MODULE #5

Question 1

refers to the accuracy and precision of research tool. When a measure is precise, then the reader has a level of confidence that differences between groups are not explained by differences in the way the trait was measure

Answer 1

RELIABILITY

Question 2

Methods of testing reliability

Answer 2

a. Stability of measurement
b. Internal Consistency
C. Equivalence

Question 3

this is the extent to which the scores are obtained when the instrument is used with the same samples on separate occasions. A stable research instrument is one that can be repeated over and over on the same research subject and will produce the same result

Answer 3

Stability of measurement

Question 4

Test of stability

Answer 4

Test - Retest
Repeated observations

Question 5

the repeated measurements over time using the same instrument on the same subjects is expected to produce the same results. This is used in interviews, examinations, and questionnaires.

Answer 5

Test - Retest

Question 6

The measurement of the variable or trait is repeated over time, and the results at each measurements time are expected to be similar

Answer 6

Repeated observations

Question 7

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

Answer 7

Internal Consistency

Question 8

Tests of internal Consistency

Answer 8

Split-Half Correlations
Cronbach’s alpha coefficient

Question 9

Tests of internal Consistency

Answer 9

Split-Half Correlations
Cronbach’s alpha coefficient

Question 10

scores on one half of a subject’s responses are compared to scores on the other half, if all items are consistently measuring the overall concept, then the scores on the two halves of the test should be highly correlated

Answer 10

Split-Half Correlations

Question 11

a measure of internal consistency, that is, how closely related a set of items are as a group. It is useful device for establishing reliability in a highly structured quantitative data collection instrument.

Answer 11

Cronbach’s alpha coefficient

Question 12

primarily concerns the degree to which two or more independent observers or coders agree about scoring. If there is a high level of agreement, then the assumption is that measurement errors have been minimized

Answer 12

Equivalence

Question 13

Tests of Equivalence

Answer 13

1. Alternate Form
2. Inter Rater

Question 14

two tests are developed based on the same content but the individual items are different. When these two tests are administered to subjects at the same time, the results can be compared

Answer 14

Alternate form

Question 15

this is the method of testing for equivalence when the design calls for observation
and is used to determine whether two observes using the same instrument at the same time will obtain similar results

Answer 15

Inter-Rater

Question 16

is a measure of consistency an observer is at messuring a constant phenomenon

Answer 16

Inter-Rater Reliability

Question 17

is a measure of consistency an observer is at messuring a constant phenomenon

Answer 17

Inter-Rater Reliability
