Research Study Design Quiz

What is the main goal of a qualitative study?

• To make generalizations about a population

• To quantify relationships

• To explore experiences and gain insights

• To test hypotheses

In a case-control study, the group without the outcome of interest is called:

• Experimental group

• Control group

• Comparison group

• Intervention group

What is the key advantage of a randomized controlled trial (RCT)?

• Quick and cheap

• Unbiased distribution of confounders

• May include researcher bias

• Relies on non-numerical data

What is the purpose of a meta-analysis?

• To explore experiences and gain insights

• To conduct an experimental comparison study

• To combine results from multiple studies

• To follow a subset of a defined population

In a cross-sectional study, data is collected at:

• Over time as characteristics change

• Follow-up for 2 or more visits

• One point in time

• Multiple time points

What is the main limitation of a randomized controlled trial (RCT)?

• Ethically problematic at times

• Volunteer bias

• Cannot be done for ethical reasons in certain cases

• Expensive: time and money

What is the purpose of a cohort study?

• To establish causality

• To compare treatment groups

• To evaluate the relationship between early growth and age-related disorders

• To conduct an experimental comparison study

What is the distinguishing feature of a double-blind study?

• Randomization to exclude unknown influencing factors

• Randomization of the target group

• Blinding more likely

• Investigators and participants are unaware of group assignments

What type of study design is best for evaluating the effect of an intervention?

• Cross-sectional study

• Cohort study

• Randomized controlled trial

• Case-control study

What is the purpose of a systematic review?

• To conduct an experimental comparison study

• To combine results from multiple studies

• To explore experiences and gain insights

• To follow a subset of a defined population
