The Use and Misuse of Figures and Statistical Analysis
[ send me this paper ]
This 20 page paper is written in four parts. Part one looks at a business proposal carries pout forecasts for the proposal of a new restaurant, showing how weekly, monthly and yearly forecasts can be made using excel. This section also shows the formula tables used for the projections. This section also considers the aspects which may not be including in financial proposals, such as stakeholder analysis and also the different between the flat rate and the annual percentage rate also known as the APR. The second part of the paper looks at time series data, what it is, how it can be used and presented using excel, and also the problems when using monetary time series data, explaining the difference between current and constant prices. Examples are given on this section. The third part of the paper looks at cross sectional data, what it is an how it can be used, an example is given. The example given is then analysed and the potential problems with this analysis are discussed. The last part of the paper explores correlation coefficients. Looking at what they are and how they may be used, as well as the way in which they maybe misused or misinterpreted. Examples are given to illustrate points raised. The bibliography cites 7 sources.
