Statistics Project

Statistics Project

I have been given instructions to collect data for my GCSE statistics

coursework and then to represent them by interpreting them using

graphs and attributes, which I think influence the prices of a second

hand car. Below is my coursework flowchart that will show the steps I

will take to complete my coursework.

HYPOTHESIS

I think that the age, make, amount of owners will affect the price of

the second hand cars. In the investigation, I will use several

different types of charts and graphs to support and show my hypothesis

is correct and to show if my predictions were incorrect, or correct.

After I have investigated some of the attributes, I will then draw up

another hypothesis and see what will happen at the second half of my

investigation. I think that if things do change, the tax amount and

mileage may affect the price.

DATA COLLECTION

---------------

There are many types of data, to obtain it we must observe and measure

something. This is known as a variable, there are two types of

variables:

-Quantitative variables, which have NUMERICAL observations or

measurements.

-Qualitative variables, which have NON NUMBERICAL observations or

measurements.

The other types of data I may consider using are

Continuous data which are measured on a scale and can take any value

on that scale

Discrete data which is concerned with a number of countable values.

Collecting data

Two types of data used can be Primary data and secondary data.

Primary data is data that is collected by or for the person who is

going to use it. Secondary data is data that is not collected by the

person who uses it.

Data can be collected using an experiment of survey.
