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.

8. Ideas for further investigation

7. Draw conclusions

5.Analyse and interpret

4.Present the data

3.Record data

2. Plan data collection

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.

  • Statistics: The Four Different Methods Of Descriptive Statistics

    In statistics, a population is a collection of individuals, things, events, etc. The population is the topic that one wants to make inferences on, whereas a sample is a subset of the population that is being collected—to be studied. After the sample is studied in statistics, one draws an inference of the population. There are four general sampling methods used in statistics: representative sample, random sample and quasi-random sample, stratified and quota sample, convenience sample, and purposive sample. A representative sample should be unbiased and thus properly indicate a characteristic of the entire population. In a random sample nothing is biased; in other words, every individual, thing or event in the population has the same chance of being selected for the sample. Therefore, because of the randomness of the sampling, the selection of one item from the population in no way effects the selection of another item. A quasi-random sample is simply a number (nth), which is

    As a population, we are bombarded with percentages and statistics, but how does one know if what we are being told is correct? The book How to Lie With Statistics by Darrel Huff was written to help readers better understand statistics especially when they are presented to us in ways that can be misleading or misunderstood. The book is not meant as a guide on how to change or manipulate statistical numbers. However, if statistics are not presented properly or perhaps purposely misleading people, this book will help readers question or form their own opinions from data. Most people simply are not that interested when you hear the word statistics and many times people do not believe the numbers presented. This mistrust occurs most often for two reasons: the person not being able to see the raw data and where or how it was collected and the person not being able to verify the credibility of the information presented. Throughout the book, Huff discusses different statistical techniques that can be used improperly and how one can discern good statistics from those that may have been manipulated.

    The clarity and applicability of the study findings rely heavily on a researcher’s ability to effectively identify, code and categorize themes and patterns unearthed in the data acquired. As a result, it is of the utmost importance to ensure that a researcher’s analytical skills be strong. Researchers must document and report all analytic processes wholly and honestly so that the findings can be evaluated for credibility or replicated in the future by other scholars. In order to analyze the vast amount of qualitative data generated from the interviews, grounded theory will be employed to analyze the textual data. According to Bhattacharjee (2012), grounded theory is “an inductive technique of interpreting recorded data about a social phenomenon to build

  • Probability Theory Statistics

    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.

All of these factors are impacted together for the automobile industry as a whole.
