Total scores reported = Yes

Elements with extreme scores (zero, perfect) do not provide information about the measures of other elements and so are dropped from the estimation. Estimates for extreme scores are done separately with Xtreme score=.

 

Totalscore = No (default)

Report scores after omission of responses that are part of extreme scores

Totalscore = Yes

Report scores including all responses.

 

Example: For the KCT data.

Totalscore = No omits observations in other extreme scores. It produces:
