variables

Question 1

operationalizing variables

Answer 1

This means clearly describing the variables (IV and DV) in terms of how they will be manipulated (IV) or measured (DV).

Question 2

independent variable

Answer 2

variable that the experimenter manipulates (changes)

Question 3

dependent variable

Answer 3

variable that is measured to tell you the outcome

Question 4

extraneous variable

Answer 4

Variables that if not controlled may affect the DV and provide a false impression that an IV has produced changes when it hasn’t.

Question 5

confounding variables

Answer 5

• 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.
