Statistical Investigation
For my Maths GCSE's I am required to do two pieces of coursework one
of which is a piece on statistics.
The purpose of this project is to help me investigate a real life
situation using statistics. In this case I have been given some
quantitative data on the end of year maths test scores of children in
year 8. What I am supposed to do is compare the data by making
hypotheses to indicate if there is something comparable between the
results.
First I have decided it would be best to make my hypotheses. Also
since there is not a lot of data I have decided it would be best to
make only two hypothesises.
1. All the Boys total scores were much higher than the Girls total
scores.
2. People who attained good marks on Paper 1 attained good marks on
Paper 2.
Data Collection
The data of the test scores was given to me in excel format. On it
were the test results of paper 1, paper 2, mental and the total
scores. This same data was given for boys and Girls. There are results
for 59 Girls and 77 Boys. So then to make comparing the results easier
I chose a sample of 30 boys and girls. I chose this sample at random
so that my data would not be biased. I chose it at random by using the
sort then RAND on excel.

1.There will be two groups, the control and experimental groups. Each group will have the same amount of participants with equal numbers of boys and girls. The first group will be the control group(rest). The second group will be the experimental group(exercise).
...er what career field you may enter. The data has to be collected properly without it being so time consuming ,and it’s not only the functions that was collected in chapter 9 but the concepts that the entire Microsoft excel workbook is teaching can impact ones career effectively in a positive way. Excel creates a way for individuals to be on top information that is highly needed, without excel calculating this data will then become time consuming and then inaccurate, be smart about it and know what is what when dealing with different types data that’s needed depending on your career. It doesn’t if you’re a teacher, doctor, contractor, musician, or any other profession out there. Collect data the smart way. Be your own boss, and know what it takes.
Overall I believe that I got all the data I needed, and I felt that
A sample of children ranging from 4 to 13 years old are going to be asked to watch a Rainbow Brite video. The children will be randomly picked from a childcare center. To ensure that the children are going to be randomly assigned, the children will range in different age groups. The first group will consist of 4, 6, and 8 year olds. The second group will consist of 10,12, and 14 year olds. It would have to be a field experiment because you have to go out and collect the data.
In the first stage of this experiment there are two groups of boys that all have a similar family structure. Each team consisted of 11 members, who are introduced to each other and are taken to a boy scout camp
This paper is a critique of an article written by McKinney and Jones (1993) entitled: “Effects of a Children’s Book and a Traditional Textbook on Fifth-grade Students’ Achievement and Attitudes toward Social Studies”. In their research the authors examined the effects of a children’s book and a traditional social studies textbook on knowledge acquisition and attitudes toward social studies and the textbook in a sample of 57 fifth-graders. It is the intention of the present paper to develop analytical discussion and the holistic interpretation of the McKinney and Jones’s quantitative study (1993).

The study consisted of a significant number of females compared to males, which makes it invalid to conclude that the findings support the general population. A strength was that participants were selected at random. By doing so, the study remained unbiased, thus making the results more credible.
Scenario: While working as a police officer, you respond to a robbery in progress involving two armed suspects at a liquor store. Upon arrival, you and your partner interview three witnesses to the crime. While conducting your investigation, another unit informs you they have a possible suspect detained several blocks from the incident.
I have put my results in a table so that they will be easier to
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.
Often uses random sampling to select a large statistically representative sample from which generalizations can be drawn.

The simple random sampling is one of the types of sampling. The choosing element units are depends on the population with the identical chances being selected. The simple random are preferred from the size of N element population. The choosing m...
