## My hypothesis’s

My hypothesis is to see if there is a difference between two ages estimating angle and length is different. I also think that people are better at estimating lengths than angles.

Also to see if males are better than females at estimating the length and angle.

And if playing sport helps at estimating lengths and angles.

I think that the older people are better at estimating angles and the length because they have more experience at doing so from further education and more experience.

I also think that the male sex will be better at estimating this better than the female sex because they play more sport and have to judge lengths and angles more of the time e.g. football, basketball, rugby.

I have done a pre test to make sure that my main experiment will work by cheeking the method and data collection sheet

For all three of my experiments the length of the line and the degrees of the angle will be the same the length will be 4.5 centimetres and the degrees of the angle will be 36 degrees

## Plan

#### I will collect data from year 7 and year 11 boys and girls

To make sure it will be a fair test by making sure the subjects have the same amount of time to estimate the length of the line and the degrees of the angle. Making sure the angle and the line are all the same place on the paper and are the same colour and that the distance from it is not varied.

The experiment will be consisting of an overall sample of 120 people divided into 30 male, 30 female, and 30 students in year 7 and 30 male and 30 female students in year 10 all these people will be extracted at break times during the school day and chosen at random. A scientific calculator does this.

If I had a sample of 30 people 15 female and 15 male and I wanted to choose 8 of them 4 male 4 female I would use my calculator Ran# button on my calculator, this is how I did it I got hold of a sample of 30 people.

Sample of 30 people:

I then did this equation on my calculator:

(The equation may vary form calculators)

## 2ndF RAN X 30 =

I pressed = symbol and my calculator came up with a random number between 1 and 30

I rounded that number to the nearest 10 and underlined that number on my sample the first 8 went like this:

1. 2ndF RAN X 30 =16.86 = 17 M

2. 2ndF RAN X 30 =28.44 = 28 M  the first 4 males Rad# chosen

3. 2ndF RAN X 30 =24.12 = 24 M  will be the ones that will be in the

4. 2ndF RAN X 30 =14.91 = 15 M  pre test.

5. 2ndF RAN X 30 =13.56 = 14 M

6. 2ndF RAN X 30 =12.39 = 12 F

7. 2ndF RAN X 30 =15.33 = 15 M this one has been used once so we ignore it.

8. 2ndF RAN X 30 =22.86 = 23 F

I then underlined the ones that had been randomly chosen:

I had to do this 5 more times to get 2 more F for the pre test

1. 2ndF RAN X 30 =16.23 = 16 F

2. 2ndF RAN X 30 =13.74 = 17 M

3. 2ndF RAN X 30 =16.32 = 16 F this one has been used once so we ignore it.

4. 2ndF RAN X 30 =15.75 = 16 F this one has been used once so we ignore it.

5. 2ndF RAN X 30 =4.2 = 4 F

### The first 4 females are the ones that will be put in to the pre test.

You cannot have the same number twice because you would be asking the same sample twice so you would get the ...
