Research Methods

What is the main purpose of controlled experiments?

• To observe natural behaviors in uncontrolled settings

• To manipulate variables to observe effects on a dependent variable

• To compare different groups without any intervention

• To study long-term effects over decades

Which type of study is conducted in natural environments rather than a laboratory?

• Controlled Experiments

• Clinical Trials

• Field Experiments

• Cross-sectional Studies

In a double-blind study, who is unaware of the treatment assignments?

• Only the participants

• Only the researchers

• Both participants and researchers

• Only the data analysts

What is the focus of cross-sectional studies?

• Long-term effects over decades

• Data at a single point in time

• Manipulating variables in a lab

• Comparing different medications

Which study type involves monitoring a cohort of smokers?

• Cross-sectional Studies

• Longitudinal Studies

• Cohort Studies

• Field Experiments

What is the primary focus of theoretical studies?

• Non-numerical data analysis

• Mathematical modeling and simulation

• Random assignment in experiments

• Describing characteristics without causation
