methods


IV - CORRECT ANSWERS ✔✔The variable that is manipulated by
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


the researcher to see if it effects the DV.
|\ |\ |\ |\ |\ |\ |\ |\




DV - CORRECT ANSWERS ✔✔The variable that the researcher
|\ |\ |\ |\ |\ |\ |\ |\ |\


measures.


Co-Variables - CORRECT ANSWERS ✔✔The two variables
|\ |\ |\ |\ |\ |\ |\


measured in a correlation study |\ |\ |\ |\




Operationalisation - CORRECT ANSWERS ✔✔Defining variables in |\ |\ |\ |\ |\ |\ |\


form so they can be easily manipulated or measured e.g. the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


operationalisation of intelligence as in IQ score. |\ |\ |\ |\ |\ |\




Extraneous Variables - CORRECT ANSWERS ✔✔Variables in a
|\ |\ |\ |\ |\ |\ |\ |\


study that are not being manipulated or measured by the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


researcher but affect the results (DV) of all the participants'
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


behaviour equally. |\




Confounding Variables - CORRECT ANSWERS ✔✔Variables in a
|\ |\ |\ |\ |\ |\ |\ |\


study that aren't being manipulated or measured by the
|\ |\ |\ |\ |\ |\ |\ |\ |\


researcher that affect some of the participants' behaviours but
|\ |\ |\ |\ |\ |\ |\ |\ |\


not others.
|\

, Situational Variables - CORRECT ANSWERS ✔✔Factors in the
|\ |\ |\ |\ |\ |\ |\ |\


environment that can unintentionally affect the DV in a study e.g.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


noise, temperature, lighting or time of day.
|\ |\ |\ |\ |\ |\ |\




Dealing with Situational Variables - CORRECT ANSWERS ✔✔Dealt
|\ |\ |\ |\ |\ |\ |\ |\


with using standardised procedures ensuring that all participants
|\ |\ |\ |\ |\ |\ |\ |\


are tested under the same conditions. Therefore the environment
|\ |\ |\ |\ |\ |\ |\ |\


is controlled.
|\ |\




Participant Variables - CORRECT ANSWERS ✔✔Individual
|\ |\ |\ |\ |\ |\


characteristics of each participant that may impact how he or |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


she responds e.g. mood, anxiety or intelligence
|\ |\ |\ |\ |\ |\




Dealing with Participant Variables - CORRECT ANSWERS ✔✔Dealt
|\ |\ |\ |\ |\ |\ |\ |\


with using repeated measures design or matched pairs design
|\ |\ |\ |\ |\ |\ |\ |\ |\


which matches the participants on abilities, backgrounds and
|\ |\ |\ |\ |\ |\ |\ |\


characteristics.


Researcher Effects - CORRECT ANSWERS ✔✔When a researcher
|\ |\ |\ |\ |\ |\ |\ |\


unintentionally or intentionally influences the outcome of any |\ |\ |\ |\ |\ |\ |\ |\


research they are conducting. Example 1 - Non-verbal
|\ |\ |\ |\ |\ |\ |\ |\


Communication e.g. facial expression. Example 2 - Physical |\ |\ |\ |\ |\ |\ |\ |\


Characteristics e.g. gender. Example 3 - Bias in Interpretation of |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


Data.


Dealing with Researcher Effects - CORRECT ANSWERS ✔✔Dealt
|\ |\ |\ |\ |\ |\ |\ |\


with using a double-blind design meaning both the participant
|\ |\ |\ |\ |\ |\ |\ |\ |\


and person conducting the study don't know the aims therefore
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


the researcher can't affect the results.
