Question

Answers are either;

-Always

-Sometimes

-Never

(5 points) Consider each of the statements below. For each statement, decide whether it is sometimes, always, or never a true statement.

1. A hypothesis test that produces a positive test statistic can produce a positive effect size. (Always, Sometimes Or Never)

2. In order to compute Cohen's ?d, a statistician must directly know the sample size. (Always, Sometimes Or Never)

3. If two identical studies on the same topic both produced estimated effect sizes less than ?̂=0.6d^=0.6, a third study that uses the same procedures will also produce an estimated effect size less than 0.60.6. (Always, Sometimes Or Never)

4. A hypothesis test that produces a ?p-value <0.001<0.001 will produce an effect size |?̂|>0.8|d^|>0.8 (Always, Sometimes Or Never)

5. In general, increasing the sample size in a statistical study will decrease the standard error of the statistic computed from the sample. (Always, Sometimes Or Never)
