Guesstimate
Introduction
All pupils in Yr7 and Yr10 were asked to guess the length of a line and the size of an angle. I will be looking and investigating the results between the in yr 7 and the results from yr 10.
Hypothesis
* Age ~ The group of Yr10's may measure the line and angle more accurately because they have been in education for longer and have more practice.
* Gender ~ The girls may measure the line more accurately because its proven that girls try harder in schools than boys.
Plan
The raw data for this experiment has been collected for me, this is called secondary data. If I was to collect the data myself this would be known as primary data.
From my raw set of data I will be selecting what results I am going to use by the method of Random sampling. I will be doing this by giving the set of results a number and then from that I will press the 'random' button on the calculator. This will then determine what results to use from the table. I chose this method because I thought it was the fairest, other methods of sampling include:
* Systematic sampling - Samples taken in a periodic and regular fashion. The periodicity may be distances in 1, 2, and 3 directions, in regular angular increments, or in any other periodic fashion.
