Question

The mean for the number of pages of a sample women's fitness magazine is 132, with a variance of 23, the mean for the number of advertisment of a sample of women's fitness magazine is 182. compare the variation

Answer 1

The coefficients of variation are:

$CVar(pages) = \sqrt23/132×100 = 3.6$%.

$CVar(ads) = \sqrt62/182×100 = 4.3$

%.

So, the number of advertisments is more variable than the number of pages.
