• Focus groups, Experiments, Interviews.

Multiple Choice

"It is hypothesised that sleep deprivation will reduce academic performance".

In this hypothesis, the INDEPENDENT VARIABLE is:

• Academic performance

• Sleep quality

• Sleep deprivation

• Individual differences in students (abilities, interest in subject)

Multiple Choice

"It is hypothesised that sleep deprivation will reduce academic performance".

In this hypothesis, the DEPENDENT VARIABLE is:

• Academic performance

• Sleep deprivation

• Individual differences in students (abilities, interest in subject)

Multiple Choice

• The group with decaffeinated coffee.

  The group with caffeinated coffee.

• Those with a faster reaction time.

  Those with a slower reaction time.

• Those with a slower reaction time.

  Those with a faster reaction time.

Multiple Choice

Which type of extraneous variable:

One group of participants completes a mood survey in room 4, where there is a lot of distracting construction outside. The other group of participants completes it in the comfortable and quiet new year 7 building.

• Participant.

• Researcher.

• Situational.

• Methodological.

Multiple Choice

Which type of extraneous variable:

A female researcher is researching the impact of gender on memory. They show bias and favouritism towards the female participants.

• Participant.

• Researcher.

• Situational.

• Methodological.

Multiple Choice

Which type of extraneous variable:

When measuring the impact of caffeine on heart rate, it is evident that some participants have a naturally higher heart rate as they have improved cardiovascular fitness.

• Participant.

• Researcher.

• Situational.

• Methodological.

Open Ended

Identify one advantage with using an experimental design.

Open Ended

Identify one disadvantage with using an experimental design.

Multiple Choice

The main difference between observational studies and experiments is:

• The data in an experiment is quantitative.

• There is less control in an experiment.

• The IV is pre-existing in observational studies.

• The IV is pre-existing in experiments.

Multiple Select

Similarities between observational and experimental designs include (multiple answers):

• The data is quantitative.

• Each has a DV and an IV

• Both have random assignment to experimental / control groups.

• Causation can be inferred for both (cause-effect relationship)

Open Ended

Explain one disadvantage of observational studies.

Open Ended

Explain one diadvantage of observational studies.

Multiple Choice

The ideal number of participants in a focus group is:
