Question 4

How many parts of parallel forms reliability?

2 parts

How many parts of test-retest reliability?

2 parts

What is the relationship between Reliability to Validity?

3 key points of relationship

How many parts of internal consistency reliability?

3 parts

How many types of Reliability?

4 types

What is Reliability?

Consistency, Dependability, & Stable Data

What is interrater reliability estimates?

Raters have to agree & be reliable

What is the definition of Reliability?

The degree of consistency, dependability, & stability of scores on a measure used in selection research (either predictors or criteria)

What are the key points of the relationship?

1.) Validity of a measure depends on its reliability 2.) Reliability of predictor & criterion scores is necessary , but not sufficient for a score's validity 3.) You can have a reliable test, but it could not be valid!

What are the parts of test-retest reliability?

1.) assess the consistency of a measure from one time to another 2.) length of time is long enough to offset memory (lots of complex items/more than 8 weeks)

What are the parts of internal consistency reliability?

1.) assess the consistency of results across items within a test 2.) similarity of content (all parts are similar in what they measure) 3.) split half (one administration/split into halves)

What are the parts of parallel forms reliability?

1.) assess the consistency of the results of two tests constructed in the same way from the same content source 2.) coefficient of equivalency

How many measures of interrater reliability estimates?

1.) interrater agreement (% agreement and others) *most popular* 2.) interclass correlation (interval ratings scales) 3.) intraclass correlation (best for multiple raters = 3 or more)

What are the types of Reliability?

1.) test-retest reliability 2.) parallel forms reliability 3.) internal consistency reliability 4.) interrater reliability
