Answer 12

External validity

Question 13

the degree to which changes in
the dependent variable across
treatment conditions were due
to the independent variable

Answer 13

Internal validity

Answer 14

1. History threat
2. Maturation threat
3. Testing threat
4. Instrumentation threat

7. Subject mortality threat
8. Selection interactions

Question 15

occurs when an event
outside the experiment threatens internal validity by changing the dependent variable

Answer 15

History Threat

Question 16

produced when physical or psychological changes in the subject threaten internal validity by changing the DV

Answer 16

Maturation Threat

Question 17

occurs when prior exposure to a measurement procedure affects performance on this measure during the experiment

Answer 17

Testing Threat

Question 18

when changes in the measurement instrument or measuring procedure threatens internal validity

Answer 18

Instrumentation Threat

Question 19

occurs when subjects
are assigned to conditions on the basis of extreme scores, and subjects are retested using the same procedure to measure change on the dependent variable

Answer 19

Statistical Regression
Threat

occurs when individual differences are not balanced across treatment conditions by the assignment procedure

Answer 20

Selection Threat

Question 21

occurs when subjects drop out of experimental conditions at different rates

Answer 21

Subject Mortality
Threat

Question 22

occur when a selection
threat combines with at
least one other threat

Answer 22

Selection Interactions
