T.R. Jain and V.K. Ohri Solutions for Class 11 Statistics for Economics Chapter 12 – Correlation
From the following data, compute the Coefficient of Correlation between X and Y series:
|Number of items||6||6|
|Squares of Deviations from Mean||19||94|
The summation of the product of the deviations of X and Y series from their respective arithmetic mean is 41.
N = 6,
Substituting the values, we get
Coefficient of Correlation (r) = +0.97
