Question

Dr. Ellison finds a relation between amount of sleep and problem solving. Specifically, having a higher amount of sleep the night before an exam is associated with higher scores on two measures of problem solving. This is an example of which type of association?

Answer 1

Answer:

Positive association

Explanation:

An association is the relation between two variables in an experiment.

In an experiment when increase in one of the variables causes the other variable to also increase it is known as positive association.

In an experiment when decrease in one of the variables causes the other variable to  increase it is known as negative association.

Here, higher amount of sleep results in higher scores in the test hence, this is a positive association.

Answer 2

Answer:

positive association

Explanation:

Positive association refers to the relationship developed between the two variables where the variables tend to move in the same direction. The condition specifies that with the decrease in one variable, the other variable decreases. On the other hand, when one variable increases, the other too increases. According to the given question, Dr. Ellison's research and study sets an example to be a positive association.
