Item-Explanatory Mokken Scaling: Using Nonparametric Item Response Theory to Explore Item Characteristics

• In Event: Nonparametric IRT

Abstract

We considered how nonparametric IRT techniques can be used to explore item characteristics. We used two real-data illustrations and evaluated the sensitivity of the approach using a simulation. Results suggested that MSA techniques can be extended to examine item properties for evidence of monotonicity and invariant ordering.
