Variable 1 = caffeine intake.

Variable 2 = exam stress.

What is a complex hypothesis?

A hypothesis involving three or more variables.

Extra: Example: Age, education level and health literacy are associated with medication adherence.

This hypothesis involves four variables.

What makes a hypothesis testable?

: Its variables can be observed, measured and analyzed.

Extra: Example: "Nicotine patches reduce daily cigarette consumption" is testable because cigarette consumption can be measured.

Can a hypothesis be both directional and simple?

Yes.

Extra: Example: "Nicotine patches increase smoking cessation."

It is directional because it predicts an increase and simple because it involves two variables.

After analyzing the data, how should researchers describe the status of a hypothesis?

Supported or not supported by the findings.

Extra: A single study does not establish absolute proof of a hypothesis.

What is the difference between a research question and a hypothesis?
