q3 i? A regression model with the efficiency measures accounted for 28.3% of variance in performance success, with exploratory experiments negatively related to success. → Ard W. Lazonder 2009 q3 i? In a stepwise regression, exploratory experiments was the only parameter with a significant impact on performance success. → Ard W. Lazonder 2009 (2)

q3 · i? · causal · r2

Multiple regression on the experiment's data (N = 56) predicting performance success from efficiency measures. Exploratory experiments carried a negative unstandardized coefficient (-.047), and hypothesis percentages positive coefficients (.078, .055, .073); R² values are variance explained, not effect sizes.

"Using the Enter method, a significant model emerged ( F(7,48) = 4.10, MSE = 5.85, p\ .01) that accounted for 28.3% of the variance in performance success."

q3 · i? · causal · r2

Stepwise regression on the same data confirmed that the percentage of exploratory experiments was the only significant predictor, with the article reporting "Adjusted R2 = .223, b =- .487, p\ .001"; the article concludes that mere testing of hypotheses, regardless of specificity, was the strongest predictor.

"exploratory experiments was the only parameter in the model that had a significant impact on performance success scores (Adjusted R2 = .223, b =- .487, p\ .001)."
