Introduction

Handling Data

In this investigation I am going to be Data Handling and do a comparison between height and weight. I will use a random selection of students from Mayfield School with 15 girls and 15 boys.

The first thing I will do is choose the students and to do this I will use a calculator and as there is 1183 students I will use the sum:

1183 x RANDOM = STUDENT NUMBER

Here are the students:

F        1.52        45

F        1.57        52

F        1.52        45

F        1.79        43

F        1.63        38

Middle

1.41 - 1.5        IIII        5

1.51 - 1.6        IIII III        8

1.61 - 1.7        IIII III        8

1.71 - 1.8        IIII I        6

1.81 - 1.9        I        1

1.91 - 2.0        I        1image00.png

There are very few people in the sample who are smaller than 1.41 metres and taller than 1.8 metres. Also by our sample it suggest that at Mayfield High School there are likely to be fewer people who are between 1.3>1.4 or 1.81>2.0 metres than other heights.

Now I will tally the weights of these pupils:

Weight        Tally         Total

26>30         I                  1

31>40         IIII IIII         9

41>50         IIII IIII       10

51>60         IIII              4

61>70         III               3

71>80                            0

81>90         III                3

As you will see by the tally the most frequent weight is the range between 41>50

Conclusion

Now I will try this hypothesis on the Males:

Males Height

Range 1.30m– 1.97m

  1. 1
  1. 1
  1. 3
  1. 5
  1. 3
  1. 1
  1. 1

Males Weight

Range 26kg-84kg

  1. 1
  1. 5
  1. 2
  1. 2
  1. 3
  1. 0
  1. 2

Now I will put them into a table:

Now I have these graphs I see that there could be a change for the boys as the smaller you are the heavier you are.image04.pngimage05.png

Now I will compare the heights of both males and females in a graph:

This graph shows that males tend to be taller than females.image06.png

Now I will see who is the heavier of the two:

This also shows the males are heavier than females.image07.png

To conclude my investigation you can see by the results that the males seem to be heavier and taller than females.
