- A scatter graph is a graph that comprises of points which have been plotted but are not joined through line segments
- The pattern of the points will definitely reveal the types of relationship existing among variables
- Given sketch graphs will greatly assist in the interpretation of scatter graphs.
NB: For the above diagram, this is referred to as perfect since the points may easily be represented by a single line graph for illustration when measuring relationship among volumes of sales and profits in a company, the more the company sales the higher the profits.
This illustration considers volume of sale in relation to the price, the cheaper the goods the bigger the sale.
