Play an AI-generated podcast conversation about this lesson

What is the primary concern when assessing associations between variables in research?

The presence of an association (correct)

The type of association

The magnitude of the association

The direction of the association

What is the null hypothesis stating in a given research scenario?

The association is only present in the sample

There is a moderate association between the variables

The variables are not linked in the population (correct)

There is a significant association between the variables

What is the main goal of statistical hypothesis testing in research?

To infer whether an association exists or not in the population (correct)

To determine the direction of an association

To determine the magnitude of an association

To determine the type of association
