Business Studies Assessment 2 – Adam Denny

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 buying each other gifts, and dip in January when (generally) consumers have less money due to spending so much on presents, and figures could be devised to estimate how many units will need to be produced. This allows Nintendo’s operations department to build up ...

Here's what a star student thought of this essay

The spelling and grammar was very good. I do not think there were any errors. The layout was fantastic, as each point of analysis was in its own paragraph, doing this is thoroughly recommended, as it makes the essay easier to read. The author uses good connective words as well, which give a good balance to essay, which is vital in business studies/ economics essays, an example of the connective would be: Ã¢â‚¬ËœOn one sideÃ¢â‚¬Â¦.but on the other.Ã¢â‚¬â„¢ This essay received all five stars, for having great analysis, good spelling and grammar, and having a balanced approach.

The level of analysis was good as well, as the author went in to some depth looking at the pros and cons of each method. Praise is due for not just saying what each method was, as there is a danger in these sorts of questions of describing, but actually analyzing. He improved his analysis substantially by using own knowledge, as it increased the level of depth they could go into. Another good thing to take away from this essay was the authorÃ¢â‚¬â„¢s use of an imaginary example to help explain some of his/herÃ¢â‚¬â„¢s analysis, namely the example of using a bundle promotion. The use of a graph was very good as well as it gave the reader an exact idea of what they were discussing.

The author answers the question fantastically well. As he clearly sets out the pros of using correlation and extrapolation and highlights the cons as well, whilst using his/hers own knowledge of the industry to improve his points. Using own knowledge is very good, for instance the author highlighted the industry as oligopolistic; as it shows you have a good understanding of the topic and that you are Ã¢â‚¬Ëœkeen.Ã¢â‚¬â„¢ The essay starts very well, due to the fact he defined the two techniques in the question, whenever you get an essay (can be any essay) always try to define the key terms and assess what the question is asking, which the author does. He concludes the essay, exceptionally, by bringing all the points he/she made in the essay together. In business studies essays it is important to have a balanced approach, so as to seem impartial and neutral, you shouldnÃ¢â‚¬â„¢t be trying to force your argument, but to convey the data in a way that forms an argument, this is something the author does very well, as he/she doesnÃ¢â‚¬â„¢t just say Ã¢â‚¬Ëœextrapolation is the best because it can be accurateÃ¢â‚¬â„¢ but says that they can be good, but they do have their draw backs (good examples of this in last three paragraphs.)
