Which statement is the non-directional hypothesis?

• To investigate whether there is gender difference in judging the speed of a car.
• Males are more accurate in judging the speed of a car than females.
• There is a difference in accuracy of judging the speed of a car between males and females.
• Females are more accurate in judging the speed of a car than males.

An experiment investigated whether close proximity to strangers increased heart rate. The DV would be:

• Proximity of strangers.
• The strangers.
• Heart rate.
• The participants. 

Which would not be an effective way of operationalising aggression?

• Number of punches thrown.
• Number of expletives used.
• Distance someone stood from someone else.
• Facial Expressions.

An effective experimental hypothesis should include:

• A clearly operationalised co-variable.
• A clearly operationalised DV.
• A clearly operationalised EV.
• A clear aim.

Which best describes a confounding variable?

• Any variable, other than the IV, that may have systematically affected the DV.
• Any variable that may potentially affect the IV or DV.
• Any cue from the researcher or research situation that may reveal the aims of the study.
• Any effect of the investigator's behaviour that may affect the outcome of the research.

'Individual differences between participants that may affect the DV' best describes which of the following?

• Extraneous variables
• Confounding variables
• Situational variables
• Participant variables

The use of chance in order to control for the effects of bias best describes which of the following?

• Situational Variables
• Demand Characteristics
• Standardised Instructions
• Radomisation.

Standardisation is useful when it comes to investigations being...

• Reinterpreted
• Replicated
• Complicated
• Estimated

An experiment that measured the effects of an earthquake on stress levels (measured before and after) would be a:

Which would not be classed as a 'true' experiment?

• Lab experiment
• Quasi-experiment
• Controlled experiment
