Module 5

Question 1

Refers to the accuracy and precision of research tool

Answer 1

Reliability

Question 2

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

Answer 2

Stability of the measurement

Question 3

A ‘one that can be repeated over and over’ (at different times) on the same subject research

Answer 3

Stable research instrument

Question 4

Define the type of concept: intelligence

Answer 4

stable concept

Question 5

Define the type of concept: pain

Answer 5

unstable concept

Question 6

Define the type of concept:
it can be ‘measured repeatedly’, at regular intervals, and to ‘obtain the same score’

Answer 6

stable concept

Question 7

Define the type of concept: changeable

Answer 7

unstable concept

Question 8

The ‘repeated measurements over time using the same instrument’ on the research subjects

Answer 8

test-retest

Question 9

This test of stability is used in interviews, examinations, and observations

Answer 9

test-retest

Question 10

This method has the same basic elements as test/retest

Answer 10

repeated observations

Question 11

This instrument shows that ‘all indicators or sub parts measures the same characteristics or attributes of the same variables’

Answer 11

internal consistency

Question 12

What are the test of stability?

Answer 12

test-retest
repeated observation

Question 13

What are the test of the internal consistency?

Answer 13

split half correlation
cronbach’s alpha coefficient

Question 14

scores on one half of a subjects responses are compared to scores on the other half

Answer 14

split half correlation

Question 15

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

Answer 15

cronbach’s alpha coefficient

Question 16

concerns to the degree to which ‘two or more independent observers or coders agree about scoring’

Answer 16

equivalence

Question 17

Two types of equivalence:

Answer 17

alternative form
inter-rater/intra-rater reliability

Question 18

when 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 reliablity

Question 19

two tests are developed based on the same content

Answer 19

alternative form
