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

  • ALGEBRA -

    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

  • ALGEBRA -

    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.
