Question

The results of a study indicated that the correlation between a measure of children's helping behavior and the number of friends they had was .80. This correlation indicates that
a. helping behavior and number of friends are not related.
b. helping behavior and number of friends are negatively related.
c. the more helpful a child is, the more friends he or she has.

Answer 1

Answer:

c. the more helpful a child is, the more friends he or she has.

Explanation:

The correlation coefficient between measure of children's helping behavior and the number of friends is said to be 0.80. Assuming that the significance level is already met and here we only consider correlation coefficient, a correlation coefficient of more than 0.5 is considered a strong correlation. A correlation coefficient is between 0-1 and can have a positive or negative sign. 0 represent no correlation and 1 represents maximum correlation achievable. A minus (-) or negative sign means if one decreases, the other increases. A plus (+) or positive sign means if one increases, the other also increases. Here, it is +0.8 which means the more helpful a child is, the more friends he or she has.
