CTT (version 2.3.3)

score: Function to score the response files

Description

This function can score multiple choice item responses. This function can also call and return results from function reliability.

Usage

score(items,key,output.scored=FALSE,ID=NA,rel=FALSE,multiKeySep="none",
         multiKeyScore=c("or","poly"))

Arguments

items

The item responses to be scored

key

The answer key

output.scored

If output.scored=FALSE (the default) only a vector of scores is returned. If output.scored=TRUE a matrix containing scored items is returned.

ID

If respondent IDs are provided scores are labeled appropriately.

rel

If rel=TRUE, the function will call the function reliability and provide that output as well.

multiKeySep

If a value other than "none" is provided (e.g., ","), the key and the raw items will be reviewed for the provided delimiter. Using this otion allows for multiple correct responses.

multiKeyScore

The first value controls how multiple keys are handled. If "or" any correct response results in score of 1. If "and" all responses must be correct. If the second value is "poly" the returned score is the sum of correct responses. If the second value is "dich" a maximum score of 1 is returned. If the respondent can only provide one response, use "or". If the responded can provide multiple responses and you use c("and", "poly") the score will be 0 or max score.
