GCSE STATISTICS: COURSEWORK

'WHAT AFFECTS A PERSON'S ABILITY TO ESTIMATE?'

Aims, Design and Strategy

This investigation is all about finding out what affect's a person's ability to estimate. To answer the question to its full extent, I need to investigate thoroughly and be precise. My aims for this investigation are:

- To record what factors affect a person's ability to estimate and to what extent.

- To investigate the chosen variables in depth, to ensure an accurate result is made.

The strategy for completing this task will be to simplify down the investigation into different areas. From doing this I can investigate in more depth. I hope to achieve a conclusive set of results to show which variables affect a person's ability to estimate.

My hypothesis of this investigation is that

Middle

The variables which might affect a person's ability to estimate could be:

- Age: does a person's age affect their estimating ability? Getting hold of older people in the same quantity of 11-18 year olds could be a problem.

- Intelligence: how do we actually calculate intelligence? An average children's intelligence I could record from their maths sets, but what about people older than 18?

- Gender: does being male or female mean you have a greater ability at estimating?

- Occupation: does being a chef mean you have a better estimating ability?

The variables which I could use for estimating are:

- Length: For this I could ask a number of people to estimate a specific length.

- Weight and Mass: For these I possibly could give someone an object and ask him/her to estimate the weight.

Conclusion

When I begin designing the data collection sheet I will have to ensure that the task they are doing is clear and well laid out.

On the sheet there would need to be space to put:

- their age, the full question, space for their answer.

A number of problems could occur, such as:

- cheating: a ruler could secretly be used when I look else where for a moment.

- rules: does the task need rules? Does there have to be a time limit?

Can these problems be overcome? If so, how?

For cheating: I would have to make sure the person didn't have any rulers or equipment on them to find out the actual length.

For rules: I would give a time limit of 30 seconds. I would use a watch to time the estimation. The rules I'd set would be to not cheat, but simply estimate to your full ability.

    Upper quartile is 27,500. So the interquartile range would be 27,500 - 23,900 = 3,600. The interquartile range shows the lower and higher quartiles are within 3,600 of each other. This spread shows a greater spread of data, meaning the data is more varied and less consistent, it is also a shows the attendance

    Finally, when investigating my hypothesis I have to remember factors that may affect my conclusion. One such factor is age. Therefore with every graph and diagram I will draw one for year 7's data and one for year 11's. This way age will not affect my conclusion and I can also look at how age affects IQ as well.
