Thank you! I've been looking for this!

[@NAJJEMBARUTH]

why subtract 0.5 from the lower limit of 50?

PLS THE 75TH POSITION IS IT CONSTANT?

[@JEROMEMACAYAN]

why you use 100? since it is not percentiles?

[@KcseMathsTutorials]

Total frequency is 100

[@dkinobe]

Thanks comrade, others indicate quartile deviation as Q3-Q2 divided by 2, while here you are using Q1, why?

[@basibasimaria]

Wrong. It should be 65 not 70, so it will stop from 95. And the total of N=95, it shoud be the same.

[@carolynemwende272]

its 3.5 not 2.5
