B. a positive correlation.
C. a negative correlation.
D. a correlation coefficient that is less than zero.

Answer 1

Answer:

Positive Correlation

Explanation:

Correlation is a measure of relationship between two variables.

Positive Correlation: If variables move in same direction i.e one increase, other increase & one decrease, other decrease. Eg : Price & Supply

Negative Correlation: If variables move in opposite direction i.e one increase, other decrease & one decrease, other increase. Eg : Price & Demand

People tend to score low on one variable, tend to score low on other variable - signifies positive correlation between the two variable scores.
