In two sets of variables x and y with 40 observationş each the following data were observed: Mean x series = 8 Mean y series = 4 Standard deviations of x series =2 Standard deviation of y series = 1 Co-efficient of correlation between x and y =+ 0.2 Further, it was later on found that one value of x=8 and one value of y = 4; were inaccurate and hence weeded out, with the remaining 39 pairs other values.
