What is Inter-Item reliability? What is the statistical measure that is often used to measure it?
What will be an ideal response?
When researchers use multiple items to measure a single concept, they are concerned with inter-item reliability (or internal consistency). For example, if we are to have confidence that a set of questions reliably measures an attitude, say, attitudes toward violence, then the answers to the questions should be highly associated with one another. The stronger the association between the individual items and the more items included, the higher the reliability of the index. Cronbach’s alpha is a reliability measure commonly used to measure inter-item reliability. Of course, inter-item reliability cannot be computed if only one question is used to measure a concept. For this reason, it is much better to use a multi-item index to measure an important concept (Viswanathan, 2005).
Test-retest reliability is a measurement showing that measures of a phenomenon at two points in time are highly correlated, if the phenomenon has not changed, or have changed only as much as the phenomenon itself.
Interitem reliability is an approach that calculates reliability based on the correlation among multiple items used to measure a single concept.
Cronbach’s alpha is a statistic that measures the reliability of items in an index or scale.
