Usage

data("test.data")

Format

The format is: A list with 4 objects:

$ Algebra :'data.frame': 150 obs. of 15 variables:

$ Measurement:'data.frame': 150 obs. of 20 variables:

$ Math :'data.frame': 150 obs. of 50 variables:

Details

Algebra: Responses of 150 participants to 15 items; Geometry: Responses of 150 participants to 15 items. Measurement: Responses of 150 participants to 20 items; Math: Responses of 150 participants to 20 items.
