Question

Calculate the coficent of rank correlation from the following data.
X 76 72 64 69 67 70 61 65 58 57 54
Y 94 96 84 92 85 90 83 79 80 78 72

Answer 1

Answer:

Hint: To calculate the coefficient to correlation, we will be using Karl Pearson's coefficient of correlation which is given by rxy=n∑xiyi−∑xi∑yi√n∑xi2−(∑xi)2√n∑yi2−(∑yi)2.
