To what extent will does correlation and extrapolation assist Nintendo in forecasting sales? (34 marks) Correlation is the relationship between two variables. Extrapolation is related to correlation, as it involves plotting a linear regression curve (also known as a line of best fit) which is based upon how two variables are correlated, and extending the line to predict future values. For Nintendo, a computer game and console manufacturing company, a common example would be the relationship between the level of advertising expenditure and the effect of this on sales of its products. The graph to the left shows a strong positive correlation between sales and advertising, meaning if Nintendo increases its advertising, they can expect to see an increase in sales. Because all values are close to the line, as advertising expenditure increases on the x-axis, sales on the y-axis increase proportionately. The regression line can be extended past the '80' figure (meaning £80million) to predict what sales will be like if they spend £100million or even £900million. The uses of such analysis to Nintendo are to an extent very valuable. By creating a scatter graph like the one above, Nintendo can spot trends and forecast future events. For example, they could estimate demand at a certain point in the coming year. One would expect demand to surge at Christmas time when people are
Jose Cree Explore the presentation of revenge in 'Hamlet' Revenge is a key theme in Hamlet. It is not only essential to understanding Hamlet's character, it forms the structure for the whole play, supporting and overlapping other important themes that arise. Though it is Hamlets revenge that forms the basis for the story, tied into this is the vengeance of Laertes and Fortinbras, whose situations in many ways mirror Hamlets' own. By juxtaposing these avengers, Shakespeare draws attention to their different approaches to the problem of revenge and how they resolve these. The idea of revenge is first introduced by the appearance of the ghost in act 1 Scene 5, and linked to this is the theme of hell and the afterlife. At the end of this scene, Hamlet is irreversibly bound to revenge for the duration of the play, 'speak, I am bound to hear' 'So art thou to revenge'. The ghost appears with the sole aim of using his son to obtain revenge on his brother, and so every word he speaks is designed to enrage Hamlet and stir in him a desire for vengeance. He uses very emotive language to exaggerate the enormity of the crime, and he concentrates Hamlet's attention on the treachery of Claudius. His description of the murder itself demonises Claudius and contains many references to original sin, 'the serpent that did sting thy fathers life now wears his crown.' Hamlet, who has been
. Plan Aim To investigate how the length of a simple pendulum affects the time for a complete swing. Variables length The length of the pendulum has a large effect on the time for a complete swing. As the pendulum gets longer the time increases. size of swing Surprisingly, the size of the swing does not have much effect on the time per swing. mass The mass of the pendulum also does not affect the time. air resistance With a small pendulum bob there is very little air resistance. This can easily be seen because it takes a long time for the pendulum to stop swinging, so only a small amount of energy is lost on each swing. A large and light pendulum bob would be affected by a significant amount of air resistance. This might change the way the pendulum moves. gravity The pendulum is moved by the force of gravity pulling on it. On the Moon, where the pull of gravity is less, I would expect the time for each swing to be longer. Theory When the pendulum is at the top of its swing it is momentarily stationary. It has zero kinetic energy and maximum gravitational potential energy. As the pendulum falls the potential energy is transferred to kinetic energy. The speed increases as the pendulum falls and reaches a maximum at the bottom of the swing. Here the speed and kinetic energy are a maximum, and the potential energy is a minimum. As the pendulum rises the

They emulate scenarios that children can identify with, more specifically the relationships between the students and their teachers/head teachers. As a result the language used
Explain why the depression of 1929 was a 'godsend' for the Nazi Party Of all European countries, none was hit harder than Germany by the stock market crash of October 1929. Germany, who was still suffering from the Treaty of Versailles, had borrowed very large sums from American banks, with much of the money repayable either on demand or at short notice. These loans were of course recalled, and bankruptcies in Germany rose sharply from the start of 1930. Unemployment rose sharply, too. The German economy plummeted with the stock market and the situation Germany found itself in resulted in even more faith being lost in the Weimar constitution. This situation was a godsend for the Nazi Party as it enabled them to gain public support. Having lost faith in what they already felt was an indecisive Government, and after the 'stab in the back' myth having been circulated throughout the country, Germany became increasingly hard to govern. Hitler, an inspiring and energetic speaker, took this opportunity to present himself and the Nazi party to the German people. Showing himself as a strong leader, he promised to abolish the Treaty of Versailles and restore Germany to power. This was one of the ways in which the Great Depression aided the Nazis. Because of the people of Germany falling into poverty and despair and being eager for help, Hitler's talk of a new Germany and his
