Paper 3 Terms: Credibility

Question 1

Internal Validity

Answer 1

The procedural quality of the experiment; it is high when confounding variables are controlled, and researchers are sure the independent variable caused a change in the dependent variable. Internal validity is linked directly to bias—the less bias, the higher the internal validity.

Question 2

Controlling Confounding Variable

Answer 2

• Contributes to bias.
• They need to be controlled by eliminating them or keeping them constant in all groups of participants.

Question 3

Triangulation

Answer 3

Combines different approaches to collecting and interpreting data and checking with other sources.

Question 4

Method Triangulation

Answer 4

Using various methods to see if the same results are obtained.

Question 5

Researcher Triangulation

Answer 5

Combining the observations/interpretations of different researchers; if multiple people see the same thing, credibility increases.
