Mayfield High School

Introduction I have chosen to compare the relationship between IQ and Key Stage 2 Results and my hypothesis is that the greater the person's IQ, the better their Key Stage 2 will be. I will use scatter graphs to represent my data and to find out if my hypothesis is true. For the scatter graphs I will be drawing the lines of best fit, finding the equations of these lines and using this to compare. I will also be using cumulative frequencies and box and whisker diagrams to look at the interquartile range and the median. If my hypothesis is true, I expect to see a positive correlation. Sampling the Database For my whole database I will use stratified samples, where the samples reflect the proportions of the whole population. Therefore, the school is growing and there are more students in year 7 than year 11. This means, there are likely to be more year 7 students in the sample than year 11 students. To ensure that students from different age groups are equally represented my need to take this type of my sample. In a stratified sample my sample values from a particular group in proportion to that group's size within the whole population. An example of a stratified sample in connection to Mayfield High School is shown below. For example, I want to make a population of 60 from the population of 1183 shown below from Mayfield High School. Year Group Number Of Boys Number

Mayfield High School Data Handling Project

Mayfield High School Data Handling Project Aim: I am going to collect and express evidence to support (or not support) the hypothesis that: Males have a higher IQ than females, in years 7-9 Collecting the data For my project I needed to collect data on a number of students IQ, gender and year. I obtained all of my information from the Mayfield High School database. This is a fictitious school but the data is based on a real school. Because it is based on a real school, the evidence will be reliable and will be accurate enough for me to draw conclusions. The database held information on a total of 1183 students, this will be very hard to analyse because there is a lot of data and drawing graphs and diagrams could be tricky. I have decided to take a sample of the students in years 7,8 and 9. I put the list of students on the computer in order of their year. I then picked out one from every 10 students, this gave me 10% from each year. The amount I picked from each year is proportional to the size of the year. This is called stratifed sampling. My sample is shown below: Age Gender IQ 7 Female 00 7 Female 02 7 Female 02 7 Female 04 7 Female 96 7 Female 90 7 Female 01 7 Female 22 7 Female 07 7 Female 89 7 Female 11 7 Female 02 7 Female 08 8 Female 06 8 Female 06 8 Female 94 8 Female 11 8 Female 10 8 Female

Mayfield High School - GCSE Maths Coursework

Mayfield High School - GCSE Maths Coursework Hypothesis: I believe that taller students will be heavier than shorter students. I also believe that males will be taller than females. I am investigating these topics because it is a common idea that this is true, and I am interested in proving or disproving them. Plan: To test my hypothesis I need to sample a certain number of school students. I intend to sample the school population of Mayfield High School, taking a percentage of the 1183 students. I am only taking a percentage of those 1183 to keep the data to a manageable extent. To sample this data, I will use a stratified sampling method, and then calculate different averages of the data, for example mode, median, range, to help demonstrate the typical student. I can also put the data into Box Plots and Scatter Diagrams. This will help to obtain the accuracy of my data, and help me form a strong conclusion to relate to my Hypothesis, and find out if my data correlates well or not. I will find these averages, as they are quick to do and will help me to find out what the typical student is like. Eventually, I will put the data into stem and leaf diagrams - this will aid me to find the mode, median, and range values in an easy way, and also so I will be able to understand it more clearly. Another aim is to draw a scatter diagram because it is a good way of comparing two

Mayfield High Statistics Coursework

Mayfield High Statistics Coursework Introduction I am going to complete a statistical investigation around the fictitious data of Mayfield high school, which has data that would represent a real school. I will be using various techniques that I have recently learnt, studied and captured to produce a successful & efficient piece of coursework. Mayfield high is a fictitious school that consists of 1183 male and female students in years 7 to 11. The data given to me on these students comprises of height, weight, eye colour, favourite TV program, hair colour, eye colour, gender and favourite type of music etc. Data Data is made up of a collection of variables. Each variable can be described, numbered and measured. * Data that can only be described in words is qualitative. Such data is organised into categories, such as make of car, colour of hair, etc . * Data which is given numerical values, such as shoe size or height, is quantitative. This type of data can be sorted into two categories: - Discrete data can only take certain values, usually whole number, but may include fractions (e.g. shoe sizes). - Continuous data can take any value within a range and is measurable (e.g. height,

Mayfield Maths Coursework

Maths Coursework My Hypothesis The hypotheses that I will investigate are: : The higher the IQ results the higher the Key Stage 2 results. I think that this is true because both the IQ and the key stage 2 levels are meant to be indicators of intelligence. If this is true then the two should have a fairly large degree of correlation 2: Girls are more intelligent than boys. I want to test this as many reports over the last few years have said that girls are much more intelligent than boys, I want to see if this is true with the sample that I have chosen. Introduction I am going to investigate the relationship between the IQ and the Key Stage 2 results for English, Maths and Science. I will compare the IQ results with the Key Stage results to find out if there is a correlation. I will then use a sample to test the hypothesis that girls are cleverer than boys. I will find this using information about a school called Mayfield Data High School, which was provided by the exam board. The spreadsheet provided by the exam board contains 1183 sets of data. This would be too many to investigate and so, for my research so I will use 10% of the data (approximately 120), which should be large enough to give me accurate results. For my investigation I will only need to use the following information to help me with my task: o The IQ o KS2 results for English, Maths and Science

