observed
Control Variable is ___
held constant
Other Terms for IV
- treatments
- manipulations
- interventions
- conditions
Other Terms for DV
- measures
- effects
- outcomes
- results
factors being manipulated by the experimenter, and are chosen because they are believed to influence behavior
Independent Variable
where the independent variable fails to control behavior
Null Results
Null Results is where the independent variable fails to control behavior, and could mean the following:
1) Variable was __ ___
2) Manipulation was __ ___
1) not important
2) not effective
Psychological experiments typically manipulate __ to ___ independent variables simultaneously for efficiency and better control.
two to four
Sometimes aspects of the physical environment that can be brought under the experimenter’s direct control are ___ and ___ :
1) Lighting (bright or dim)
2) Noise levels (loud or soft)
response being measured based on experimenters manipulation
Dependent Variable
The dependent variable measures ____ and ___, allowing for scoring in experiments.
behavior and performance
considered as a crucial criterion for a good DV, ensuring consistency upon repetition.
Stability
where variable gets stuck at the lowest/highest possible value, hindering the observation
“Floor” & “Ceiling” Effect
potential independent variable that are kept constant during an experiment
Control Variable
