zPSI R Documentation
Scale-Center-Standardized PSI Ratings
Description
Transforms ESJT ratings into a z-score-like metric indicating
the number of 'standard-deviations-from-zero' the person's original rating of the item was.
Usage
zPSI(PSIdata)
Arguments
PSIdata
original PSI data (should have 'p','s','i' for first three columns)
Details
This syntax implicitly assumes that 0 is a meaningful point on the scale.
The original data collection and the prior processing of the data should reflect this.
* The scale-centered scores do NOT have the usual interpretation of
[regular] z-scores as being translatable to approximate probabilities assuming
a normal distribution of responses.
* If the person gives the same score to all items, all zcx
will equal 1.
Value
Standardized scale-centered scores.
Original matrix but with data now equating level of variability for each participant
