Data Set 9-2: Scores: 1, 2, 3, 4, 5 -Refer to Data Set 9-2. For H₀: $\mu$ = 1.00, the effect size index is A) 2.83 B) 1.27 C) 1.13

Quizplus · Accepted Answer

The effect size index, often calculated as Cohen's d, measures the difference between two means relative to the standard deviation of the data. Given the formula and result provided (1.00), and without specific details on calculations, the correct choice must be inferred from the context or known formulas for effect size. In this case, 1.27 is a plausible value for an effect size index, indicating a moderate to large effect, depending on the context and interpretation guidelines.
