9.3.1.Example 1
The total length and standard lengths of 15 fishes of a particular species were measured. Work out the coefficient of correlation for the data given below:
Answer:
Then the Correlation coefficient is given by,
Interpretation
Since r = 0.99, we infer that there is high degree of positive correlation between total length (X) and standard lengths (Y) of 15 fishes of a particular species.
