What is meant by internal consistency?
Definition. Internal consistency reflects the extent to which items within an instrument measure various aspects of the same characteristic or construct.
What is an example of internal consistency?
For example, if a respondent expressed agreement with the statements "I like to ride bicycles" and "I've enjoyed riding bicycles in the past", and disagreement with the statement "I hate bicycles", this would be indicative of good internal consistency of the test.
What is the difference between internal consistency and validity?
The degree to which an instrument reflects what it is proposed to measure is reflected in validity. Internal consistency is a form of reliability. This property is most relevant to performance measures that consist of multiple items that are to be summarized clinically into a composite score.
What are the 3 types of internal reliability?
There are three types of internal consistency reliably: Cronbach's Alpha, Average Inter-Item, Split-Half Reliability and Kuder-Richardson test. Each of these options is a statistical measure that considers the data collected and results in a metamaterial correlation.
What determines internal consistency?
Internal consistency is typically measured using Cronbach's Alpha (α). Cronbach's Alpha ranges from 0 to 1, with higher values indicating greater internal consistency (and ultimately reliability).
