20 points if not exactly 20 points. Also the clusters in the line plot are around

the 20 mark. The mode is 17/28 which, considering all numbers the mode is really

close to the 20 mark too.

“WHO’S FASTER, GIRLS OR BOYS?!?!?!”

In the end the gender that I believe that came out on top was the boys. I believe this because if you look at the line plot you can easily see that even though the

girls have a big gap of 51 points they still have a huge gap of -35 and -9 point and the boys have their data clustered very close together and the girls have their data very far apart. If you can, you can also see that the boy’s mean and median are both bigger than the girl’s mean and median, which is why I think the guys

are more constantly with their data then the girls.
