Question

A recent study (in Behavior Modification, vol. 29, 2005, p. 677) reported a correlation of 0.68 between scores on an index of depression and scores on an index that measures the amount of saturated fat intake. True of false: You can conclude that if you increase your saturated fat intake by a standard deviation, your degree of depression will increase by more than half a standard deviation.

Answer 1

we know that the relationship between correlation coefficient and standard deviation is given as

Since the correlation is positive value, this means that increase in independent variable will result in increase in depedent variable.

independent variable is saturated fat intake and dependent variable is degree of depression

So, when there is an increase in saturated fat intake then this will increase the degree of depression.

Answer is TRUE
