Interpretation: Degree of agreement between the referees ‘A’ and ‘B’ is 0.636

and they have “strong agreement” in evaluating the competitors.

Properties of coefficient of correlation: -

1. The value of coefficient of correlation always varies in between +1 & -1
including both the limits.
2. The coefficient of correlation is independent of change of origin and scale
of measurements.

3. If two variables are independent then coefficient of correlation will be
equal to zero.
4. Coefficient of correlation is a unit free measure.
5. Coefficient correlation between x and y is equal to coefficient of correlation
between y and x. i.e. = .

6. The coefficient of correlation is a measure of linear ship.
