Which of these is NOT an experimental design?

• Field experiment

• Independent Measures

• Matched Pairs

• Repeated Measures

What is a weakness of Independent Measures design?

• Order effects

• Participant variability

• Practice effect

• Fatigue effect

Which experiment is the hardest to control variables?

• Lab

• Field

There will be a difference in the amount of words recalled from a list of 20 when participants do not have caffeine, compared to caffeine drinkers.

What type of hypothesis is this?

• Directional (one-tailed)

• Non-directional (two-tailed)

• Correlation

Why is it important to operationalise variables?

• So you know the researcher knows what they are doing.

• Easier to replicate the study

• Easy to read the study

What is a weakness of lab experiments?

• You can better control extraneous variables

• They are artificial (not like real life)

• You can manipulate the IV and measure the DV.

• You can't establish cause and effect.

What is a positive of a correlation study?

• You can use it when it isn't possible/easy to manipulate the IV

• You can establish cause and effect

• They are more efficient

• They show a relationship between two co-variables

A negative correlation is when...

• Both variables decrease

• Both variables increase

• One variable increases, the other decreases.

What is the purpose of a debriefing session?

• To collect additional data from participants.

• To inform participants about the study's objectives, provide an opportunity for questions, and address any potential negative consequences.

• To deceive participants further about the study's true nature.

• To obtain informed consent after the study is completed.

Which of the following is NOT a guideline for conducting ethical research with human participants?
