A : true
B : false<\/p>\n\n\n\n
Correct Answer : A
16 : If a researcher measures two individuals on a nominal scale, it is impossible to determine
which individual has the larger score.
A : true
B : false
Correct Answer : A
17 : If a researcher measures two individuals on an ordinal scale, then it is impossible to
determine how much difference exists between the two people.
A : true
B : false
Correct Answer : A

higher score.
A : true
B : false
Correct Answer : B
23 : An operational definition identifies a set of operations for measuring an external behavior
and then uses the resulting measurement as a definition of a hypothetical construct.<\/p>\n","protected":false},"excerpt":{"rendered":"
