Operator-System Interaction

Whether operator performance varies by system (model/tool/platform). Tests for interaction effects.

Metric profiles for operators across multiple systems.

Interaction effect size, main effects for operator and system.

If operator-system interaction exists, the same operator will perform differently on different systems, and different operators will rank differently on different systems.

Two-way ANOVA (operator × system) on metrics. Test for significant interaction effects.

Interaction F-ratio, p-value, simple main effects.

No significant interaction effect (operator ranking is identical across all systems).

Field data suggests interaction effects exist. Formal analysis not yet conducted.

Confounded by task selection — operators may choose different tasks on different systems.
