A correlation of r = +0.7 between gender and height.

Information For each of Questions 1 to 5, is the given value of the correlation coefficient reasonable? Hint: think about the strength and the direction of the relationship between the two variables in each case. Note: It is subjective to decide whether the magnitude of the correlation between two variables should be, for example, 0.7 or 0.8. The below questions don't ask you to make a decision like this. Question 1 A correlation of r = +0.7 between gender and...

Suppose the correlation between first year GPA and second year GPA is 0.7. Assuming a close to linear relationship between GPAs in first year and in second year, what is the approximate average z-score in second year of students who had a z-score of 1.5 in their first-year GPA? What is the average first-year z-score of students who have a z-score of 1.5 in their second-year GPA? It seems that, on average, students who do well in first year do...

A researcher finds a correlation of .76 between a husband’s flexibility in his gender role and a wife’s degree of martial satisfaction. Based on this correlation, we can explain or predict how much of the variability in marriage satisfaction scores by a husband’s score on flexibility in gender roles? What other factors may potentially account for the unexplained variance in marriage satisfaction?
