Testing a Hypothesis about Male and Female Drivers

My initial thoughts on the data are that it seems that more females

are taking driving lessons than males as seen in the pie chart below.

It would also seem that as the number of 1hour lessons increases the

number of minor mistakes made decreases. Instructor B looks to be the

most popular as he is chosen the most out of the four. I am going to

state 3 hypotheses based on this data and am going to use my

mathematical knowledge to support them.

Hypothesis 1: Females make more Mistakes than Males

For this hypothesis I decided to choose 60 pieces of data from the

sheet, 30 pieces that are male and 30 that are female. I used the

random number button on my calculator and multiplied it by 240 (the

total pieces of data) this insures that the number is between 1 and

240, the number that comes up must be rounded to the nearest whole

number this number is then used to pick the relevant number from the

sheet. Once 30 pieces of data had been collected for the males and I

had not yet got 30 for the females, I continued using my calculator

until I got a number that corresponds with a female piece of data on

the sheet. Once I had 30 for each I started to refine the data.

I started by taking the 30 male pieces of data and 30 female pieces of

data and plotted them on a line graph seen below.

From the line graph I found that it was a male who made the highest

amount of mistakes but also a male who made the lowest amount of

mistakes. By looking at the graph I also found that a greater number

of females were found to be greater than that of the males.

I then proceeded to make 2 cumulative fr...

... middle of paper ...

...5 + with a

few exceptions this shows that females overall are making more

mistakes than males.

I also did a stem and leaf diagram which shown me that most males were

making few mistakes and the bulk were in the regions of 0-20 whereas I

could see that only one females scored from 0-10 and a bulk scored

from 10-30 which is a bit greater than the range of the males

indicating that the females are making more mistakes than the males.

From this hypothesis the evidence that has been shown clearly supports

my it, but against it could be argued that on a Friday the traffic is

greater because of all the people rushing home and so the traffic

affects the amount of mistakes made. Also it could be said that maybe

its because males have had more 1 hour lessons before they took the

test which is why they make lees mistakes.
