The following data are from an independent-measures experiment comparing two treatment conditions. Treatment 1: 1, 2, 3, 4, 5 Treatment 2: 6, 10, 12, 14, 18
Do these data indicate a significant difference between the treatments at the 0.01 level of significance
df = Pooled var. = Standard error = t = Reject null ("yes" or "no")?
For an independent-measures research study, the data show an 8-point difference between the two treatment means and a pooled variance of 4. Given this information, what is the value of Cohen’s d?
