Question

Height and weight are positively correlated. This means that: a. There is no relationship between height and weight. b. Usually, the taller someone is, the thinner they are. c. Usually, the shorter someone is, the heavier they are. d. As height increases, typically weight increases.

Short answer

The correct answer is choice 'd' which states 'As height increases, typically weight increases'.

Step-by-step solution

Understanding Positive Correlation

In statistics, when two variables are positively correlated, it means that when one variable goes up, the other variable typically also goes up. In other terms, they move in the same direction.

Understanding the Four Choices

Look at each of the four answer choices and compare them with the definition of positive correlation. Evaluate whether the statements describe a situation where one variable increases as the other variable increases.

Choose the Correct Answer

Choice 'd' states: 'As height increases, typically weight increases.' This statement aligns with the definition of positive correlation and is therefore the correct answer.
