Introduction

I have chosen to look at the connection between, height, weight, intelligence quotient (IQ), hours of TV watched per week, and Key Stage 3 Sats results. I am hoping for a strong connection between either height and weight and weight and IQ. I have chosen these because I think it will be interesting to see if the amount of TV watched does affect your weight because of being inactive for long periods of time. Also I would like to find out if people with higher IQ’s don’t watch as much TV as people with lower IQ’s.

#### ➔ Aim

My aim will be to investigate the following statements:-

1. Year 11 students are heavier and taller than Year 10 students
2. The higher the intelligence quotient (IQ) the higher the Key Stage 3 Sats Results.
3. The more hours of TV watched per week, the lower the intelligence quotient (IQ).
4. The more hours of TV watched per week, the more the student weights.

#### ➔ Hypothesis

1. I expect that the investigation of year 11 students being heavier and taller than year 10 students because as year 11 students are older meaning they would have started puberty before year 10 students making them taller and heavier.
2. I expect that the investigation of the higher the intelligence quotient (IQ)

Conclusion

#### ➔Evaluation

In order to make this investigation more accurate and reliable I could have used a much bigger sample. Although this would involve a lot more time being spent and more calculations, the accuracy of the investigation would be much better and this may show and even stronger correlation and even proven my entire hypothesis correct. However, I have only looked at a sample of the data, the sample was taken randomly and I have not been bias at any time throughout the investigation so I do believe that my conclusion is correct and that there is a strong correlation between height and weight of pupils in year 10 and in year 11 and between the IQ and Average Sats Scores.

I could also carry on the investigations by going into the genders by investigating that year 11 boys are taller and heavier than year 10 boys.

Overall as a conclusion I have fulfilled 50% of my aim and have done so fairly with relatively accurate results, overall the investigation was quite successful.

1. ## Maths Statistics Coursework - relationship between the weight and height

I drew a line of best fit to show me this correlation. There are a few anomalies in the graph, however the two mean lines for the height and weight indicates me the average point of both variables. Most of the points are clustered in that area which tells me that most of the points is around that mean average.

Comparing Male to Female Gender has many different areas which can be covered. I'm starting off with simply comparing all the males to all the females: MEAN AVERAGE STANDARD DEVIATION MALE 9.16CM 2.59 FEMALE 8.57CM 2.14 From this table, I can see that all females are better at estimating then all males.

This will mean more energy is given back out when the ball rebounds meaning it will bounce higher. There is intermolecular friction inside the ball that means the ball will lose some heat energy (this should stay constant if you use the same ball) but it is not very significant.
