I'm doing coursework (nearly finished) for Monday, but might have come upon a HUGE mistake i've made.
What i'm doing is this hypothesis:
"The advertising in a national newspaper is a greater amount than a regional newspaper"
So, I counted all of the adverts on every page and put them onto a tally with
page | number of adverts
1 > > > > 1
2 > > > > 3
and so on...
So, I was told to find the cumulative frequency (add up the adverts on the way down (1+3 for above)). Then to put them on a cumulative frequency diagram.
So, after doing that, I found the median, which was page 17 or something, then, the lower quartile, which was a decimal number (like 5.8 or something)
Until I finished, I thought it was fine, then realised that that would only work if it was cm or minutes which was the bottom of my diagram, because, there is no page 5.8.
Does it still work?
Am I panicking over nothing?
