d. a and b only. - CORRECT ANSWER-b. a parametric test (Ordinal)
The Kruskal-Wallis test is used to determine whether the distributions of which of the following
are different from each other?
a. Two independent measures
b. Three or more independent measures
c. Repeated measures from a case and a matched control
d. Repeated measures from three or more groups - CORRECT ANSWER-b. Three or more
independent measures

is
a. nominal.
b. ordinal.

d. any of the above. - CORRECT ANSWER-c. interval or ratio
, The Kruskal-Wallis H-test can be used when
a. the total sample size is unknown.

the
a. within-group variance of the groups to each other.
b. within-group variance to the between-group variance.
c. ranks of the raw data.

variance to the between-group variance
The one-way ANOVA test tells you
a. whether the mean of one or more groups is different from the others.
b. which group mean is different from the others.
