From the picture, identify the correct experimental design.

What technique should a researcher use to allocate the sample of participants into each condition of an experiment. This should always be used for an independent groups and matched pairs design.

• Counterbalancing

• Random Allocation

• Participant Variables

• Sampling

Which experimental design could be affected by order effects, when a participants performance is affected by taking part in both conditions?

• Independent Groups

• Repeat Measures

• Matched Pairs

Which experimental design has the strength of reducing participant variables, although the variables are not completely removed?

• Independent Groups

• Repeat Measures

• Matched Pairs

Which of the following is an example of a null hypothesis?

• There will be no significant difference in reaction times (in seconds) after drink 30mg of caffeine compared to drinking water. Any difference will be due to chance.

• There will be a significant difference in reaction times (in seconds) after drink 30mg of caffeine compared to drinking water.

• Drinking 30mg of caffeine will increase reaction times (in seconds) compared to drinking water.

"Drinking 30mg of caffeine will increase reaction times (in seconds) compared to drinking water."

What is the operationalised independent variable in the hypothesis above?

• Time (in seconds)

• Caffeine (in mg)

• Reaction times

• The drink

Which of the following is not a true experiment?

• A laboratory experiment

• A field experiment

• A natural experiment

"A weakness of the experiment is that the high levels of control may reduce the validity of the findings. Participants may display demand characteristics or the behaviour may be too artificial."

A limitation of which type of experiment?

• Laboratory

• Field

• Natural