statistics coursework

Handling data- Statistics coursework In this coursework, I will be comparing weight of the pupils with the amount of hours of T.V they watch a week and I will observe the correlation between these two factors. I hypothesis that the amount of T.V watched per week will affect weight. I hypothesis that the more TV watched per week, the higher weights. I chose this line of enquiry since I think that there may be a correlation between the two, as people who watch lots of TV will be less active and do less exercise and so will weigh more. I will be investigating to see whether this is true or not. As well as my original hypothesis I will also enquire into the difference between genders, I will investigate wherever boys or girls weigh more and wherever boys or girls watch more TV. I initially believe that boys weigh more then girls, as from my own knowledge I believe they are normally bigger and taller which should cause higher weights. I will find out wherever this is true or not. The following table is data based on the boys and girls who attend Mayfield High school. Year group Boys Girls Total 7 51 31 282 8 45 25 270 9 18 43 261 0 06 94 200 1 84 86 70 Stratified sampling A stratified sample is a sample in which you have a proportional amount from each year so that it is a fair sample. From my data, I need to take a proportional amount from each year,

Edexcel GCSE Statistics - Coursework Aim * My aim in this coursework is to investigate a possible relationship between the heights, weights and gender of a number of runners who are members of a club. Hypothesis * My main hypothesis is that generally, the taller someone is the more they are going to weigh. Sub-Hypotheses * I believe that for females, there will be a stronger correlation between height and weight. * I also believe that on average, males are going to weigh more and be taller than females. Plan * I am going to collect data about the club members from the Edexcel website. Despite the fact that this is secondary data, I believe Edexcel (a recognised examination board) to be a trustworthy source. * I am going to take a random sample of the club members, stratified on gender. This will provide me with a sample representative of the population. I am going to take data from 100/277 of the population, as I believe that this will provide enough data to support my hypotheses. I am also going to take the sample using the random number generator button on a calculator, as this will help to eliminate bias at this stage. * As I only require the heights, weights, and gender of the club members, I am going to sort the data using Edexcel so that only the necessary fields are shown. Any anomalous results in the data will be replaced by a new result, to help ensure

Statistics Coursework

Statistics Coursework Aim: We have been given data about the different aspects of life of students from Mayfield High School. The data includes information such as the height and weights of the students, and educational stats such as KS2 results. My aim is to investigate the relationship between two or more of these pieces of information. Hypothesis: My main hypothesis is that: "As IQ increases, the total KS2result also increases". I chose this as my main hypothesis because I think that as IQ is natural intelligence, having a higher IQ would mean that a student could easily obtain higher KS2 results. Related Hypotheses: I have chosen to investigate two related hypothesis, these being: 1. "Year 7's have higher total KS2 results than Year11's" 2. "Girls obtain higher percentage of results of a 4 or above in each KS2 test than boys" I have chosen these as my related hypotheses as they allow me to look more closely at my main hypothesis. I have chosen the first one specifically because I have heard that exams were getting easier, and I wanted to investigate this to see what I heard was correct. I have chosen the second one because I believe it to be true; in general boys spend a greater amount of time outdoors and so less time studying than girls do. Preliminary Studies: I have carried out a small scale preliminary study for my main hypothesis, to check if there

Squash Ball Investigation

Squash Ball Investigation Introduction A squash ball is a ball made out of rubber, which is hollow inside. There are wide ranges of squash balls you can get, they affect the bounce of the ball, and you can tell if a squash ball is different by feeling how soft or hard it is. I am going to investigate the affect of squash balls dropped at different heights have on a squash ball I.E.: If the squash ball is dropped at a low height will it not bounce as good as it will bounce when dropped from a high height. The variable I will change is the height of each squash ball dropped and I will investigate if a squash ball bounces better when it has dropped from a high height or a low height. Prediction I predict that when the squashed ball is dropped from a high height it will bounce better than when it has been dropped from a low height. This is because when it is further away from the ground it has more potential energy to bounce back up again, and when a squash ball is dropped at a low height then it has less potential energy to bounce back up again. The equipment I will use. Fair test To make the experiment a fair test I will drop each squash ball 3 times and then I will calculate the average of my results and plot the average on my graph, the only variable I will change is the height of the squash ball dropped. To make this a fair test I must also keep the squash balls

Telepathy Investigation.

AS Maths Statistics Coursework: Telepathy Susan Barnes Telepathy Investigation Background "Telepathy is an exchange of information between two people without any known sensory or energetic interaction." People who are telepathic are able to communicate what they are thinking by thought process only. The aim of this assignment is to assess whether people attending New College possess telepathic powers. I also aim to investigate the factors that affect telepathic activity, such as whether they are Believers or Non-believers in telepathy. The Duke experiments were carried out on telepathy, clairvoyance and precognition used specially designed cards called Zener cards. About the size of regular playing cards, these cards were composed of decks of 25 cards, with each card having one of five symbols on one size: a cross, star, wavy lines, circle and square, similar to those cards being used for this investigation. Aim and Strategy The aim of this investigation is to analyse the results of a telepathy test to determine whether any of the people in the sample questioned are telepathic. These results from the sample can then be used to represent the chance of telepathy occurring in similar people. This means that similar people will be questioned, by opportunity sampling. For example, instead of asking random people, I have chosen to ask only males and females between 16
