Statistics Experiment

For my maths coursework I will be conducting an investigation into
statistics. I had a choice for this coursework of both statistics on
year 10 to 11 school children, and facts about them and also their
likes in terms of sport and subjects at school. I chose not to do this
project on that information; instead I chose data on 100 different
cars, the reason for this is that I like cars more and may perhaps
pursue it as a career. I did not want to do a project on data that I
have no interest in.

The 100 different cars have data under the following headings, Car
number in order from 1 to 100, the make of the car, the price when new

For my coursework I will be hopefully conducting a total of 3
different investigations into this survey, though this may change to 2
or 4. My aim is to look for a correlation in the separate
investigations and perhaps if I can draw any conclusions or maybe find
a formula or prediction for a particular investigation that will work
for all or most cars. E.g. if from mileage, price when new and age I
can calculate the current second hand price.

My investigation will be:

The frequency of mileage in my sample, if there is a relationship
between the second hand price and age of a car, and finally if there
is relationship between the age and percentage loss of a car.

I will be taking a sample of 20 cars; I will take every 5th car in the
database. I will show the data in terms of tables, a tally chart, and
by way of bar, and scatter graphs with a line of best fit if
applicable.

To improve my investigation I will take a sample of 5 cars, which will
not be included in my final investigation, but this 5 car sample is to
test my investigation techniques, and to allow me to foresee and
problems and practise in investigating statistics.

I will not be able to take all 100 cars and will have to do my
investigations on different samples of the survey, I hope to take 1/5
of the cars, and I will do my investigations on 20 cars. I…
