q3 i? Median switch score was significantly lower in the Inefficient first condition than the Efficient first condition. → Davis 2022

Evidence¶

Davis 2022¶

q3 · i? · causal · r2

Comparing conditions with nonparametric tests, "the median switch score in the Inefficient first condition (Med = 4.00), was significantly lower than that of the Efficient first condition (Med = 7.00, Z = − 11.74, p < 0.001)". The proportion switching did not significantly differ between conditions.

"the median switch score in the Inefficient first condition (Med = 4.00), was significantly lower than that of the Efficient first condition (Med = 7.00, Z = − 11.74, p < 0.001)"
