Validity Inference

Definition

Hypotheses

Analyses

Scoring

The scores from the scales adequately capture students’ perceptions of the psychological construct

H1: The mean values and standard deviations on the scales of the 19-item inventory will be similar to the values on the scales of the 26-item inventory

H2: Scales in the same inventory will demonstrate evidence of coherence and independence (i.e., the scales will not be highly correlated)

A1: Computing means and standard deviations for the scales in the 19- and 26-item inventories

A2.1: Computing Pearson’s correlation coefficients to assess associations between scales in the 19-item inventory

A2.2: Conducting factor analysis for all items in the 19- and 26-item inventories

Generalization

The items are representative of all theoretically possible items relevant to the construct

H3: The scale scores for the 19-item inventory will be highly correlated with scale scores for the 26-item inventory

H4: Internal consistency analysis will indicate low error variance for each scale (i.e., Cronbach’s alpha and McDonald’s omega values will be acceptable)

A3: Computing Pearson’s correlation coefficients to assess associations between the 19- and 26-item inventory scales

A4: Calculating Cronbach’s alpha and McDonald’s omega values for each scale

Extrapolation

The scores from the scales are related to other variables as anticipated

H5: Each scale score will be related to other variables as anticipated

A5: Computing Pearson’s correlation coefficients to assess associations between the scales and student effort, instructor ratings, and course ratings

  1. Notes. References to the “scales” refer to the five scales of the MUSIC Inventory: Empowerment, Usefulness, Success, Interest, and Caring. Each hypothesis number aligns with the analysis with the same number.
