An investigation to compare the height and weight of the girls and boys at Mayfield School.

   For my investigation, I am going to compare the height and weight of a percentage of the girls and boys in year 10 at Mayfield School to see if there is a correlation between the two sets of results. I am then going to see if there is a correlation between my first set of results and the results of the girls and boys height and weight in year 11.

   I predict that the taller people in the year group will weigh more than the shorter people. I think this because people who are taller have a bigger mass and will therefore weigh more. For the second part of my investigation, I

   To represent the first group of data, I will draw a scatter graph and I will then put in a line of best fit and explain what correlation there is to see if there is a connection between the two groups of results. For the second part of my investigation, I will do another scatter graph to show how I have interpreted my results.

   Firstly I am going to remove any anomalous data so I know exactly how many students I have to take my sample from. After removing all of the anomalous data, I have established that there are 198 people in year 10. This means that I will be using a sample of 66 pupils. Next I have to find out which students I am going to use. To do this I will use the random control on the calculator. I have now got my sample.image00.png

Conclusion

   The two trend lines on the graphs are not as I thought they would be, the one for the year 11’s has a much steeper gradient than the one for the year 10’s which is far more level. Also in the year 10 graph the points are all in a cluster whereas in the year 11 one they start off in a cluster and then the points graduate up to higher up to the left of the trend line.  Although on both of the graphs, the main cluster of the points is in between 1.5m and 2m on the x-axis.

    You can see from above when I made the graphs that for males, females and all the students put together they had a positive gradient. The equation for the line of best fit clearly shows a positive gradient thus therefore there is a positive gradient.

    This was done at random by writing "year 7 girls", "year 7 boys" and so on, on a piece of paper and putting them in black bag. Without looking, I picked out one of the papers which read "year 11 girls".

    It also shows me that the most frequent height is 1.62 meters which is more than the average. Standard deviation is a formula that finds the average deviation from the average. The formula for it is V1/n?(x-mean)�. In this case the standard deviation is less than 10% of the mean
