In a 1-Factor analysis of variance (ANOVA) for independent samples, three samples are randomly drawn from a population of hyperactive children. Children in each sample are treated at different drug dosage levels. During treatment, hyperactive behavior is observed. The average frequency of hyperactive behavior is calculated for each sample and sample means are compared.
a) Children in the popluation are assumed to be nontreated hyperactive children? True or false
b) under the null hypothesis (assuming H0 as states is true), the relationship between sample. means is represented in symbols as : A) a. mu1 ne mu2 ne mu3. OR mu 1 = mu 2 = mu 3
c) The observed statistic constructed as a direct test of the null hypothesis H0 is : a)tobs b tcritical c . F obs d. Fcritical
d) the numerator of the ratio of variances (mean squares; MS) in the construction of Fobs is : a) the average sum of squares between sample means ( MSbetween ) or. b. the average sum of squares within samples (MS within )
E) the numerator of the ratio of variances (Mean Squares; MS) in the construction of F obs is
a. the average sum of squares between sample means (MSbetween) OR b. the average sum of squares within samples (MSwithin )
F)if the null hypothesis (H 0 ) as stated is true, F obs is less than Fcritical. a . true b. false
G)if F obs is more extreme in its departure from zero than Fcritical, then which of the following two decisions about the null hypothesis (H a ) is appropriate? a. reject b . fail to reject
H)if the null hypothesis is rejected based on the single probability of occurrence of F obs (p<.05) , an alternative hypothesis can be considered stating that there is an a. inequality of sample means ( mu 1 ne mu 2 ne mu 3 ) b. equality of sample means ( mu 1 = mu 2 = mu 3 )
