Experiment 1. This is a by-items dataset with the following variables:

ProbNum: Problem number

CHratio: Convex hull ratio of the arrays

Dotratio: Cumulative dot area ratio of the arrays

Numratio: Numerical ratio of the arrays

MeanAge: Year group mean age

Accuracy: Mean accuracy

Experiment 2. This is a by-items dataset with the following variables:

ProbNum: Problem number

CHratio: Convex hull ratio of the arrays

Dotratio: Cumulative dot area ratio of the arrays

Numratio: Numerical ratio of the arrays

Timing: Display time in ms

Accuracy: Mean accuracy
