What is the variable that the researcher measures in an experiment for changes it may experience due to the effect of the independent variable?

• Independent variable

• Controlled variable

• Dependent variable

• Experimental group

What is a controlled experiment?

• An investigation in which the causal relationship between two variables is tested in a controlled environment

• The process of collating and analysing secondary data related to other people’s scientific findings

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

• To receive the experimental treatment

• To serve as a baseline for comparison

• To manipulate the independent variable

• To measure the dependent variable

What is a within-subjects design?

• An experimental design in which participants complete every experimental condition

• A type of non-experimental study in which researchers observe and measure the relationship between two or more variables

• The process of collating and analysing secondary data related to other people’s scientific findings

• The construction and/or manipulation of either a physical model or a conceptual model

What is a between-subjects design in experimental research?

• An experimental design in which individuals are divided into different groups and complete only one experimental condition

• An experimental design in which individuals participate in all experimental conditions

• An experimental design that combines elements of within-subjects and between-subjects designs

• An experimental design that uses random sampling techniques

What is the main characteristic of convenience sampling?

• Selecting readily available members of the population

• Ensuring every member of the population has the same chance of being selected

• Selecting people from the population in a way that ensures proportional representation

• Using a random or systematic approach
