Answer to Question #328411 in Statistics and Probability for Lisa

Question

Given the mean monthly expenditure of students is RM200 with RM1O standard

deviation and the mean weight of the student body is 50 kg with a standard deviation

of 8kg. Compare the two sets of data and determine which are more scattered.

Answer 1

$CV_1=\frac{10}{200}=0.05.$

$CV_2=\frac{8}{50}=0.16.$

Since the coefficient of variation for the set 2 is higher, this set is more scattered.
