High School”. body mass index = weight/height² Phase A: As 1180 pupils is an extremely large number to work with, I have decided that I will carry out a sample. The type of sample that I will carry out is called a stratified sample. This means that I will arrange them all in the order that I am going to investigate, and then keep deleting entries and save every nth term. I have done this so I get a nice small sample which is easy to work with, and most importantly, represents the data

Investigating the Relationship Between Foot Size and Height I predict that the taller the pupil is, the bigger their foot size will be. Plan ==== I’ve been given 60 pieces of data from pupils, about their height and foot size. I will be using a piece of software called Fathom where I will place this information into a scatter graph, to see whether or not my hypothesis is correct. Fathom will produce a line of best fit on my graph and tell me what my r-value is. The r-value shows

think this is because as you grow taller there is more build up of your body and therefore more of you resulting in an increase in weight. Plan STEP 1 · Investigate the data as a whole and take out any anomalies STEP 2 · Calculate the Mean and Standard Deviation of the height and weight of the whole School STEP 3 · The 1183 pieces of data is too large to deal with so I will reduce the data because it is easier to use mathematically. I will take a random sample of a 100 students

Analysis of Data Between Height and Weight in Girls and Boys In my first investigation, I will be analysing data between height and weight in girls and boys. I will also use this data to compare the results between boys and girls as well. I will use a variety of graphs to show this. PREDICTIONS I predict that as the heights increase, so will

Data Handling Project Aim I aim to investigate in the following project whether the mileage of a motorbike will affect the percentage depreciation of the motorbike, and eventually using the information I have, find out which model of bike will be the cheapest for a certain amount of miles that the user will expect to travel. E.g. if a cyclist is expecting to use his bike until it had travelled X number of miles which make of motorbike would be he cheapest. The information below is

The Relationship Between Height and Weight for the Pupils in a Secondary School Introduction ============ For this investigation, I am going to use data on secondary school pupils to find the distribution of the data and also to look for any meaningful relationships between the heights and weights of the students. When I was looking at the various things that I could study, one of the factors that I looked at was data collection. The amount of data was large, spanning across

Statistics Coursework Introduction ============ The data that we are going to use is secondary data that has been collected from a high school. It is made up of a collection of qualitative and quantitative variables . This also includes both discrete and continuous data. The data is in the form of a spreadsheet, making it easy to identify the required information for the investigation. I am using this secondary data as it would be easier than collecting primary data myself. This

Comparison of Newspapers Introduction ============ 'The Times' newspaper is universally accepted as Britain's national newspaper. I have been asked to investigate the concerns of the editor that the sales are lower in comparison with the tabloids. I am going to investigate the lengths of the words, how many words there are in a sentence and the reading age if those who read the newspapers. Hypothesis 1 ============ I hypothesise that the world length for the broadsheet newspapers

big but the foot size is not. I can see this because the points are far away from the line of best fit. The graph shows a positive correlation, which means there is a positive gradient. As the value of the y-axis increases, so does the value of the x-axis, which means that in general, as the height increases, so does the foot size. This means when I square root the value of r2, to get r, I know to take the positive square root of 0.69. For the above graph, r=0.83 to 2sf. For graphs showing

A Comparison of Broadsheet Newspapers with Tabloid Newspapers Investigation 1 Hypothesis 1 "Broadsheet newspapers have a longer average word length than tabloid newspapers" My theory is that broadsheet newspapers use a more complex style of language. In effect I think this will result in a longer average word length in a broadsheet than in a tabloid newspaper. Both newspapers will have a large amount of short word included in the articles, however, this can not be avoided due

Data Handling In this coursework, I shall investigate whether there is a correlation between the height and weight of students at fictional school, Mayfield High. I expect there to be a positive correlation between the height and the weight of the students as it would make sense if the taller someone was, the heavier they would be. I am going to investigate the differences between each year, and between male and female overall. I am doing this for a number of reasons. Firstly, the range

Formulation Of A Theory The certain factors that influence the accuracy of estimation is mainly: Age, the time of day it is processed, gender and the style of the survey. The reason age has an affect on the accuracy of estimation, is because if the person is too young or too old the survey may not be reliable enough in order for it to be processed into a data collection sheet the reason being that they may not be suited to the imperial or metric measurement used in modern days. The young

Comparing Left-Handed and Right-Handed People Are left-handed people more intelligent and creative than the right-handed in Mayfield High School? In my coursework, I am going to focus on the IQ, Key Stage 2 results, favourite colour, favourite subject and height of students in Mayfield High School. Specify, I will concentrate on the Year 7,8 and 9 boys and girls because these year groups have closer relationship with the Key Stage 2 results. In the following coursework I am going

Newspaper Comparisons Introduction For this statistical coursework I will compare the length of words in tabloid and broadsheet newspapers. My sources are 'The Sun' (a tabloid) and 'The Times' (a broadsheet). Predictions / Hypotheses * Broadsheets, on average, use long words, while tabloid newspapers generally contain shorter words than broadsheets. * Tabloids have a wider variation in the number of letters per word than broadsheets * The most common (modal) number of

Relationship between Height and Weight I am using the data from Mayfield high school as I am unable to use data from Nabwood School. This is because although the school has a database system, information regarding height and weight of year 10 and 11 students will not be accurate as it was taken when students came to the school in year 7, which was three or four years ago (if they are now in years 10 and 11). Therefore to try and update the database with the latest height and weight of year

Data Handling Project In this piece of coursework I am investigating how the weight of a sample of pupils can be affected by various factors e.g. age, gender, height etc. I have chosen to compare the weights with the three factors listed above: age, gender and height and throughout this investigation I am aiming to show that weight of a certain group of people may be affected by certain factors and that other factors may have no affect on the weight at all. Plan: I have been given

A Comparison of Newspaper Articles Introduction I have chosen the "Read All About It" option for my Maths Coursework. This involves comparing articles from newspapers and comparing them. I have chosen to use two newspapers for my investigation. I have chosen to compare articles from a Tabloid and a Broadsheet newspapers. The papers I have chosen are "The Mirror" and "The Guardian". I am predicting that the articles in the broadsheet newspapers would be more complex and often longer

The Relationship between Height and Weight in Mayfield High School The hypotheses that I have made are effective but simple. I expect to find that: 1) Boys weigh more than girls 2) Girls are taller than boys in KS3 3) When I investigate the relationship between height and weight, I expect to find that the taller you are, the heavier you weigh. 4) Gender may affect the results that I will have attained by the end of my investigation. I possess a secondary source of data that

rule but fail to satisfy the empirical rule. Essentially, the researcher can be 98% confident that the average upper leg length is between 37.47cm and 40.25cm for females, and between 41.50cm and 43.64cm for males. At the 90% level of confidence, the means would lie between 37.88cm and 39.85cm for females, and 41.71cm and 43.44cm for males. References Black, K. (2009).

this as my Ho: µ=71 inches because I am 5’11’’ and I feel short in most places at this university. So I hypothesized that the Ha: µ≠71 inches and tested my data versus the average I was given. I found the mean (X ¯ ) to be 70.7165 inches which was not that much lower than the Georgia male height mean. The standard deviation for the sample came up as ...
