Cards in this deck (17)
- 1Independent VariableA controlled variable that effects any other variables.
- 2Dependent VariableThe variable that is affected by the IV and is measured.
- 3HypothesisA prediction of what effect the IV will have on the DV, if any.
- 4Directional HypothesisThe IV will have a specific effect on the DV. It will tend to use words such as 'increase' or 'less than'.
- 5Non-Directional HypothesisThe IV will have an effect on the DV, but it is not clear what sort of effect.
- 6Null HypothesisThe IV will have no effect on the DV.
- 7Example: DirectionalChildren that drink milk will be taller than those who don't.
- 8Example: Non-DirectionalDrinking milk will affect height.
- 9Example: NullDrinking milk will have no effect on child's height.
- 10OperationalizationClearly defining variables in a way that allows them to be measured.
- 11Example: OperationalizationDrinking 200ml of milk will make you grow taller than those who don't drink any milk.
- 12Extraneous VariableA variable, other than the IV, that affects the DV, and is easy to control.
- 13Confounding VariableA variable related to the IV that is not being studied, but still affects the DV. It is not easy to control.
- 14Demand CharacteristicWhen a participant in a study realizes what the study is about, through some way or another, and subconsciously changes their behavior to meet the requirements of the study.
- 15Investigator EffectWhen the investigator acts in a way, whether unconscious or not, that supports their hypothesis, creating bias and affecting the results of the experiment.
- 16RandomizationUsing chance to assign conditions or variables to participants.
- 17StandardizationProviding each participant with the exact same environment, stimulus, instructions etc. to get an unbiased result.
