Title: For a chi-square test, the observed frequencies are obtained from the sample. (True or false?) Post by: Arroyo21 on Mar 19, 2018 For a chi-square test, the observed frequencies are obtained from the sample.
Indicate whether the statement is true or false Question 2 If other factors are held constant, how does sample size influence the likelihood of rejecting the null hypothesis and measures of effect size such as r2 and Cohen's d? A) A larger sample increases both the likelihood and measures of effect size. B) A larger sample increases the likelihood but has little influence on measures of effect size. C) A larger sample decreases the likelihood but has little influence on measures of effect size. D) A larger sample decreases both the likelihood and measures of effect size. Question 3 For a chi-square test, the expected frequencies are calculated values that are intended to produce a sample that is representative of the null hypothesis. Indicate whether the statement is true or false Question 4 A sample of n = 16 scores produces a t statistic of t = 2.00. If the sample is used to measure effect size with r2, what value will be obtained for r2? A) r2 = 2/20 B) r2 = 4/20 C) r2 = 2/19 D) r2 = 4/19 Title: For a chi-square test, the observed frequencies are obtained from the sample. (True or false?)
