sir why do we use 1.5 to multiply the IQR at 2:17, like why specifically 1.5

[maximusekon]

Regarding that stuff about outliers are you basically trying to say that if I am given the raw data then I CANNOT take the lowest value on boxplot as my boundary and instead i have to work it out manually

Hello sir, i am quite confused as to when i should add one and when i should just divide by 2 to get the median position. my text book seems to just add one so that it gets a whole number but that doesnt seem very statistical lol
Thanks for the help

Why is it LQ-1.5xIQR specifically? Why 1.5?
