Question
Indicate whether the statement is true or false. 1. If two samples each have the same mean, the same number of scores, and are selected from the same population, then they will also have identical t statistics. As the sample size is increased, the distribution of t statistics becomes flatter and more spread out. The results from an independent-measures t hypothesis test are reported as "t(14) = 2.13, p > .05, two tailed." For this test, the null hypothesis was rejected. For a repeated-measures design, df = n_1 + n_2 = 2 for the t statistic In an analysis of variance, MS_total = MS_between + MS_within. A repeated-measures study compares three treatments with a sample of n = 12 subjects. For the analysis of variance, df_error = 33 In a two-factor ANOVA, MS_between treatments = MS_A + MS_B + MS_A times B For a two-factor analysis of variance, the significance any specific ratio is completely independent of the significance of the other F-ratios. A chi square test for independence produces a chi-square with df = 2, The data for this research study form a matrix with four statistic separate categories.Explanation / Answer
Solution1:
true as
t=score-mean/sd
scores are same
mean and sd of normal distr will be same for a given population
Solution2:
true
as sample size increases
standard eroor decreases and t will be fallter
Solution3:
t cal for 14 df=2.13
p>0.05
so null hypothesis is not rejected according to decision rule
null hypothesis accepted
False
Solution4:
False
Solutio5:
True
MSbetewwn+MSeror=MStotal
