A2 Hypothesis and vars
Cards in this deck (16)
- 1AImgeneral statement describing the purpose
- 2Hypothesisa testable statement that clearly states the difference or relationship betw variables on the outset
- 3Directional hypothesisdirection of rel is specified
- 4Non-directional hypothesisDirection of rel is not specified
- 5When are directional hypo is used and non-direction used?Dir: when prev research findings suggest a particular outcome
Non-dir: contradictory/ or none - 6Variables (2)Any thing that can vary or change within an investigation
Used in experiments to det if change in one var causes change in the other - 7IVexpt situation that is manipulated so effect on DV can be measured
- 8DVvar that is measured and caused by change in IV
- 9OperationalisationMaking the variables measurable by clearly defining them
- 10Extraneous variablesAny var other than IV that may have an effect on DV
- 11What is the opposite of confounding variable and define itNuisance variables: Straightforward to control bc does not vary systematically with IV
- 12Demand chars + why this is problematicany cues in the research env that are interpreted as revealing the purpose of the investigation by the ppt
Ppts' beh no longer become natural - 13Investigator effect + 3 examplesAny effect of the investigator's beh either consc or unconsc on the research outcome
E.g. selection of ppts, research design, instructions - 14Two ways of controlling extraneous vars and ppt reactivityrandomisation
standardisation - 15What is randomisation + what is being controlleduse of change to control the effects of bias when designing the investigation and materials
Investigator effects - 16What is standardisation + what is being controlledUsing exactly the same formalised procedures and instructions for all ppts Reduces extraneous vars
