Which of the following correlation coefficients is less likely to occur? 0 a. -.54
O b. + .22
O c. -0.78
O d. +.16

c. -0.78

Explanation:

Correlation coefficients are used to measure the relationship between two variables.  correlation coefficients lies between -1 and +1.

Correlation coefficients greater than zero indicates positive correlation, less than zero indicates negative correlation and zero shows no relationship between the two variables.

Large positive or negative correlations have very less chances to occur, so large negative correlation will have less chances to occur because sampling variation gives large negative correlation by chance.

Hence, the correct answer is c. -0.78.
