A researcher reports that the mean difference in response time to an auditory versus a visual cue is 0.83 seconds, with a pooled sample variance equal to 2.45. What is the effect size for this test using estimated Cohen's d? d = 0.53; medium effect sized d= 0.53; large effect size d = 0.34; small effect sized d = 0.34; medium effect size

Step 1
83 / sqrt(2.45) Cohen's d ≈ 0.53 Now, we need to determine the effect size based on Cohen's d value: Show more…

A researcher selects a sample of n = 4 individuals from a normal population with a mean of μ = 70 and a standard deviation of σ = 4. A treatment is administered to the individuals in the sample. After treatment, the sample mean is M = 76. Using Cohen's d to measure effect size, what is the size of the treatment effect?

A researcher reports that the mean difference in the body weight of rats following a pharmacological versus control treatment is 14 g, with a pooled sample variance equal to 256. What is the effect size for this test using estimated Cohen's d? Group of answer choices a. d = 0.06; small effect size b. d = 0.08; small effect size c. d = 0.88; large effect size d. There is not enough information to answer this question.
In a completed study, there is a known population with a normal distribution, μ=25 and σ=12. What is the estimated effect size if a sample given an experimental procedure has a mean of (a) 19, (b) 22, (c) 25, (d) 30, and (e) 35? For each part, also indicate whether the effect is approximately small, medium or large.
