Randomization test of hypothesized order relations

The randomization test of hypothesized order relations (RTHOR; Hubert & Arabie (1987)) is commonly used with assessments based on the RIASEC model. The RTHORR package (Tracey & Morris (2021)) computes a consistency index and associated p-value to determine if the pattern of correlations observed matches what we would expect.

For RTHOR results for respondents residing in Philippines, see the table below.

Gender differences

Gender differences on vocational interests have been found consistently for decades, and exist across various interest inventories, including the Strong assessment (Morris (2016); Su et al. (2009)).

PSSs

Reliability

Because of the different construction methods of different PSSs, internal consistency is meaningful for only two of the six PSSs: Risk Taking and Team Orientation. These are the two PSSs that were developed from homogeneous item content. Test-retest reliability is not available for this country.
