Explanation

Public annual reports can be a source of information that helps the procurement professional to analyse an industry's cost and revenue using the line of best fit. Line of best fit is one of the most important outputs of regression analysis. Regression refers to a quantitative measure of the relationship between one or more independent variables and a resulting dependent variable. Regression is of use to professionals in a wide range of fields from science and public service to financial analysis.

In this case, by collecting and analysing 17 annual reports, the procurement manager can find the line of best fit which goes approximately through the middle of the data points with an equal num-ber of data points above and below it.

The slope of the line of best fit is the approximate variable costs the industry. The easiest way to calculate it is to take a point at the right-hand end of the line of best fit and note its cost and output levels. Divide the cost by the output and this gives and approximate figure for the cost per unit of output or variable cost. This gives an approximate value for the industry fixed and variable costs.

Explanation
