A video tutorial on how to calculate the quartile deviation of a grouped data

[@theodoresweger4948]

I loved the way you explained this. what is weird to me is nothing to do with your explanation which was excellent, but my HP prime program has an error and comes up with near solutions which are wrong, but you are correct

[@KcseMathsTutorials]

Thanks..which is that HP program?

[@kofitik3se39]

Perfect tutorials

[@NAJJEMBARUTH]

why subtract 0.5 from the lower limit of 50?

[@soulpaulx5947]

class boundary

[@KcseMathsTutorials]

Many confuse boundary and limit

[@MaryAoko-q5q]

Thank you so much sir for that explanation

[@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.

its 3.5 not 2.5

[@dkinobe]

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