Mice Coursework
Introduction
In this coursework I am going to compare two sets of data about the weight of male and female mice. I am then going to make a hypothesis about the weights of these mice and then find out whether or not I am correct.
Hypothesis
My hypothesis is that male mice will be heavier than the female mice. I think this because usually males need to eat more and tend to be bigger.
Grouping the Mice.
In this coursework I will also have quite a few graphs.

So the mean average of male mice is 1710÷94= 18.20 (2 d.p. places)
From this we can already see that on average male mice are bigger in weight.
The next step that I will take is to draw the cumulative frequency graphs. I am drawing the cumulative frequency graph so that I can calculate the median value. The reason for this is because it

Mean Values
Female: 18.5G
Male: 18G
According to these mean values Female mice are heavier than Male mice.
