Question

The numbers of bags of crisps sold per day in a general shop was recorded over 13 days.

The results are shown below.
32 45 36 56 45 68 29 48 21 45 32 47 59

In order from smallest to biggest, the results are:
21 39 32 32 36 45 45 45 47 48 56 59 68

The formula for finding out the quartiles didn’t work when I tried it.

Answer 1

I just figured it out so I’ll answer it on this account lol.

Q1 = 32, Q2 = 45, Q3 = 52

Interquartile range = 52 - 32 = 20

Range = 68 - 21 = 47
