The most popular unidimensional psychological test evaluation rule is the trivial scoring function: To the answers of each item of a test item scores of 0,1,...m points are awarded and the unweighted or simple or total sum of the item scores gives the test score (also: Likert score). This total score has desirable stochastic ordering properties like monotone likelihood ratio (MLR), stochastic ordering of the sum score by the latent dimension (SOM) and stochastic ordering of the latent dimension… CONTINUE READING
