variables Flashcards
1
Q
operationalizing variables
A
This means clearly describing the variables (IV and DV) in terms of how they will be manipulated (IV) or measured (DV).
2
Q
independent variable
A
variable that the experimenter manipulates (changes)
3
Q
dependent variable
A
variable that is measured to tell you the outcome
4
Q
extraneous variable
A
Variables that if not controlled may affect the DV and provide a false impression that an IV has produced changes when it hasn’t.
5
Q
confounding variables
A
- a third variable that influences both the independent and dependent variables
- Failing to account for confounding variables can cause you to wrongly estimate the relationship between your independent and dependent variables.
