Consider the following scenario. Individuals that have negative Z score values on variable X also have negative Z score values on variable Y; and individuals that have positive Z score values on variable X also have positive Z score values on variable Y. Which type of correlation would you expect to find, given this scenario?
| Negative correlation coefficient |
| Zero correlation coefficient |
| Positive correlation coefficient |
Homework Answers
Answer
It is clear from the question that individuals that have positive z score values on variable X also have positive z score values on variable Y, this shows there is a positive correlation coefficient.
And individuals that have negative z score values on variable X also have negative z score values on variable Y, this shows there is a negative correlation coefficient.
But, we can never have negative and positive correlation coefficient for the same data set. So, we can say that there is no correlation or zero correlation between z scores on variable X and variable Y.
So, option B is correct answer

Consider the following information about variable X: Mean = 4, standard deviation = 2. Consider the following information about variable Y: Mean = 5, standard deviation = 3. If there is a correlation of r = 0.52 between variable X and variable Y, what is the intercept for a simple linear regression equation predicting Y on the basis of X? Please provide your answer as a raw score (not a z score) with a minimum of two decimal places.
