Quiz on Research Variables and Design

What are independent variables?

• Variables that are influenced by other variables

• Variables that do not change

• Variables that influence or cause other variables to change

• Variables that are controlled by the researcher

What do dependent variables represent?

• Variables that change in response to independent variables

• Variables that are held constant

• Variables that influence other variables

• Variables that are not measured

What are extraneous variables?

• Variables that are manipulated by the researcher

• Variables that influence the independent and dependent variables but are not part of the study

• Variables that are the main focus of the research

• Variables that are always measured

What is the purpose of a research design?

• To summarize the findings

• To identify the independent variable

• To outline the strategy for collecting and analyzing data

• To collect data only

Which of the following is a characteristic of true experimental designs?

• They are the weakest type of research design

• They do not require randomization

• They focus solely on qualitative data

What is the main focus of exploratory research designs?

• To test hypotheses

• To conduct surveys

• To analyze quantitative data

• To discover relationships among variables in real social structures

What does reliability in research refer to?

• The consistency of the research instrument

• The extent to which results can be generalized

• The accuracy of the research instrument

• The relevance of the research design

What is validity in research?

• The ability to replicate a study

• The accuracy of data collection methods

• The consistency of results over time

• The extent to which a measurement does what it is supposed to do

What is the purpose of a research proposal?

• To outline the researcher's intentions and significance of the study

• To collect data

• To analyze data

• To summarize findings

What should a good problem statement do?

• Avoid any technical terms

• Focus only on qualitative aspects
