GIVEN :

If bxy=0.25 and byx=0.64 then find the value of correlation  coefficient.

TO FIND :

The value of correlation  coefficient.

SOLUTION :

Given that the two regression coefficients are bxy=0.25 and  byx=0.64

The formula for correlation coefficient r when two regression coefficients  bxy and byx are given then :

r=\sqrt{bxy\times byx}

Substitute the values in the formula we get,

r=\sqrt{0.25\times 0.64}

=\sqrt{0.16}

=0.40

r=0.40

∴ The correlation coefficient r is 0.40

Option B) 0.40 is correct.
