WebDec 22, 2024 · Revised on November 17, 2024. Effect size tells you how meaningful the relationship between variables or the difference between groups is. It indicates the practical significance of a research outcome. A large effect size means that a research finding has practical significance, while a small effect size indicates limited practical applications. WebWhich combination of factors is most likely to produce a significant value for an independent-measures t statistic? (chapter 10) A large mean difference and small sample variance. T/F: If both samples have n = 10, the independent-measures t statistic will have df = 19 (chapter 10) False - df = 18.
