[@dicksoneyenegho]

why are you multiplying by 1.5? It was not explained. Somebody please help me too?

[@breeharden9346]

I would like to know as well. Did anyone clarify this?

[@breeharden9346]

after taking the 1.5 into more consideration, the bell-shape distribution usually has an outliner of 0.15%. To include this in the IQR, it looks like the 0.15% was converted to a whole number by moving the decimal over one spot. Thats my "educated guess"..lol

I was looking for How to calculate IQR online today, after watched several videos and reading solutions, I think the method you used here maybe easy to understand, but the result may also be wrong. When calculate Q1 and Q3 by , by using formula (n+1)/4 and (n+3)/4, you get 5.25 and 15.75, therefore Q1= 9x0.75+ 10x0.25= 9.25 Q3=21x0.25+23x0.75 =22.5 and the IQR=Q3-Q1=13.25

[@DavinderSingh-ik1jj]

Kpa 19.4 normal range

[@ABDULRAHMAN-yk9jv]

Q1 IS 9.25 NOT 9.5

[@anurajms]

how is q1 9.25?
