Our class went to measure 1st graders and to compare it to 4th grade heights, here is what my partner and I found out.The median for 1st grade is 48″ (middle). The median for 4th grade is 56″.It shows that 1st graders are shorter than 4th graders.
The mode(most people) for 1st grade is 49″. The mode is 54″ and 56″.This shows that a ton of kids in 1st and 4th grader’s heights are this height.
The range for 1st grade is 18″. The range for 4th grade is 10″.This shows that the 4th graders are more spread out than 1st graders are.
The outlier for 4th grade is 61″. There is no outlier for 1st grade. This shows that the tallest person is far away from everyone.
The clump for 1st grade is 45-49.The clump for 4th grade is 54-56.This shows that more people in 4th grade are between 54 and 56 and for 1st grade is between 45-49.This is what we found out!
I don't really have any theories
You compared the data in a very interesting way here, although I think that the range is not correct for the fourth grade. I think that your comparison of the ranges is fascinating. Why do you think that the first graders were more spread out in height? Any theories?
