Guessing in Geometry

Guessing in Geometry

Hypothesis

1- I predict that if people are good at guessing the length of a line

they will be good at guessing the degrees of an angle.

2- I predict that the higher the schooling year the better the

estimate.

Target population

I have decided to investigate within the schooling ages of 7 and 9

firstly because these are easily available to collect due to having

timetables and knowing where all the students will be when needed to

guestimate. Another reason for picking students between these ages is

that it is a big enough variety to draw conclusions from, and decide

whether the amount of school really does improve the ability to guess

the size of a line or angle. I will not be asking every year group as

this will take up too much time and will not be necessary. I will be

asking years 7, 9 and 11 this gives a big enough range of the amount

of school experienced without asking every year.

Study Population

I have chosen to get a list of the students in years 7, 9 and 11 and

then ask every fourth person on the list this will the give a quarter

of each year being asked which is enough to draw conclusions from. I

am not going to ask everyone in the three selected years because this

would take to long and it is not compulsory to get the information I

need.

Aims

I will prove my hypothesis true or false by asking the selected people

to guess the length of a line or size of an angle and then find the

mean median mode for each year and draw graphs. I will also draw a

graph relating their guess of the size of an angle to their guess of

the length of a line.

To gain fairly accurate results we will not let the pupils take the

sheets away whilst guessing we will stay with them so there is no

chance of using a rule or protractor.
