Now I am going to sample out the cars that are 2 or less years of age, and compare them to the cars that are in the range of five to eight years old.
Below are the cars that are below the age of two:
Below is the graph showing the price against the age.
This graph shows a negative coloration, it shows that as the car gets older than the price goes down.
Below are the cars that are in the range of 5-8 years old.
Below is the graph showing the price against the age.
This graph also shows a negative coloration and it also shows that as the car gets older the price goes down.
The trend line in this graph is steeper than the one on the top; this is because the cars’ price doesn’t drop so much while it is a couple of years old, where as after a few years the price of the cars goes down quicker.
Now I am going to sample out cars according to their make and then chose two of the most common ones, then I am going to compare the prices of the two car makes.
As you can see that the two most common car makes are, Ford & Vauxhall. There are 12 Ford cars & 9 Vauxhall cars. So now I am going to make graph and compare both of them.
Vauxhall Cars
Here as you can see that there is negative coloration, in the graph, it shows that as the car gets older the price of the car goes down. There is one exceptional result, and that can be because of the model. Other than that all of the other prices are very close to the line of the best fit.
Ford Cars
Here as you can see that there is negative coloration, it shows that as the age goes up the price of the car goes down. There is not any anomalous results in this graph this shows that all ford cars used for this database have got similar price. This graph shows that the ford cars are cheaper than the Vauxhall cars.
Now I am going to sample out the cars according to their mileage, I am going to sample out the cars with the mileage of 0 – 69,999 miles and compare it with the cars with the mileage of 70,000+.
Below are the cars that have the mileage of 0 – 69,999 miles.
Here as you can see that this graph also has got a negative coloration, the graph shows that as the mileage goes up the price goes down. There are two anomalous results; this can be because of the model of the car. According to the graph the cars with the least mileage have got the highest price.
Below are the cars that have the mileage of 70,000+
This graph is not as I had predicted it to be, it has got positive coloration where as I thought that it is going to have negative coloration.
