Hi
I have not checked you answers yet, but in the mean time I hope this may help you.
I haven't made one in a long time and just want to make sure it's correct. The .pdf is the actual graph I made. It's not to scale or anything. I'm more interested in whether the numbers are correct. The .pdf file is the data set and how I calculated the numbers. If someone knows a way of creating a box and whisker plot using Excel, I'd love to learn how. I've tried looking online in the past but haven't really found anything.
I didn't label it but there are fifty values in the data set.
Sorry that it's taken me so long to respond. I should have posted the manner in which I got all of my numbers. Anyway, here goes:
13th value in the ordered data set=7
value in the ordered data set=10
38th value in the ordered data set=16[/tex] (I messed up on this one)
Now, for the upper and lower whiskers, I was taught to take the interquartile range (IQR) , multiply it by 1.5 and then add the product to the to find the upper whisker and subtract the product from [tex]Q_{1} to find the lower whisker. So that would be:
But since the lowest value in the data set is 3, 3 becomes our lower whisker. I screwed up on that too.
Upper whisker is 29.5. There is one value (32) higher than the upper whisker. That value is an outlier.
