Hypothesis

  1. The average height and weight for boys is greater than for girls.  
  1. My other hypothesis is that there will be a positive correlation between height and weight e.g. the taller you are the more you weight.  

Number of pupils

There is an un-equal spread of boys and girls form year 7-11.  When I choose my sample I must take this into account.  I am going to choose 100 pupils out of the 1183 pupils attending Mayfield High school.  To do this I will have to multiply every total in table A by 100/1183 (=0.0845) and get the values in table B.

Conclusion

  1. As I predicted the average height and weight for males was greater than for females.  However, this turned out to be much lower than I expected.

                   F     M

Height   (1.58-1.62)

Weight  (47.25-47.51)

If you compare the results for year 7, 8, 9 and year 10, 11 we found that there was very little difference in year 7, 8, 9.  This is probably due to the fact that year 7 girls develop earlier than year 7 boys and then year 7 boys catch up by year 9.

  1. From my graphs I can see that when looking at the whole schools height and weight I can see there is a positive correlation.  I then broke the school up into upper school and lower school.  In these graphs you can notice that there is also a positive correlation.
