TEST DEVELOPMENT

 Indication of the internal consistency of the scale.

• Item-Difficulty Index

• Item Reliability Index

• Item-Validity Index

• Item-Discrimination Index

Indicates how adequately an item separates between high scorers and low scorers on an entire test.

• Item-Difficulty Index

• Item Reliability Index

• Item-Validity Index

• Item-Discrimination Index

The proportion of respondents answering an item correctly that theoretically range from 0 (if no one got the item right) to 1 (if everyone got the item right).

• Item-Difficulty Index

• Item Reliability Index

• Item-Validity Index

• Item-Discrimination Index

A statistic designed to provide an indication of the degree to which a test is measuring what it claims to measure.

• Item-Difficulty Index

• Item Reliability Index

• Item-Validity Index

• Item-Discrimination Index

Responses earn credit toward placement in a particular class with other test takers whose pattern of responses is presumably similar in some way (e.g diagnostic testing).

• Computerized adaptive testing (CAT)

• Cumulatively scored test

• Class scoring

• Ipsative scoring

Each item presents the testtaker with five alternative responses (sometimes seven), usually on an agree-disagree or approve-disapprove continuum.

• Likert scale

• Method of Paired Comparisons

• Guttman scale

• Scalogram Analysis

He was very influential in the development of sound scaling methods.

• Spearman

• Thurstone

• Pearson

• Cronbach

A relatively large and easily accessible collection of test questions.

• Item Bank

• Item Pool

• Item Analysis

• Item Range

This format has three elements: (1) a stem, (2) a correct alternative or option, and (3) several incorrect alternatives or options variously referred to as distractors or foils.

• Completion-Item Format

• Constructed-Response Format

• Selected-Response Format

• Multiple-choice format

Among the tools test developers might employ to analyse and select items are the following, EXCEPT THE TWO:

• an index of the item's difficulty

• an index of item discrimination

• an index of item precision

• an index of item format
