If the X series denote experience and Y series denote performance and values of X series are 16, 12, 8, 9, 18, 9, 11, 16, 15, 3 and Y series are 23, 22, 24, 18, 16, 15, 28, 18, 25, 24. Find Karl Pearson's coefficient of correlation.
Using technology, the correlation coefficient value for the model whose data is given above is - 0.2245 which depicts that a weak negative relationship exists between the X series values varibale and Yseries variable. Our conclusion was inferred from the fact that - sign denotes negative and values close to zero denotes a weak association between the plotted variables.
