I'm being told to "Use more than one measure of location in the comparisons. There is no need to use measures of dispersion."
So I think that means I need to find the Mean Median and Mode for each set. Which I can do except for the Mode because there are no repeated numbers in each set. I believe I need to make some kind of frequency distribution graph, but I don't see how I can do that, there are no frequencies.
This question is worth 8 marks so I'm sure they want more from me than just the Mean and Median and a sentence saying "a is greater than b, b and c are very similar". What am I missing?
Any help is very greatly appreciated, thanks.
That sounds very complicated...
That sounds good, and thanks very much for the answer. But it looks complicated, and perhaps too far. I looked ahead to next weeks lecture notes and they mention box plots, which I had forgotten about, and to make one for each data set seams like a good way to do it, it allows me to compare them easily. Does that sound like a good idea?
I'm not sure what level it is, its a maths module in a sociology course, it feels like AS level.
