Investigation Into Students' Ability to Estimate

We have been given a task to work with the statistical side of maths.

We were told that a random sample of one hundred and fifty people were

asked to estimate the degree of an angle which looked like this:

Also each person was asked to estimate the length of a line which

looked something like this:

[IMAGE]

From this we were asked to think about what sort of conclusions we

could give for the analysed results. I thought about this and came up

with the following hypothesis:

"Males in the 11-18years age range will guess the angles and lengths

better than females in the 30+years age range."

I have chosen this hypothesis because it allows me to look at both age

and gender of the surveyed people.

(The actual measurement of the angle was 36.5degrees and the actual

measurement of the line was 4.35cm)

The data I have received from the survey is on the following page…

PLAN:

To investigate this hypothesis I may need to use a number of methods

to calculate the data I will receive. I may need to use many

statistical tools which I already know; such as Averages, Standard

Deviation, Frequency Polygons, Histograms, Scatter Diagrams,

Cumulative frequency and maybe other methods which I will have to

research.

As the sample I am being given is random, it has a large range of

varied aged males and varied aged females. I need to divide the groups

up into the groups I have to work with according to my hypothesis.

Hare are the divided groups from the data:

Males aged 11-18years:
