lesson 5

Question 1

refers to the accuracy and precision of the tool

Answer 1

reliability

Question 2

The scores are obtained when the ‘instrument is used with samples on separate occasions’

Answer 2

stability of the instrument

Question 3

The one that can be repeated over and over (at different times)

Answer 3

stable research instrument

Question 4

It can only be done when you assume that ‘the trait being measured will remain constant over time’

Answer 4

Major limitation

Question 5

Example of stable concept

Answer 5

Intelligence

Question 6

Example of stable concept

Answer 6

Intelligence

Question 7

Example of unstable concept

Answer 7

Pain

Question 8

The repeated measurements over time using the same instrument on the same subject

Answer 8

Test-Retest

Question 9

This type of stability is used in interviews, examination, and questionnaires

Answer 9

Test-Retest

Question 10

This method has the same basic elements as test/retest

Answer 10

Repeated Observations

Question 11

The instrument shows that “all indicators or subparts measure” the same characteristics or attributes of the variables

Answer 11

Internal Consistency

Question 12

What are the test of stability

Answer 12

Test-Retest
Repeated Observations

Question 13

Scores on one half of a subject’s responses are compared to scored on the other half

Answer 13

Split half correlation

Question 14

A measure of internal consistency, that is “how closely related a set of items are as a group”

Answer 14

Cronbachs Alpha Coefficient

Question 15

Types of Internal Consistency

Answer 15

Split half correlation
Cronbachs Alpha Coefficient

Question 16

Primarily concerns the degree to which “two or more independent observers or coders agree about scoring”

Answer 16

Equivalence

Question 17

Two test are developed based on the same content but the ‘individual items are different’

Answer 17

Alternate form

Question 18

The ‘design calls for observation’ and is used to determine whether two observers using the same instrument at the same time will obtain similar results

Answer 18

Inter-Rater/Intra-Rater Observation

Question 19

A measure of consistency an observer is at measuring a constant phenomenon

Answer 19

Intra-rater reliability
