QUESTION 8 Making a scatter diagram before figuring the correlation coefficient is a good idea because O there is no point in figuring the correlation if a clear line is formed on the graph O there are different procedures depending on whether there appears to be a positive or a negative correlation O it allows estimation of the degree and direction of correlation to provide a check on eventual figuring. O a correlation coefficient should only be figured if a clear curvilinear correlation is seen.
