Biology Paper 5 help
« on: May 08, 2010, 10:19:05 am »
Hey guys, I was hoping if any of you could help me with this question from 07 for bio paper 5. It's just the first question and how to draw the histogram. I'm stumped on it. Though I do know how to draw a histogram I somehow can't get myself around this one. Help please! Thanks!

I just did that past paper a few hours ago at school (May/June 2007, right?), and I was also stumped!
I think I have to review my statistics, I've forgotten most of it (that and the fact that I got an E for Maths paper 6, Statistics1).

SOMEONE please HELP!! ???

The mark scheme only says "axes correctly orientated, suitable scale, labels; all plots correct; histogram drawn/plots adjoining;"
Like I understand that!

there are two samples. Both have 20 amount.
So degrees of freedom = 20-1 = 19 x 2 = 38
