Randomized Control Trial in Research

What is a randomized control trial (RCT) in research?

• A type of scientific experiment to test the effectiveness of new treatments or interventions

• A type of art exhibition to test new paintings

• A type of cooking competition to test new recipes

• A type of dance competition to test new choreography

What are the key features of a randomized control trial?

• Not blinding participants and researchers to treatment allocation

• Using only one group for the study

• Assigning participants to groups based on their preference

• Random assignment of participants to different groups, use of control group for comparison, and blinding of participants and researchers to treatment allocation

Why is randomization important in a randomized control trial?

• Randomization helps to minimize bias and ensure that the treatment groups are comparable.

• Randomization can lead to unequal treatment groups and skewed results

• Randomization is not important in a randomized control trial

• Randomization only adds unnecessary complexity to the study

What are the advantages of using a randomized control trial in research?

• Randomized control trials have no impact on establishing cause and effect relationships

• Randomized control trials increase bias and reduce internal validity

• Randomized control trials help in establishing cause and effect relationships, minimize bias, and provide high internal validity.

• Randomized control trials are time-consuming and expensive

What are the limitations of using a randomized control trial in research?

• Informed consent, confidentiality, and data security

• Participant bias, researcher bias, and funding

• Sample size, data collection, and analysis

• Ethical concerns, practicality, and generalizability

What is the role of blinding in a randomized control trial?

• Minimize bias and prevent participants or researchers from knowing which treatment group they are in.

• Increase bias and allow participants to know which treatment group they are in.

• Have no impact on bias and allow researchers to manipulate the results.

• Maximize bias and ensure that participants are aware of the treatment group they are in.

What are the ethical considerations in conducting a randomized control trial?

• Violating confidentiality

• Ignoring informed consent

• Maximizing harm

• Obtaining informed consent, minimizing harm, ensuring confidentiality, and maintaining integrity

How is the sample size determined in a randomized control trial?

• Coin flip

• Statistical power analysis

• Random guessing

• Magic 8 ball

What are the different phases of a randomized control trial?

• Preparation, Execution, Review, Approval

• Recruitment and randomization, Observation, Conclusion

• Screening, Placebo, Observation, Data collection

• Recruitment and screening, Randomization, Intervention, Follow-up, Analysis

What are the steps involved in analyzing the results of a randomized control trial?

• Data collection, statistical analysis, interpretation of findings, and drawing conclusions

• Data analysis, hypothesis testing, and data visualization

• Interviewing participants, survey design, and data presentation

• Literature review, data entry, and data cleaning
