Research Methodology Quiz

What is the purpose of descriptive research design?

• To measure the degree of association between two or more variables

• To manipulate conditions and study effects

• To establish cause-effect relationships by comparing groups

• To describe systematically the facts and characteristics of a given population or area of interest

What is the main characteristic of convenience sampling?

• It involves selecting individuals or schools who are representative of the population

• It requires randomly assigning participants to different conditions of the experimental variable

• It includes assignment, but not random assignment of participants to groups

• It involves selecting a group of individuals who are conveniently available for study

What is the purpose of purposive sampling?

• To select individuals or schools who are representative of the population

• To select a group of individuals who are conveniently available for study

• To draw randomly from a list of the population

• To use researcher's judgment to select a sample that they believe will provide the data they need

What is the main purpose of content validation for an instrument?

• To establish the stability and consistency of the scores from the instrument

• To develop sound evidence to demonstrate that the test interpretation matches its proposed use

• To measure the extent to which the test measures a theoretical construct or trait

• To establish the extent to which the content or topic of the test is truly representative of the content of the course

What is the main purpose of Cronbach's alpha test for reliability?

• To compute the average value of the reliability coefficients for all possible combination of items when split into two half tests

• To measure the extent to which the test agrees or correlates with a criterion set up as an acceptable measure

• To determine the degree to which the test interpretation matches its proposed use

• To establish the extent to which the content or topic of the test is truly representative of the content of the course

What is the main purpose of quasi-experiments in research design?

• To include assignment, but not random assignment of participants to groups

• To determine the extent to which two variables co-vary

• To test an idea to determine whether it influences an outcome

• To establish cause-effect relationships by comparing groups

What is the main purpose of longitudinal survey designs?

• To establish cause-effect relationships by comparing groups

• To collect data about trends with the same population over time

• To describe and measure the degree of association between two or more variables

• To examine current attitudes, beliefs, opinions, or practices

What is the main purpose of correlational research design?

• To test an idea to determine whether it influences an outcome

• To determine the extent to which two variables co-vary

• To establish cause-effect relationships by comparing groups

• To describe and measure the degree of association between two or more variables

What is the main purpose of causal comparative research design?

• To determine the extent to which two variables co-vary

• To test an idea to determine whether it influences an outcome

• To describe and measure the degree of association between two or more variables

• To establish cause-effect relationships by comparing groups

What is the main purpose of experimental research design?

• To establish cause-effect relationships by comparing groups

• To describe and measure the degree of association between two or more variables

• To determine the extent to which two variables co-vary

• To test an idea to determine whether it influences an outcome
