To see whether there is a correlation between the Maths marks and the English marks you can. Aimed at UK level 2 students on Access and GCSE Maths courses. A correlation coefficient measures the strength of that relationship. Study of such a graphical representation. A scatterplot displays the strength direction and form of the relationship between two quantitative variables. However if the scatter points are widely scattered throughout the line then the correlation is said to be low.
Many times executives assume andor presume that measures vary together when they do not.
A scatter diagram is given in the following example. Each xy variable is represented on the graph as a dot or a cross. Its this second class that well be focusing on in Chapter 4.
