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
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
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
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
readers and be people that want a lighter read. It will be interesting to see how accurate my prediction is. I will be looking at: · Average Word Length · Average Sentence Length · Reading age There are many different newspapers; they range from tabloid papers to the broadsheet papers. The tabloids are a lighter read to the more involving descriptive broadsheet papers. Different newspapers are written to suit these preferences. In the tabloid papers the wording used is less profound
problems of data collection and about possible sources of bias and problems in random sampling. However, this method would have been very time-consuming and I may not have been able to collect enough data to demonstrate my ability at using a range of statistical techniques. Secondary Data -------------- When I was researching into possible sources of data, I was told that data that had been collected about students at a secondary school was available. When I looked at the data, I
Statistics Investigation Introduction I was given some data for 60 pupils in the school, with their height, foot length and gender. Firstly, I decided to compare this data by putting this data onto a graph and see if there is a correlation between height and foot length. I think that taller people will have bigger feet, which will be my hypotheses. Hypotheses My hypothesis is that taller people have bigger feet. Aim To find out if there is a correlation between height and
accurate representation of the average. iNZight’s ‘Visual Inferencing Tool’ will be what I use to display using the data. It will present this as a box and whisker graph. I will then analysis the data distribution discussing skews, inter-quartile range, range, shape etc. I will make a first judgement based on what I see being presented. From there I will create a difference between medians bootstrapping confidence interval, this is so I can produce reliable intervals that will potentially provide evidence
Investigating the Relationship Between the Length and Width of a Leaf Aim: To investigate if there is a relationship between the length and width of the leaves. I will also investigate summary measures to represent my data. Data Collection: I choose to collect my leaves from a tree in my back garden, as it was easy to access. I picked the leaves from different places and different heights around the tree so that my sample of leaves would be random. I choose
Statistics Hypotheses 1. The higher the IQ, the higher the average SATs results. There will be a stronger relationship between the girls’ IQ and SATs results than the boys’. 2. Boys will have a higher IQ than girls. 3. IQ will increase as age increases. Plan I have been given two sheets of containing 100 pieces of data on each. The data is secondary as I have not collected it myself. One set is from key stage three and the other from key stage four. The data includes year group
Investigating the Factors that Affect the Price of a Second Hand Car Introduction I am going to test which factors affect the price of a second hand car using a variety of different statistical techniques. From what I discover using these techniques I will conclude which factors are the most important. I will examine only cars within the reach of a normal family, i.e. not luxury cars. I will also exclude classic cars as these are unlikely to perform like normal second hand cars.
Missing Some Graphs Handling Data Coursework Introduction This is based on fictional data on a school called Mayfield high school. I will be comparing two variables I have chosen to compare the relationship between the height and weight of the pupils in the school. It will be involving the following year groups seven, eight and nine. The data that I have been given to me is a secondary source, which was provided to me by teacher which was from the internet. The data has provided me with each
did a stem and leaf diagram which shown me that most males were making few mistakes and the bulk were in the regions of 0-20 whereas I could see that only one females scored from 0-10 and a bulk scored from 10-30 which is a bit greater than the range of the males indicating that the females are making more mistakes than the males. From this hypothesis the evidence that has been shown clearly supports my it, but against it could be argued that on a Friday the traffic is greater because of
Introduction A series of sampling techniques were used in the field in order to estimate the amount of biomass that an area contained. The experiments were conducted at the Bisley Park on a Saturday. Two different methods were employed, namely quadrat-based methods and the disc-pasture metre method. The results gained from these samples were used to create an estimate of the biomass in the area. Materials and Methods There are two techniques used in the quadrat-based methods, namely the
of the noted species. The appearance of Hydnum repandum is quite unique. The stipe of the fungi can range from two to seven centimeters tall, and one to three centimeters thick (Wood). The surface of the stipe can range from cream to yellow in color, and is dry and smooth. The cap of the mushroom is two to ten centimeters broad, with a smooth, dry surface (Graham 84). The caps color can range from cream to orange. It has a thick flesh that is very brittle, with a mild taste and odor. The hymenophore

The Power of Meditation The correct definition of meditation is to think constantly of something. You become that on which you meditate. Think of God, you become God. Think of stone, you become a stone. The only thing that the process of meditation is really meant to teach us is to remind us that there is something above from which we have come here and it is our first duty to get back where we belong. Meditation is not only meant for the saints it is meant for everyone. Another point to emphasize
concentrate on the differences between the denominators rather than the ‘fractions’. So I am looking for a formula that will explain the sequence: 2, 6, 12, 20, 30. First of all though I decided to extend the sequence in order to have a broader range to work with. I used a calculator to work out the following denominators finding the difference between [IMAGE] and [IMAGE], [IMAGE] and [IMAGE] all the way up to [IMAGE] I set the differences out in a table to try to find the pattern: nth
