Question
All of the following are assumptions of the repeated measures t-test EXCEPT a. the two populations that were sampled from have unequal variances (heterogeneity) b. the population that was sampled from is normal c. observations within each treatment condition are independent d. both answers b and c Which of the following are advantages of repeated measures t-tests over independent measures t-tests a. more subjects are needed for equivalent degrees of statistical power b. the influence of individual differences on treatment effects are better controlled for c. treatment effects that occur over time are more easily studied d. both answers band c A researcher runs three separate t-tests in order to evaluate a single hypothesis concerning three doses of experimental drug. The researcher sets the alpha-level of each t-test at 0.05. In this scenario, is the te wise alpha-level and ________ is the experiment-wise alpha-level. a. 0.20: 0.60 b. 0.01: 0.03 c. 0.05: 0.15 d. 0.15: 0.45 All of the following are assumptions of the independent measures ANOVA EXCEPT: a. observations within and between each treatment condition are independent b. the populations that were sampled from are normal c. heterogeneity of variance populations exists (variances are significantly different) d homogeneity of variance between populations exists (variances are not significantly different) Bubble in the corresponding letter for the terms most closely matched with respect specifically to ANOVAS. Number of groups/treatments ANOVA term for variance Single Independent Variable ANOVA term for Independent Variable a. mean squared deviation (MS) b. factor c. one-way ANOVA d. levels of a factor The test statistic for an ANOVA is actually a ratio of values and is noted by (F). In independent- measure ANOVAs, ___________ comprises the numerator of this ratio, whereas ___________ comprises the denominator of ratio. a. MS_ statements: MS_ Investments b. variance _: covariance_ treatments c. variance_ treatments: variance_ within treatments d. both answers a and b What does the term ANOVA stand for? a. automated notation of variance b. analysis of variables c. analysis of covariance d analysis of varianceExplanation / Answer
