Reliability and Item Analysis

In many areas of research, the precise measurement of hypothesized processes or variables poses a challenge by itself. Reliability and Item Analysis can be used to construct reliable measurement scales to improve existing scales and to evaluate the reliability of scales already in use.

Note: Learn more about the object model by reading Statistica user documentation. The Statistica application's user interface and object model have similar options. The documentation contains overviews of the analytics, descriptions of the input and outputs for the analyses, and step-by-step examples.
