What is a cause-and-effect relationship?

• A relationship between two or more variables

• A relationship where changes in one variable cause changes in the other variable

• A research design that can determine cause-and-effect relationships

• A type of observational study

What is a clinical or case study?

• A study that focuses on one or a few people

• A study that compares multiple segments of a population at a single time

• A study that determines cause-and-effect relationships

• A study that ignores evidence that disproves ideas or beliefs

What is confirmation bias?

• A tendency to ignore evidence that disproves ideas or beliefs

• A variable that affects both variables of interest

• A basis for comparison in an experiment

• A relationship between two or more variables

What is a confounding variable?

• A relationship between two or more variables

• An unanticipated outside factor that affects both variables of interest

• A variable that the researcher measures to see the effect of the independent variable

• A group that serves as a basis for comparison in a study

What is a control group?

• A relationship between two or more variables

• A group that serves as a basis for comparison in a study

• A variable that the researcher measures to see the effect of the independent variable

• An unanticipated outside factor that affects both variables of interest

What is correlation?

• A relationship between two or more variables

• A tendency to ignore evidence that disproves ideas or beliefs

What is a correlation coefficient?

• A number indicating the strength and direction of the relationship between variables

• A relationship between two or more variables

• A variable that the researcher measures to see the effect of the independent variable

What is cross-sectional research?

• A study that focuses on one or a few people

• A study that compares multiple segments of a population at a single time

• A study that determines cause-and-effect relationships
