Question

A student wants to report on the number of meals his friends buy each week. The collected data are below:

4 | 19 | 3 | 3 | 2 | 3 | 2 | 4

Which measure of center is most appropriate for this situation and what is its value?

a. Mean; 3
b. Mean; 5
c. Median; 3 <-- I think it's C? But I'm not sure.
d. Median; 5

Answer 1

C

Answer 2

I don't think it'd be A or B because 19 is an outlier. So that makes the distribution of data asymmetrical, which makes median the best measure of center.

Answer 3

Are you sure?

Answer 4

yup

Answer 5

Thanks!
