Closed Ended (Fixed Choice) Questions |
Survey question providing preformulated response choices for the respondent to circle or check |
|
|
Concept |
A mental image that summarizes a set of similar observations, feelings, or ideas. |
|
|
Construct Validity |
The type of validity that is established by showing that a measure is related to other measures as specified in a theory. |
|
|
Content Validity |
The type of validity that establishes a measure covers the full range of the concept's meaning. |
|
|
Discriminant Validity |
An approach to construct validation; scores on the measure to be validated are compared to scores on another measure of the same variable and to scores on variables that measure different but related concepts. Discriminant validity is achieved if the measure to be validated is related most strongly to its comparison measure and less so to the measures of other concepts. |
|
|
Face Validity |
The type of validity that exists when an inspection of the items used to measure a concept suggests that they are appropriate "on their face." |
|
|
Interobserver Reliability |
When similar measurements are obtained by different observers rating the same persons, events, or places. |
|
|
Interval Level of Measurement |
A measurement of a variable in which the numbers indicating a variable's values represent fixed measurement units, but have no absolute, or fixed, zero point. |
|
|
Intraobserver reliability |
Consistency of ratings by an observer of an unchanging phenomenon at two or more points in time. |
|
|
Level of Measurement |
The complexity of the mathematical means that can be used to express the relationship between a variable's values. The nominal level of measurement, which is qualitative, has no mathematical interpretation; the quantitative levels of measurement (ordinal, interval, and ratio) are progressively more complex mathematically. |
|
|
Measurement Validity |
The type of validity that is achieved when a measure measures what it is presumed to measure. |
|
|
Reliability |
A measure is reliable when it yields consistent scores or observations of a given phenomenon on different occasions. Reliability is a prerequisite for measurement validity. |
|
|
Unobtrusive Measures |
Measures that allow researchers to collect data about individuals or groups without their direct knowledge or participation. |
