Question

Please help anyone if you can This one is really confusing me I need the IQR for these set of numbers
0.10,0.18,0.20,0.21,0.24,0.24,0.25,0.26,0.28
What I did was place them in order and worked my way from both end until I got in the middle I came up with 0.24 but not sure if it's right

Answer 1

0.24 is the median.

The interquartile range is between the 1st and 3rd quartiles.

Check this site for figuring the IQR.

Answer 2

9 terms, so median is 24
first quartile .19
third quartile .255

IQR= .255-.19=.065 or .07
