In Sprowl's method, the E value is fixed at what value?

• A. 0.2
• B. 0.3
• C. 0.4
• D. 0.5

Answer: (B)

In Sprowl's method, E is treated as a fixed constant rather than something estimated from the data. This makes the procedure straightforward and comparable across problems. The value is set at 0.3 because it provides a practical balance between sensitivity to true signals and robustness against random variation. If E were smaller, the method could overreact to outliers; if larger, it could smooth away real differences. The historical choice of 0.3 has proven to work well across typical scenarios, so the E value is fixed at 0.3.
