Instructions

Below are two dot plots created from the data we collected from Period 4 and 7 on the number of letter's we had in our full names. Answer the questions below using the dot plot and other given information.

Required

Question 1

What is the average (mean) number of letters in a student's name from Period 4? (Round to the nearest tenth)

Required

Question 2

What is the average (mean) number of letters in a student's name from Period 7? (Round to the nearest tenth)

Required

Question 3

Based on the two means, which class contains student's with longer names?

Period 7

Period 4

Both classes contain student's with name's of similar length

Required

Question 4

Find the Mean Absolute Deviation for Period 4. (Take the mean of Period 4's data and subtract it from each data point in the dot plot. Make sure to change any negative value to positive and then find the mean of those 19 results) Round to the nearest tenth as necessary

Required

Question 5

Considering the Mean Absolute Deviation for Period 4 and that Period 7 has a MAD of 3.4, what can you infer about the data?

The distribution of letters in one's full name for Period 4 is larger than that of Period 5

The distributions of letters in one's full name are nearly equal between the two classes

There is not enough information given

The distribution of letter's in one's full name for Period 4 is smaller than that of Period 5
