To what extent will does correlation and extrapolation assist Nintendo in forecasting sales?
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

Biology Coursework To determine if the distribution of flora across Ellerbeck is due to chance. The valley containing Eller beck possesses a huge variety of different species of plant life, particular species are often found in specific places across the valley, to find out why these particular plants grow in the particular places I mean to investigate where different species of plants are located and what the conditions in those particular places are, investigating the effects of several factors on the distribution of these different species across a specific area of the valley. I believe that the varied distribution of the different species investigated is directly related to, and can be explained by the differences in the factors I will be measuring, that certain plants will grow in certain places in the area because they are more suitably adapted, in whatever way to the conditions in that specific place. This is a rough diagram of Ellerbeck. I plan to perform my investigation using two information gathering techniques, after first establishing a straight line across the valley by taking a bearing using a compass from one point at the top of the South side of the valley and following that bearing down the valley, across the beck and up the other side whilst performing both a line transect and an interrupted belt transect. I also plan to perform an interrupted belt

Compare and contrast the Functionalist and Marxist views of society.
Compare and contrast the Functionalist and Marxist views of society. Sociology has been classified as the last in a long line of emerging scientific disciplines which people have developed and explored in order to make sense of their world. Early theories such as the positivist approach of Comte, the functionalist views of Emile Durkheim and the conflict perspectives of Karl Marx have offered a view of why human beings behave as they do and how they fit together in society. Each theory has to some extent been shaped or influenced by the approach of others and many sociological explanations have comparisons or contrast that can be made. Browne once said "sociological perspectives centre on how much freedom or control the individual had to influence society" He goes on to comment on the two main approaches "structuralism is concerned with the overall structure of society and the way social institutions act as a constraint, or limit and control individual behaviour". Structuralism offers a view of the individual being controlled by the society they live in, Marx and Durkheim are similar in that they can both be described as structuralists, however their individual ideas are somewhat different. Functionalism was developed by Emile Durkheim, he believed like Comte that sociology should be viewed as a precise science and that society should be studied objectively. Durkheim
Investigate the water potential of celeriac.
Aim Investigate the water potential of celeriac. Apparatus Celeriac - this is the specimen that we will be finding the water potential of. .00 mol dm-3 sucrose solution - this will be placed in the test tube in which the experiment will take place. We will dilute the solution to produce a range of concentrations. 0.0ml Graduated Pipettes (x2) - I had a choice of 5.0ml, 10.0ml and 20.0ml graduated pipettes. I chose this size pipette because it is time efficient and accurate at the same time. It is an accurate piece of equipment because as opposed to standard pipettes, this graduated pipette has 0.1ml graduations to ensure the utmost accuracy. One pipette will be used for water and one will be used for sucrose solution. 250ml Beakers (x2) - these will be used to hold water and the 1.00 mol dm-3 sucrose solution in a safe environment. Cork Borer - this will be used to cut the precise shape of the celeriac. This will also ensure that the surface area to volume ratio is constant throughout the experiment. Razor - this will be used to cut the pieces of celeriac to a precise length. Ruler - this will be used to measure the length of celeriac that will be used in the experiment. Scales - they will be used to measure the mass of celeriac before and after the experiment with accuracy. Therefore, the mass increase/decrease can be calculated after the experiment. These scales
Preparation of propanone from propan-2-ol
Date: 11/10/2011 Exp. No.: 23 Title: Preparation of propanone from propan-2-ol Aim: The aim of this experiment is to prepare propanone by oxidizing propan-2-ol with acidified potassium dichromate solution. Introduction: Ketones and aldehydes are important series in preparation of other compounds and they are commonly prepared by oxidizing alcohol which is done in this experiment. The experiment is an oxidation reaction where a secondary alcohol (propan-2-ol) is oxidized by acidified potassium dichromate. The reaction does not need to be heated but should be placed in an iced water bath as the reaction is highly exothermic. The product is propanone and no catalyst is needed for the reaction. The propanone is serparated from the reaction mixture by simple distillation and is purified using anhydrous cacium chloride. The equation of this reaction is as follow: Chromic acid is produced in situ by adding potassium dichromate (VI) with sulphuric acid and water. K2Cr2O7 + H2O + 2H2SO4 ? 2 H2CrO4 + 2 NaHSO4 The term chromic acid is usually used for a mixture made by adding concentrated sulfuric acid to a dichromate, which may contain a variety of compounds, including solid chromium trioxide. Chromic acid features chromium in an oxidation state of +6. It is a strong and corrosive oxidising agent. Apparatus and chemicals: Apparatus: Quick-fit distillation setup,
