Used second hand cars
Introduction: I have been provided with a set of data, which altogether includes the factors that affects the second hand car prices of the listed hundred cars. Such as *Age, *Mileage, *Owners, *Insurance group and *MPG to name a few. You will see a spread sheet of this information on the following pages. My task is to relate the prices of the second hands to number of variables. Also so how and state why they are important elements. I must then interpret my results and finally come to conclusion from them. Many problems of statistical nature are made clearer when they are put in the forms of hypothesis. A hypothesis is generally considered to be a statement which may be true, but for which no proof has yet been found. I am going to choose o less than three factors, which I feel has an affect on the prices of the second hand cars. To start my project I have come up with three responsible questions, which I believe, could help me with my investigation. The questions I have decided to experiment are: . Does the age leave a huge impact on the second hand value? 2. What about make? Would you rather spend more money buying a cool car rather than buying a new car which is cheaper and less stylish? 3. How many people care about the mileage? Is there any disadvantage to the mileage? From the alternative data base given to me I will randomly choose 3o cars and separate them
Used Cards - find which factors will influence the price of a second hand car and in what way
Maths Statistics - Used Cars Pilot Study Aim The aim of the coursework is to find which factors will influence the price of a second hand car and in what way. I believe that the price second hand cars are sold at is dependant upon several factors; certain factors will have a much larger effect on the price than others. In my investigation I am going to chose the two most popular (this being the most amount of a specific make provided by Edexcel of two specific makes) manufacturers of cars from a tally chart of all of the cars because the thing that people look at first when they are buying a car is the make and I believe this is what will affect the second hand price also. Different makes have different prices and depreciate every year at different rate resulting in sum cars holding their value due to the make. In addition certain cars have a very good reputation of being reliable while others are not. Also some cars have a higher social status than others for example people would prefer a Mercedes over a Ford. Before I commenced with developing a hypothesis, I firstly explored and tried to discover any data, information or details needed for my statistic coursework. Previous to this, I was given a candidate sheet that provided me with factors which I may have liked to consider. The factors are: * Price * Age * Mileage * Cost when new * Engine size * Colour *
The aim of this investigation is to find out what influences the price of second hand cars.
MATHEMATICS COURSEWORK: Statistical data Use the information to investigate what influences the price of a second hand car Aim The aim of this investigation is to find out what influences the price of second hand cars. (used cars) Introduction Hypothesis The sample provided, includes a list of 100 cars that shows quantitative and qualitative data, such as Second Hand Price, Engine Size and Colour. To obtain my hypothesis, I carried out research in a car magazine called 'LOOT' and a website: www.autotrader.co.uk From this I found out that the most common cars reflected my sample and this was also a good indication of cars on the current market today. The magazine and website research gave me quantitative results. Therefore, my hypothesis and what I will investigate from this is: "The older the car in age and the more owners it has, the more cheaply the second hand price value is going to be." Also, I take into consideration that, "The less mileage the car has, the better condition and more expensive the car is. This more mileage the car has, the more likely chance of it being a cheap, second hand car." I chosen this as my hypothesis because, in reality that is what determines the price of car, For example, If a new car in age had a lot of owners, it would vary the second hand price of the car. This is compared to a the same car, but with fewer owners, it
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
Factors affecting price of Used Car
Introduction I have been given a coursework with secondary data that contains different types of car makes, each with different models. The data has all the mandatory information of a car. These are; colour, age, mileage, engine size, both price when new and price when used. My objective is to find out which of the factor/s mentioned above has/have the most effect on the price of a used car. Hypothesis A car is considered to be used when it has been travelled with. Travelling consumes time and consequently increases the mileage of a car. I therefore predict that the older a car gets, the more distance it covers and hence undoubtedly the less it will cost in the market. Method of Enquiry I am going to carry out an investigation applying all my mathematical and general knowledge to analyze and find out the factor/s affecting the price of a second hand car. Since the data I have is of two types i.e. Qualitative data (involves names and words e.g. black, blue, yes and no) and Quantitative data (involves numbers and figures), this makes it very complex to work on. I will refine my data so that I will work on only the major factors, which affect most and then later on I will break them further into small bits so that I will remain with a maximum of two factors. The reason for doing this is because some of the information contained in the data is hardly of any use to help me
Objective; to investigate the relationship between used car price and age of car.
30/6/03 Mathematics Coursework C+H/WK Objective; to investigate the relationship between used car price and age of car. Equipment; to do this task I will need the following equipment; Ruler, Pencil, Pen, Multimedia computer (to write up investigation in neat), And plenty of A4 paper. My Hypothesis; Since all the cars from the given data base are MODERN cars, I predict that they ONLY decrease in value once they are bought. It would be different for really old CLASSICS as they can be so old that they actually increase in their value as they age. This is because; . The demand of these cars rises as few are left available, from being scraped. 2. Since theses cars lack modern technology of galvanised metal, they suffer from rust, thus people selling them in mint condition spent thousands of pounds restoring the car to it's original condition, hence they want that money back when they come to sell it. 3. The cars are different from modern cars, and give the owner a high status through being so immensely unique. Because all these cars in the database are all modern, the cars should, in my prediction decrease in value as they age and those that are guaranteed to become classics may depreciate slower in value than those that aren't. Also those of luxury and

Maths Coursework - Used Car Data Investigation Plan In this project we have been given a large amount of data on used cars to work with, and our aim is to analyse this and investigate any possible correlations between cost and other factors given. Brainstorm I have brainstormed all the possible factors affecting the cost of a second hand car below. From these I will select 3 in which to study in detail. * Mileage * Age * Condition * Fuel * Make * Air conditioning * Insurance group * Number of owners * Engine size * Service * MPG * Central locking * Length of MOT * Airbags I will be investigating mileage, age and make of car, primarily because it is easy to gain extra data from other sources on these three, but also because there are possible correlations not only with cost, but also between the three factors I have chosen. Hypothesis I have a number of hypothesise which I will explore in this project: * As mileage increases, the price of the car will decrease * As age of the car increases, the price of the car will also decrease * The make of the car will carry higher or lower prices depending on the make; some makes will cause prices to be higher, others will cause prices to be lower. What I will do in this project To begin with, I will look at the list I have been given in a general manner, by conducting a brief search through the list, looking at
