A developmental psychologist is analyzing a dataset of participants' heights and weights. Because these two variables typically exhibit a positive correlation, if a participant's height is recorded as significantly above average, the researcher should expect their weight to generally be below average.

In the classic example of a positive correlation between height and weight, the two variables change in opposite directions.
In psychology research methods, the relationship between height and weight is a classic example of a positive correlation. Match each concept or variable trend with its correct statistical interpretation to demonstrate your understanding of this relationship's behavior.
A researcher partitions a height-weight dataset into four height quartiles and computes the mean weight for each quartile. She observes that mean weight increases monotonically from the lowest to the highest height quartile. By decomposing the data this way, she concludes that height and weight exhibit a _____ correlation, because the two variables consistently change in the same direction.

Using the classic example of a positive correlation between height and weight, write 1-3 sentences predicting how a child's weight would statistically be expected to change as they grow taller, and state the direction of change for both variables.
Which of the following correctly describes the positive correlation typically observed between an individual's height and weight?
Because height and weight share a positive correlation, a taller individual will always weigh more than a shorter individual.
