What does 'randomization' refer to in experimental design?

Assigning participants to groups based on characteristics

Ensuring all groups have equal sample sizes

Assigning participants to groups by chance

Selecting the appropriate statistical test

What is the difference between an independent variable and a dependent variable?

Independent variable causes changes in dependent variable, dependent variable causes changes in independent variable

Randomly assigning participants to conditions

Systematically varying the order of conditions

#12

What is the purpose of blinding in experimental research?

To prevent bias in the interpretation of results

To ensure participants are unaware of the purpose of the study

To manipulate the independent variable

#13

What is the difference between reliability and validity in experimental research?

Reliability refers to consistency, validity refers to accuracy

Reliability refers to accuracy, validity refers to consistency