The comparison of antibacterial properties of herbal products and standard antibiotics
The comparison of antibacterial properties of herbal products and standard antibiotics Introduction: This is As biology coursework, studying the area of microbiology the main investigation contains the comparison of antibacterial properties of herbal products and standard antibiotics. Aim: The aim is to investigate the effect of herbal products against standard antibiotics on bacteria growth. To examine the extent to which the herbal products (tea tree oil and peppermint oil) and the standard antibiotics (penicillin and streptomycin), reduce bacteria growth of E.coli and M.luteus. This will be discovered by measuring the growth of bacteria on the agar plates and comparing the results. Background information: The proposed aim surrounds the study of bacteria growth and various other products, which can have an affect on the growth rate; it is therefore necessary to look deeper into the topic criteria to get a wider understanding and to help design an appropriate hypothesis. From self-knowledge antibiotics are chemicals produced by microorganisms, which are designed to inhibit and destroy specific pathogens when used at low temperatures. Antibiotics release chemicals, which inhibit bacterial growth and work on a specific action site. The first founded antibiotic was penicillin discovered accidentally by Alexander Fleming in 1928 from a mold culture. It can be
Identifying an Ionic Compound. Objectives: To learn and test for metal ions and non-metal ions and then apply them to discover the identity of an unknown ionically bonded substance
Identifying an Ionic Compound- Introduction Ionic compounds are defined as being compounds where two or more ions (an atom or group of atoms with an overall electrical charge) are held next to each other by electrical attraction. One of the ions has a positive charge - called a "cation", and the other has a negative charge - called "anion". Cations are usually metal atoms and anions are either nonmetal or polyatomic ions (ions with more than one atom). Usually, when we have ionic compounds, they form large crystals that you can see with the naked eye. Table salt is one of this- if you look at a crystal of salt, you can see that it has in irregular cube shape. This is because salt likes to stack in little cube-shaped blocks. When forming salt, Na readily loses an electron and Cl readily gains an electrons so both can become stable. Heat is added in the reaction so Na burns brightly in CL gas and a white solid forms on the sides of the container. This solid is salt, or sodium chloride. When the chlorine atom gained an electron, the atoms arrange themselves in a lattice. The force of attraction between a cation and anion is a very strong bond called an "ionic bond". This is an electrostatic attraction. An ionic bond happens between a metal and a nonmetal. Properties of salts: 0. All ionic compounds form crystals. 0. Ionic compounds tend to have high melting and boiling
Assess the view that religion is a conservative force within society (40).
Assess the view that religion is a conservative force within society (40). A number of sociologists argue that religion is a conservative force in society, that is, it produces stability not change within society and it reinforces the shared needs and values of society. For some sociologists this is a positive effect - the view of consensus theorists, for others it is a negative one - the view endorsed by conflict theorists. Durkheim is a consensus theorist, sometimes referred to as the father of functionalism, he supports the view that religion is a conservative force in society, reinforcing the existing society of society. He argued that religion should not be explained in terms of human ignorance, but as a result of shared social needs. He adopted a broad definition of religion throughout his analysis and defined it as a unified belief system of beliefs about the nature of sacred things. For Durkheim, shared religious belief systems were central to societal consensus as they set rules for social interaction and offered social solidarity and value consensus. In his book, "Elementary Forms of Religious Life", he examined the sources of order and stability in society and highlighted the part that religion played in sustaining this order. Durkheim viewed religion as being a major source of social integration - all religious activity has one main function - the
