Module 7 Research design

What is a research design?

• A plan to obtain answers to research questions

• A type of experiment

• A scientific theory

• A teaching method

What is one of the main functions of a research design?

• Create hypotheses

• Identify procedures and logistical arrangements

• Develop theories

• Collect data

What does it mean to operationalize variables?

• Define how they will be measured

• Create a control group

• Collect data

• Analyze results

What is a control group?

• A group of students

• A group of experts

• A group that receives the experimental treatment

• A group that does not receive the experimental treatment

What method is used to ensure that the control and experimental groups are comparable?

• Surveys

• Randomization

• Observation

• Interviews

What is sought by eliminating extrinsic variables?

• Reduce the sample size

• Isolate the impact of the independent variable

• Improve data collection

• Increase the complexity of the study

What should be done to obtain valid and objective answers?

• Publish the results

• Conduct surveys

• Conduct interviews

• Select an appropriate study design

What is meant by random variables?

• Variables that cannot be controlled

• Variables that are eliminated from the study

• Variables that can be measured

• Variables that are used in the analysis

What is sought when constructing an affecting variable in the study design?

• Improve data collection

• Reduce the sample size

• Increase the complexity of the study

• Isolate the impact of the variable

What should be done to ensure quality in research procedures?

• Follow a rigorous research design

• Conduct surveys

• Publish the results

• Conduct interviews
