Q2.If two variables are highly correlated, what do you know?

High degree of correlation implies that there is a strong relationship between the two variables and that the changes in one variable cause predictable changes in the other variable.
Q3.If paired scores occupy the same positions within their own distributions (high with high and low with low)
Answer : Option BExplaination / Solution:
If high scores on one variable are paired with high scores on other variable and low scores are paired with low scores, correlation will be high and therefore Pearson's r will be high and positive.
