Thread: Chebyshev's inequality question

If 55% of data is 1.5s within the mean, does that mean I add and subtract .75s from the mean, or add and subtract 1.5s from them mean?

55% of data within 1.5 s of the mean means that 55% is in mean+/-1.5s.

But that is not the percentage/multiple that Chebyshev gives, a multipler of 1.5 corresponds to 44%.
