Observation: Identify a problem or question based on observations of the natural world.

Research: Conduct background research to gather information about the topic.

Hypothesis: Formulate a testable hypothesis that explains the observed phenomena.

Experiment: Design and conduct experiments to test the hypothesis. Collect and analyze data.

Conclusion: Draw conclusions based on the results and determine whether the hypothesis is supported or refuted.

Communication: Share findings through scientific publications or other means

Answer 15

Survey: Collects data via survey instruments  Example: Use of dietary supplements via a questionnaire
Observational: Indicate relationships among health phenomena of large populations; does not prove causation  Example: Smoking status and sleep outcomes
Epidemiological: Examine patterns of health and disease in defined populations  Example: Looking at global incidence of Type II diabetes over 5 years
Case Study: Observational studies that compare groups with and without a condition  Example: Sleep outcomes in 50 seniors with hypertension compared to 50 seniors without hypertension

Question 21

Independent Variable:

Answer 21

Variable that is manipulated to explore its effects.
Intervention given
Independent = NOT influenced

Question 22

Dependent Variable:

Answer 22

Variable that is not manipulated
Changes as a result of the independent variable
It is dependent upon the independent
Outcome a study is interested in
Dependent = Influenced
