Chapter 7

Question 1

It is the antecedent condition or treatment manipulated by the experimenter

Answer 1

Independent Variable

Question 2

It is the indicator of change in behaviour

Answer 2

Dependent Variable

Question 3

It defines exactly what was done to create the various treatment conditions of the experiment

Answer 3

Experimental Operational Definitions

Question 4

It specifies the procedures used to measure the impact of independent Variable

Answer 4

Measured Operational Definitions

Question 5

The degree to which scores on the measuring instrument correlate with another known standard for measuring the variable being tions in the experiment were actually caused by studied

Answer 5

Concurrent Validity

Question 6

An error that occurs when the value Interrater reliability The degree of agreement of an extraneous variable changes systematically along with the independent variable in an experi- ment; an alternative explanation for the findings that threatens internal validity

Answer 6

Confounding

Question 7

The degree to which an operational definition accurately represents the construct it is intended to manipulate or measure.

Answer 7

Construct validity

Question 8

measure reflects the content of what is being measured.

Answer 8

Content Validity

Question 9

A variable other than an independent or dependent variable; a variable that is not the focus of an experiment but can produce effects on the dependent variable if not controlled

Answer 9

Extraneous Variable

Question 10

The degree to which manipulation technique is evident

Answer 10

Face validity

Question 11

A threat to internal validity in which an outside event or occurrence might have produced effects on the dependent variable

Answer 11

History Threat

Question 12

Concepts used to explain
unseen processes, such as hunger, intelligence, or learning; postulated to explain observable behavior.

Answer 12

Hypothetical Construct

Question 13

A threat to internal validity produced by changes in the measuring instrument itself

Answer 13

Instrumentation threat

Question 14

The degree to which different items measuring the same variable attain consis tent results.

Answer 14

Interitem Reliability

Question 15

The certainty that the changes in behavior observed across treatment condition in the experiment were actually caused by the independent variable

Answer 15

Internal validity

Question 16

The degree of agreement among different observers

Answer 16

Interrater reliability

Question 17

An assessment to determine whether the independent variable was
manipulated successfully

Answer 17

Manipulation check

Question 18

Physical and psychological changes in subjects

Answer 18

Maturation threat

Question 19

A family of threats to produced by changes in the measuring instrument internal validity produced when a selection threat combines with one or more of the other threats to internal validity

Answer 19

Selection interaction
