Participants must be told enough about a study to decide whether to participate. 


What is informed consent

100

Combining results from many studies to find an overall effect.

What is a meta‑analysis

100

A study uses deception but explains everything afterward.

What is debriefing

100

A researcher manipulates noise level to test its effect on memory. Identify the research design.

What is an experiment 


100

A psychologist studies one rare case in depth.

Case study

200

Researchers must protect participants from physical or emotional harm. 


What is protection from harm

200

Meta‑analysis helps identify this across studies.

What are consistent patterns

A psychologist combines 40 studies on sleep and memory.

What is a meta‑analysis

200

A student remembers a list by grouping items. Identify the memory strategy.

Chunking

200

A participant is fully informed before participating.

Informed consent

300

Participants’ personal information must remain private.


What is confidentiality

300

The best measure of central tendency for a skewed distribution.

What is the median

What is the mode

300

A person believes they predicted an outcome after it happened.

Hindsight bias

300

Explain how random assignment increases internal validity.

It reduces pre‑existing differences/bias between groups (random assignment)

500

Explain how a variable affects another variable.

Cause‑effect reasoning
