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
of the car, the current second hand price, the age of the car, the
colour of the car, engine size e.g. 2 litres, the type of fuel the car
uses e.g. diesel or unleaded, the MPG (miles per gallon) this is
roughly how many miles the car can travel at a constant speed on one
gallon of fuel, the current mileage of the second hand car, if it has
a service history or not, the number of previous owners, the length of
the current MOT (road tax) if there is one, the TAX months, its
insurance groups (this relates to the prices the owner will have to
pay to insure the car, e.g. a high insurance group costs more money to
insure), the number of doors (including the boot door), the style of
car, if it has central locking or not, the type of gearbox and if
manual the number of gears, if it has air conditioning, and finally,
if airbags are included.
There are 23 different headings under which data has been entered, and
there are 100 cars in this survey. Using this information I can make

1. I think that the more mileage, more owners, and older the car, the
less it will be able to sell. The percentage loss in price of each car
will be higher relating to the higher the three factors are (mileage,
age, owners). I hope to draw up a formula from this, to calculate the
re-sale price of cars given the three factors. I feel there will be a
strong relationship between the percentage loss of a car and its Age,
but perhaps a weaker or no correlation between the second hand price
and age of the cars.
When comparing cars, I will have to insure my investigating is fair,
by only sampling cars that are exactly the same or have a few minor
differences, I cannot compare the re-sale price of a Ford and a
Bentley, as the Bentley will be a higher price if though it is older.
In the experiment “ Talking to plants “ from Mythbusters, potential problems include the use of greenhouses with no sound insulation, a non-homogeneous location and the use of only one specie to infer on a population. In another scientific study, researchers chose to use “ a noiseless growth chamber to prevent any effects from extraneous noise “ and the use “ growth chambers under continuous light at 28 c and 65-75% relative humidity “ in order to maintain a homogeneous location for all plants during the experiment (Jeong et al., 2008) . This helped further explain the findings because with the use of noiseless chambers you can assure that the only noise that the plant was receiving was the one given in the treatment and a valid conclusion
dealers faced a loss of more than $100,000 worth of cars, which were struck by
The automaker Chevrolet has experienced much technological change in the past 104 years. Although it, Chevrolet, is a French name, it is an American car company. It was primarily founded by William C, Durant, along with Louis Chevrolet, on November 3, 1911. It wasn’t until six years of existence that it became part of the Automotive Division at General Motors, otherwise known as GM. Durant had previously tried to buy out Ford and failed. This caused him to resort to co-founding Chevrolet. The first car sold by the company commonly called Chevy was the Classic Six, at the price of 2,500 dollars. Chevy started producing these vehicles in 1912-1913. The car’s value may seem like pocket change but that is the common day equivalent of roughly 57,000
The first observation from the financial data in appendix one is that General Motors has a low profit margin and is generally less than the industry average each year. The firm is able to keep a low profit margin because they have such high sales volumes throughout the world. This strategy can be both an asset and liability in business planning. The plus side of the strategy is that GM is able to sell a large number of vehicles in the marketplace due to the lower selling price as compared to the competitor. However, the down side of the strategy is that there is a possibility that if sales volumes decrease, the firm can incur a significant decline in the EPS because the profit margin on each item sold is very low. If the global economy sours, GM can have a very difficult time meeting shareholder expectations.
Introduction: The purpose of this laboratory activity is to investigate the Hardy-Weinberg Law of Equilibrium using the fruit fly Drosophila melanogaster. According to the Hardy-Weinberg Law of equilibrium, allele frequencies should remain the same in large populations that do not experience gene flow, mutations, nonrandom mating, and natural or artificial selection. We will be studying the alleles that determine wing shape, either normal (wild type) wings or vestigial wings.
However, this calculation is incomplete because the company needs to take on debt to finance the purchase of the car. These payments add an additional expense and cash outflow but purchasing still remains a more attractive option. The cost of the lease is still greater than the cost of debt.
n hypothesis of the experiment is that the group containing four members will perform better than the group containing two members. This is the foundation from which we have conducted our experiment.
A researcher determines that 42.7% of all downtown office buildings have ventilation problems. Is this a statistic or a parameter; explain your answer.
In a capitalistic country with a free market, foreign competition is expected. This is no exception for the automobile industry where America competes with its various rivals. Competition from elsewhere encompasses that from Italy, Germany, and of course, the renowned Japan. The Japanese vehicle industry is especially competitive; according to the Automotive News Data Center, five out of the ten best selling vehicles of the year are Japanese vehicles. This data applies to the U.S. market over the first 9 months of the year. Expectedly, the automobile industry is an important and significant market. Motor vehicles are a major form of transportation as many people in the U.S. own at least one car.
For this research requirement I chose three different experiments to examine thoroughly. The first of these experiments came from the Journal of Experimental Child Psychology. The study done in this journal was an examination of orthographic learning and self-teaching in a bilingual and biliterate context. The aim of the study was to figure out the advantages and/or disadvantages of a student learning a native language when they are either monolingual, bilingual, or biliterate, and the study was focused on learning English because this is the most commonly learned non-native language in the world.
Since then, Motor Companies have made numerous types of vehicles to fit your driving style the best including SUVs, trucks, compact cars, luxurious cars, and sedans etc. Even countries across the globe have have joined the competition such as Toyota, Nissan, and other european c...
The Collier Encyclopedia’s definition for probability is the concern for events that are not certain and the reasonableness of one expectation over another. These expectations are usually based on some facts about past events or what is known as statistics. Collier describes statistics to be the science of the classification and manipulation of data in order to draw inferences. Inferences here can be read to mean expectations, leading to the conclusion that the two go hand in hand in accomplishing what mankind has tried to accomplish since the beginning of time – predicting the future. It is the notion of science that this is the most accurate way to predict events yet to occur and this has lead to it being the most widely accepted “fortune telling'; tool in the world today.
• Lower Operating Costs The per-mile fuel cost of operating an electric vehicle can be less than
In fact, automobile owners don’t have the realization that their vehicles are money eating machines. For instance, Erin Stepp (2015), author of Annual Cost to own operate a Vehicle, states that, “the annual cost to own, and operate a vehicle has fallen to $8,698”. Certainty, automobile owners are curious to know as to why they pay a substantial amount to own an automobile?
There are many options that affect their car prices such as engine size, equipment levels and motor sport versions. This means you can purchase a base model (which is the cheapest) and then add options which may cost as much as ? 20,000 more per car. Examples of price: Model ----- Lowest Price.
