From the picture, identify the correct experimental design.

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.

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

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

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

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

What is the operationalised independent variable in the hypothesis above?

Which of the following is not a true 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?

"Participants behave differently to a natural situation because they are aware they are being studied or know the aim of the study"

"When a study is replicated and achieve consistent results or findings."

What name is given to the variables that could affect the dependent variable other than the independent variable?

What technique describes when a researcher and participant both do not know the aim of the study. The technique increases objectivity and control.

What is the correct name for the set of instructions that an experiment must follow. This ensures every participant is treated the same, whilst allowing other researchers to replicate the study.
