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

0.24 is the median.
The interquartile range is between the 1st and 3rd quartiles.
Check this site for figuring the IQR.
http://wiki.answers.com/Q/What_is_the_interquartile_range 
9 terms, so median is 24
first quartile .19
third quartile .255
IQR= .255.19=.065 or .07 
thank you both Ms. Sue for the site and bobpursley for assisting me in this problem.

You're welcome.
