Research Methods Test Questions With Complete Solutions 2024 Update Rated A+ What is the independent variable in an experiment? the variable that is manipulated/changed by the researcher What is a dependent variable in an experiment? the variable that is measured by the researcher what is operationalisation? Clearly defining variables in terms of how they can be measured What is an extraneous variable? any other variables apart from the independent variable that MIGHT have an effect on the dependent variable. What is a confounding variable? when a extraneous variable is not controlled by the experimenter meaning we cannot establish cause and effect what are the 3 extraneous variables? participants, situational and investigator effects what is a participant variable? the different characteristics of an individual that may influence the study what is a situational variable? These are aspects of the environment/situation that might affect the participant's behaviour, e.g. noise, temperature, lighting conditions, etc. what is an investigator effect? any unwanted effects of the investigators behaviour and influence on the research's outcome. What are demand characteristics? when participants change their behaviour as a result of being in an experimental situation how do you control for extraneous variables? randomisation, standardisation and double blind procedure what is randomisation? Randomisation is the random allocation of participants to conditions to help control for variation due to participants. what is standardisation? Using exactly the same formalised procedures and instructions for all participants in a research study.
