Question

The data represent the number of cans collected by different classes for a service

project.

12 14 22 14 18 23 42 13
9 19 22 14

a. Find the mean.
b. Find the median.
c. Eliminate the greatest value, 42, from the data set. Explain how the measures of
center change.

Answer 1

mean is 18.5 (add all values ÷ total number of values)

median is 16( arrange scores in ascending order and start removing scores from both the sides, 2 scores and up in the middle which were 14,18 add them and divide by 2)

omission of 42 will make the median 14(I'm not sure about this answer)
