A=1 and N= a positive integer. Y=X2 X Height Width Gradient 1 1 0.5 2 2 4 1 4 3 9 1.5 6 4 16 2 8 Looking at the results above I can see that the gradient is twice the X value, the height is X2 and the width is 1/2 the X value. This shows me that there are several patterns in the graph but there is not enough to make a formula on so I am going to do another graph Y=X3 X Height Width Gradient 1 1 0.33 3
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
The Change in Resistance of a Carbon Paper Introduction The aim of this experiment is to see how the resistance of a carbon-coated piece of paper changes when the different variables change. Variables A variable is a change in an experiment that could alter the outcome/results of that experiment, and for this experiment the main variables are type of paper, width of paper, length of paper, and temperature. We are going to be studying how changing the width of the paper affects
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 the
Investigating How the Size of a Shadow Depends on the Angle at Which the Light Hits the Object Introduction ============ The aim of the project is to see which factors affect the size of a shadow and then to look more closely at one of the factors to see how exactly it varies the size of a shadow. Variables that may affect the size of the shadow ================================================ Although, I will investigate how one factor affects the size of a shadow, there
The Relationship Between the Length of Constantan Wires in a Circuit and the Current Aim To investigate the relationship between the length of constantan wires in a circuit and the current flowing through. Introduction ============ In a conductor electrons are able to jump between atoms. However in insulators they remain around a single atom unable to move. Constantan, a metal, unlike most other metals is a poor conductor although it is also a poor insulator. Being a metal it
Factors Affecting the Resistance of a Metal Wire 1. Investigate some of the factors that affect the resistance of a metal wire. The current and voltage will be measured and then V = IR will be used to calculate the resistance. The potential divider circuit produced better results in the investigation into how resistance depends on the number of identical resistors connected in series, so this circuit will be used for this investigation, too. Variables and Constants 2. Possible
Stabbing is the most common cause of homicide in the United Kingdom. Stabbing can be caused by so many objects, for example steak knives, scissors, screwdrivers, broken glass bottles and so on. The individual characteristics of these instruments create specific features when they penetrate a surface of fabrics and skin. When examining textile damages, two common techniques are considered i.e. macroscopically (with the naked eye) and microscopically examining the area that might have possible damages
Concert Critique of Mozart and The Height of Classicism On Sunday, December 07, 2003, I attended the Mozart and The Height of Classicism concert that was held in the Lincoln Theater of the New World Symphony orchestral academy. Conducted by Nicholas McGegan featuring pianist Robert Levin. There were two pieces of music during this concert, one of the movements was performed by the pianist alone as a solo, Mr. Robert Levin. The program’s title was Wolfgang Amadeus Mozart, Chaconne from Idomeneo
The Relationship in Height and Weight of Students INTRODUCTION In this investigation, I intend to find out whether there is a relationship in height and weight in students, and how this relationship changes between girls and boys, with age. I have chosen to investigate the relationship between the height and the weight as I think that the height and the weight are the only two categories that will give a clear correlation. If I was to investigate the relationship of two other categories
Investigating How Length and Width of Copper Wire Affect the Current of a Circuit Task: To investigate how length and width of copper wire affect on the current of a circuit. Prediction: In this experiment, the input variable will be changing the length of the copper wire used in the experiment, and also the SWG of the wire, which means the width of the wire. By changing this variable, the current the circuit will vary. With my knowledge in science and some
Statistical Investigation Into Height and Weight of Students My hypotheses are as follows: ~ 1. Year 11 students are, on average, taller than year 9 students. 2. There is better correlation between height and weight in year 7 than there is in year 11. 3. The taller someone is the heavier they are. Below are the sampling methods that I have used in my coursework: Stratified Simple Random Stratified sampling can be defined as the process where the population is divided into
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
An Investigation into the Relationship Between the Resistance of a Wire and Its Diameter and Length Introduction In this investigation I hope to see whether there is a relationship between the thickness of a wire and its length with the resistance in which it produces. First of all, what is resistance? Resistance is calculated as R=V/I Where R is resistance, V = Potential Difference (Voltage) and I = Current (Amount of charge flowing per second) Resistance is the property of a conductor
Investigating the Effect of Temperature on the Height a Squash Ball Bounce Aim: To investigate the effect of temperature on the height a squash ball bounces. Prediction: I think that the higher the temperature of the squash ball, the higher the squash ball will bounce. I think that as the temperature doubles so will the height of the bounce. I think that they will be directly proportional. Scientific Knowledge: If you drop a ball onto a hard floor. It will rebound, but even the bounciest
The Effect of Height of a Ramp on the Speed of a Trolley For this piece of coursework, I intend to investigate the relationship between the heights of a ramp to the change in speed. I will be measuring the speed from these heights: - * 5cm * 10cm * 15cm * 20cm * 25cm. Formula AIM The aim of this investigation is to find out what the relationship his between the height or a ramp and the change in speed. Hypothesis The greater the height of the ramp the more the
Investigating the Relationship Between Height and Weight For my coursework I was given a reasonable amount of data based on ‘Mayfield High School’. Mayfield High School is a school for students aged 11 to 16. Hypothesis 1 For my first hypothesis I have decided to make an exploration on whether, ‘In general the taller you are the more you weigh’ I predict that the more a person weighs the taller they will be, meaning there will be a general pattern. But there will be some exceptions
could reduces their precision and influence on their accuracy. (Sicotte et al, 2010; WHO, 2000) 1.4 Aim of the study The aim of this study report was to interpret and appraise information related to nutritional status from measures including height, weight, waist circumference, ulna length and mid-upper-arm circumference (MUAC) assessed during a
me. Since the concept of inequality is existent, I decided to try to find where it was located in Jersey City. Jersey City is divided into several sections: Heights, Downtown, Journal Square, McGinley Square, Westside, Bergen/ Lafayette, and Greenville. The major races in these areas also differ greatly throughout. Starting with the Heights and Downtown, the white population is highest. Journal Square has many Indians while McGinley Square holds mostly Middle
Swimming Problem Maths Investigation Introduction ============ A group of swimmers are following a training schedule that requires them to dive into the water and swim one length of the swimming pool. They must keep doing this until they have completed 20 lengths. For safety's sake they have been allocated a single lane of the pool and all the swimmers must swim in the same direction in single file. Half of the swimmers say that it will be quickest always to swim in the same direction
