#### 'Used Car Prices'

USED CAR PRICES - coursework My coursework is based on 'Used Car Prices'. We have to investigate on what influences the price of a second hand car. Hence my task for this assignment is to statistically analyse the data given concerning 2nd hand cars. I shall begin with looking at the data and then deciding on what graphs to present. There are a number of ways of representing data diagrammatically thus I have decided that I will use scatter graphs. Here is a description of what Scatter graphs are used for: Scatter graphs are used to solve real life problems mathematically and obtaining relationships between two sets of data. This is called mathematical modelling. A line of best fit is drawn, which should pass through as many points as possible. It should have approximately the same number of points above and below it. The less scatter (separation) there is regarding the best-fit line, the stronger the relationship is between the two quantities. There are two types of correlation: positive and negative. If the points are close to the best-fit line, we say that there is a strong correlation. If the points are loosely scattered, there is a weak correlation. There is no correlation if there is no trend in the results. I am going to begin my coursework by firstly collating the data I need and then deciding on what variables I will include in my tables and graphs. Here

#### Used Cars Price - Mathematics - Use the information to investigate what influences the price of a second hand car.

Used Cars Price Mathematics Use the information to investigate what influences the price of a second hand car. Introduction: The assignment I have been set, is to investigate what influences the price of a second hand car. I will complete the assignment, by interpreting the information of 100 cars that I have been given, also taking into account what categories are best to use when buying a second hand car. The method I will be using to find out what influences the price of a second hand car is; The random selection process. The random selection process is the best method to get this type of data organised, as it can randomly chose 30, or how ever many cars you want work with. This process requires the use of a calculator, so the data can be randomly chosen for us to then move on to interpreting it.

#### Gary’s Car Sales

Gary's Car Sales Aim The aim of this assignment is to find out what factors affect the second hand price of cars. Hypothesis I think the second hand price of a car mainly depends upon two of the three factors of age, mileage and engine size, but also other smaller factors such as central locking and air conditioning etc. For this assignment however we were only asked to concentrate on information that we were given such as the age, make of car, mileage and engine size. To test if my theory is correct I will make an equation that will tell me the second hand price of a car if I input certain characteristics like the age and mileage. To do this, I will first have to plot scattergraphs and create equations from them first before making the overall equation for everything. Method To find out which of the factors made the most difference, I made scattergraphs on each factor against the second hand price, with a line of best fit to help show correlation's and to help create a formula. All the information I needed I found from a "Gary's Car Sales" information sheet which was provided by our teacher. This sheet provided information on the 2nd hand price, the age, the make, and the price when new, the mileage and the engine size in litres for each car. Each of the scattergraphs have a line of best fit with the formula of a straight line drawn on, with substituted letters to

#### The Ford motor company and the Pinto Gas Tank: A case study in corporate ethics

THE FORD MOTOR COMPANY AND THE PINTO GAS TANK: A CASE STUDY IN CORPORATE ETHICS 5/3/2004 PURPOSE The decisions and actions made by management leading up to and following the introduction of a product into the marketplace affect all the stakeholders involved in some fashion. As would be expected, some decisions are more important than others due to their nature and impact on the parties concerned. The purpose of this paper serves to understand and evaluate the ethics behind the decisions made by the Ford Motor Company with respect to the Pinto car model with an emphasis on the ethics surrounding the safety of its gas tank. SCOPE To accomplish this purpose, this paper will review the life cycle of the Pinto and the decisions the Ford Motor Company made with respect to the safety built in to this vehicle. Therefore, the time period in question will be between the years of 1967 thru 1980 thus covering the design, development, market introduction and market withdrawal for the Pinto. The government regulations or lack there of, placed on the automobile industry during this time period will also be discussed to add some perspective as to how thin of a line the Ford Motor Company walked when making some of the decisions regarding the Pinto's gas tank. APPROACH The three principle elements of social responsibility (externally mandated actions, market actions and voluntary

