When the values in one attribute tend to move in the same direction as the values in a correlated attribute, this is referred to as a __________ correlation.

• A. Positive
• B. Negative
• C. Zero
• D. Random

Answer: (A)

The main idea is how two attributes vary together. When values in one attribute tend to move in the same direction as those in the other, they are positively correlated. That means as one increases, the other tends to increase as well. For example, taller individuals often weigh more, so height and weight show a positive relationship on average. If the relationship went in opposite directions, it would be a negative correlation; if there’s no consistent pattern, we’d say there’s no correlation or zero correlation. So, moving in the same direction describes a positive correlation.
