Tutorial – Using Excel Data Forecasting Tools 

The table below shows the marketing expenditure and corresponding sales figures on a month by month basis for SM Heating Products. 

You are asked to produce an analysis of these figures for inclusion in a report to be presented to the board of directors. In doing this you will need to establish trends over the period shown for both expenditure and revenue and determine the relationship between these. This will require the use of statistical analysis tools available in Excel. 

You will need to select appropriate trend-lines and relationship functions to bring the data into an understandable form. You must justify your selection. 

Finally you should write a short summary of the technique used in the analysis and critically evaluate your results.