Say 'NO' to Plastic Bags! Gone are the days when our grandmothers used cloth bags and straw baskets to carry the grocery while going around in the market. For small items there were brown or newspaper bags, but now whether you buy clothes, groceries, meat, books or buttons, the shopkeepers only use plastic bags for the items. Have you ever wondered the beneficial and dangerous side of using plastics? I have and I have found that plastics are very harmful to the environment, even though they are very useful to carry things around. You must be wondering how just a plastic bag, can be so detrimental to the environment. Allow me to tell you how. Plastic bags are cheap and are light in weight. They are also water and chemical resistant and require less energy in manufacture.1 These are the advantages of using plastic bags, but above all these benefits they are still very harmful to the environment! Let's begin with a story to give you all an idea what actually happens when you just throw away a plastic bag, without considering what harm it can cause. A young boy asks a shopkeeper for a plastic bag for the items he had bought; not knowing that it would harm the earth for not carrying the items in his hands or pockets. As soon as he arrives at his doorstep, he throws away the "plastic bag" now regarding it as a useless piece of junk. The winds carry the bag into the river and

Scene V, Blanche: "Come in"-"Ahhh Merciii" Discuss this extract in relation to the rest of the text paying attention to structure, form and use of language. The ending section of scene five of Tennessee Williams's play 'A Streetcar Named Desire' has provoked much confusion and debate as to the writer's motives in regards to the portrayal of Blanche. One school of thought on the matter is that, in spite of the fact that Williams largely based the character of Blanche upon himself his primary aim in the play is to punish her for her failure to show empathy towards her homosexual husband Allan. Williams was of course a homosexual himself, living in a largely homophobic world where gayness was not a talked about subject. He often brought the issue up in his other works such as 'Cat on a Hot Tin Roof' where the characters Brick and Skipper and both portrayed as possible homosexuals. Blanches lack of empathy and compassion are highlighted once again in this extract when she totally fails to take into account the feelings of a second young man, and instead uses him to live out her fantasies of desire for her late husband. During the exchange between Blanche and the young man she is portrayed as seductive and dominant "I want to kiss you" making it clear that she is the one initiating the situation, this is a dramatic contrast to her normal persona around other men such as Mitch
Assess the Usefulness of Official Crime Statistics to a Sociological Understanding of Crime The Government publishes official statistics on crime in Britain annually. The main source of these statistics are gathered from recorded crimes by the police and courts and through the British Crime Survey (BSC) which is a large-scale victim survey conducted annually by the Home Office. The combination of both of these statistics should provide a picture of the full extent of crime in Britain, however, sociologists believe there are a number of factors that influence these figures and that these official statistics do not reflect a true representation of crime in Britain today. We shall explore these factors and perspectives further to assess whether the official statistics do serve a purpose in the reporting of crime in Britain. From the functionalist perspective Emile Durkheim stated that deviance is a necessary part of all societies and that police and the courts are necessary to keep deviance in check and to protect social order. Durkheim argued that crime is an inevitable part of society and that all social change begins with some form of deviance and in order for change to occur, and that yesterday's deviance must become today's normality. That a limited amount of crime is necessary and beneficial to society and that society could not exist without some form of deviance and it
How does changing the Concentration of Hydrochloric Acid Affect the Rate of Reaction between Hydrochloric Acid and Magnesium? Dependent Variable Volume of Hydrogen Produced - the volume of hydrogen produced in cm3 will be affected by the independent variable which in this case is the concentration of the hydrochloric acid. There is no way in which the volume of hydrogen produced can be controlled however make sure none is lost by making sure that the gas syringe is correctly connected. Measurements will be taken every 30 seconds for the volume of hydrogen produced for 5 minutes. Independent Variable Concentration - the variable which will be controlled is the concentration of the hydrochloric acid. The concentrations which will be used are 2M, 1.8M, 1.6M, 1.4M, 1.2M, 1.0M, 0.8M, 0.6M, 0.4M and 0.2M. The concentrations will be changed by using different measurements of hydrochloric acid and water. Controlled Variable The equation for the reaction can be seen below; Mg(s) + 2HCl(aq) --> MgCl2(aq) + H2(g) I will be controlling many of the variable which affect the volume of hydrogen which is produced. Temperature - The temperature will be controlled because if the temperature was to be changed this could affect the dependent variable. To control this the experiment shall be done in the same lab with no heating and no cooling will be done while the temperature will also
Efectos: La pobreza causa diversos efectos en la sociedad, tanto a individuales como a la sociedad en grupo. La razon de esto es que cada accion de un individual afecta a otro y a otro, es como una cadena de efectos lo cual concluye en un problema de sociedad. No importa si alguien goza de una vida lujosa, ya que la pobreza siempre afectara a todos los seres de la poblacion ya sean ricos o pobres por igual. Efectos de la pobreza en individuales: Devido a la pobreza hay diversos efectos que danan la vida de los individuales, estos efectos son a largo plaso, ya que es muy dificil salir de la pobreza aunque hay gente que se ha logrado superar pero esta es la racion minima de la sociedad. Ya que las posibilidades de superacion son minimas en este pais. Ejemplos de estos efectos son: - La prostitucion. Esto pasa ya que las mujeres no encuentran major trabajo que usar su cuerpo, ya sea para alimentarse ella misma o alimentar a miembros de su familia. A la ves hay veses que la misma pobreza las pone en un mundo de maltratos donde hay personas que abusan de la situacion en las que ellas se encuentran y lo que hacen es insitarlas a la fuerza a que trabajen como prostitutes fuera de su voluntad. - Robo: debido a la falta de comida, y de otras nesesidades primarias, las personas roban y se convierten en delincuentes. A la misma ves pueden haber muchas causas diferentes que llevan a
