Investigating Students' Measuring Skills I have decided to test a group of pupils in order to investigate if

there is a difference in ability to estimate the size of an angle and

the length of a line. The factors that can be looked at are as

follows: -

· Set

· Gender

· Location of line / angle

In order to test all these factors I will need a range of pupils

selected at random from a range of sets. I have decided that 18

pupils, selected from three sets will be appropriate for my

investigation. I will select 6 pupils, three male and three female,

from sets 1, 3 and 5. The quota of eighteen pupils I will use from the

sets will give me an appropriate, representative sample.

Since there are three different ability sets of pupils (sets 1, 3, and

5) that are to be tested, with a wide gap between them I should be

able to see clearly from any graphs and tables I draw any results

trends or patterns which may suggest that the intelligence of a pupil

does affect there ability to estimate the length of a line and the

size of an angle.

I have selected an even number of male and female subjects for my

investigation with the same number from each ability set of pupils,

using this information and results I collect I should be able to draw

conclusions upon whether the sex of a pupil determines there ability

to estimate the length of a line and the size of an angle.

I aim to also see if the location of the line or angle determines a

person's ability to estimate the length of a line or size of the

angle. I propose to do this by placing various lines and angles within

shapes, i.e. is it easier to estimate the circumference of a circle or

the length of a straight line, to see if this deceives the test

subject or makes it easier.

In order to carry out my investigation I will have to prepare a test

sheet of various angles and lines to present to each of the pupils in

each of the sets. I will also require a results table in order to

record my findings. I have decided that five different lines and five

different angles would be sufficient to draw suitable conclusions

from, for testing whether the location of the line or angle determines

how easy it is for the pupils to estimate them. The five lines I will

use will be: -

· A straight line

· One side of a triangle

· A randomly shaped line

· A circle

· A zigzag line.

I think that these lines will be sufficient enough to be tested. The

variety of lines will help me later with making conclusions about the

investigation.

Predictions

I believe that the lower down the set the person is in the less

accurate there guesses as to the length of the line or the size of the

angle will be. I think this as people in the higher sets are more
