What is a matched pairs design experiment?

Back

A matched pairs design experiment is a type of experimental design where participants are paired based on certain characteristics, and each member of the pair receives a different treatment. This design helps control for variables that could affect the outcome.

Front

What is a response variable?

Back

A response variable is the outcome or effect that is measured in an experiment. It is the variable that researchers are interested in explaining or predicting.

Front

What is a lurking variable?

Back

A lurking variable is a variable that is not included in the study but can affect the results. It can confound the relationship between the explanatory and response variables.

Front

What is an explanatory variable?

Back

An explanatory variable is a variable that is manipulated or categorized to observe its effect on the response variable.

Front

What is the difference between an observational study and an experiment?

Back

An observational study involves observing subjects without manipulating any variables, while an experiment involves manipulating one or more variables to determine their effect on a response variable.

Front

What is a randomized comparative experiment?

Back

A randomized comparative experiment is an experimental design where subjects are randomly assigned to different treatment groups to compare the effects of the treatments.

Front

What is the purpose of a control group in an experiment?

Back

The control group serves as a baseline to compare the effects of the treatment. It does not receive the treatment being tested.

Front

What is the significance of randomization in experiments?

Back

Randomization helps eliminate bias by ensuring that each participant has an equal chance of being assigned to any group, which helps to ensure that the groups are comparable.

Front

What is a block design experiment?

Back

A block design experiment is an experimental design that involves dividing subjects into blocks based on a certain characteristic and then randomly assigning treatments within each block.

Front

How do you identify the response variable in a study?

Back

The response variable is identified by determining what outcome is being measured or observed in the study.