#### Investigation into the factors, which affect the value of automobiles.

Handling Data Coursework Lines of Enquiry I have chosen to conduct my investigation into the factors, which affect the value of automobiles. There are many factors, which I could investigate, and I have chosen to choose my line of enquiry from the following list; * The Mileage of the cars * The age of the cars * The size of the cars * The make (manufacturer) of the cars * The number of previous owners * Whether or not it is taxed/MOT'd Hypothesis Does the size of a car affect its second hand value? Do smaller cars hold their value better than larger cars? I think that smaller cars depreciate at a far slower rate, and so are worth more of their original value than larger cars. To prove this, I will calculate the depreciation of small cars and large cars (averages) to test my theory. I will exclude anomalies such as Rolls Royce and Bentley as they are too expensive and their engines are so large that they will not fit a sensible scale. I will group the cars by engine size, large (>1.4L) and small (£1.4l) and calculate the average percentage of depreciation each year. Also, I will end the group at 2.5l as after this, I believe that the information will become disproportionate and so anomalous due to the shire size and fact that such automobiles would usually fall into another category or rate of depreciation. I could later expand my investigation to include

#### Investigate what influences the price of a second hand car

Aim Use the information to investigate what influences the price of a second hand car. Introduction I'm going to find out what it is that affects the price of a second hand car. Hypothesis I think that the main factors in the drop of car prices are the age and mileage; this is because they give us a good indication as to what the cars price and other information could be. Plan I am going to prove this by making scatter graphs which compare the age and mileage with the second hand price. I have decided to only use 3 car makes, this is because there is 100 different cars with lots of irrelevant information. Therefore I will use Ford, Vauxhall and Rover because these are the most popular makes in the database. The data I am goin to use is the price when new, second hand price, age, mileage and finally I am going to work out the difference between the price when new and second hand price. Scatter Graphs I have decided to do scatter graphs instead of different graphs because of the line of best fit. Using line of best fit means I can predict other information on cars where I havent been given all the information.

#### Investigation of factors that effect the price of a car.

Investigation of factors that effect the price of a car Introduction: For this investigation I will be using the data to investigate what factors influence the price of a second handed car. To do this first I will specify clearly what I am going to do and why I am going to carry out the investigation this way. Then I will collate the data that I need and represent it in a way that helps me to develop my investigation. Finally I will interpret my results and draw conclusions from them. I'll be using tally, Bar charts, cumulative frequencies, frequency charts, scatter graphs and Pie charts. Planning: First I shall provide the data all the cars that will show Price Vs Mileage, Price Vs Age, car ownership and number of cars per model. After that I will pick out the top 3 cars which reappear the most in the charts and graphs. After that I will examine the Price Vs Mileage, Price Vs Age of those 3 selected cars. I will then see what factors or what qualities do these cars have which are affecting there price and popularity for e.g. Mercedes may not be owned by that many people because it is a prestige car and has all the qualities, it still holds its price. The reason for car ownership could be that the Mercedes might not be affordable because it is too expensive for some people or isn't affordable. After doing so and once I have examined the factors affecting each of

#### Investigate how the prices of used cars vary from new cars.

USED CARS PRICES PLAN I am going to investigate how the prices of used cars vary from new cars. I am going to sample all the cars that are two years of age and under and compare it with cars that are in the range of five to eight years old. I am going to compare two different cars makes with each other and I am also going to sample out all of the cars with the mileage of 70,000 and less and compare it the price of the cars with the mileage of more than 70,000. I will plot the prices of cars on different graphs, draw a line of best fit and compare it with the others. So I will have three different types of graphs that are going to be age against price, make against the price and mileage against the price. I collected the following data for my coursework: No. Present Price Price when New Age Make Mileage Engine Size £6,970 £11,600 3 Ford 24,000 .6 2 £3,350 £7,100 7 Peugeot 85,000 .1 3 £3,995 £13,800 6 Ford 52,000 2.0 4 £5,300 £16,300 6 Vauxhall 70,000 2.0 5 £6,500 £8,700 3 Fiat 24,000 .2 6 £1,500 £8,700 9 Vauxhall 82,000 .6 7 £995 £8,500 9 Ford 02,000 .8 8 £3,000 £10,400 7 Vauxhall 63,000 .7 9 £7,495 £9,770 Vauxhall 8,000 .4 0 £850 £7,540 0 Ford 24,000 .6 1 £5,595 £11,000 4 Ford 41,000 .6 2 £4,995 £9,880 3 Ford 34,000 .4 3 £5,595 £14,000 4 Ford 55,000
