SAS3f: SAS3f database

In unival: Assessing Essential Unidimensionality Using External Validity Information

Description

A database to be used as example in the functions included on unival package. It contains the criterion, the primary factor scores and the general factor scores obtained using the program FACTOR. Those scores were obtained used a dataset of 238 responders to the Statistical Anxiety Scale (Vigil-Colet, Lorenzo-Seva, & Condon, 2008). For clarification: it does not contain the raw scores from the participant's answers to the test.

Usage

data("SAS3f")

Format

A data frame with 238 observations and 5 variables, corresponding to the criterion, the primary factor scores and the general factor score.

Details

The original test contains 24 items and measures 3 different anxiety subscales: Examination Anxiety , Asking for Help Anxiety and Interpretation Anxiety. Since they are highly correlated, they were considered related subscales from an overall scale, which measures statistical anxiety.

Since the package unival was designed for working with the factor scores and not the raw data, the provided datasets include the factor scores instead the raw data. It also contains a criterion, which in this case are the marks obtained by the responders on an Statistical exam.
