STATS MODULE 5 QUIZ TEST WITH
CORRECT ANSWERS
The cutoff F used to evaluate the significance of the Scheffé
test for any particular comparison between two group means is
- CORRECT ANSWER-the same cutoff F used for the overall
study.
in an analysis of variance with a within-groups variance
estimate of 8.5 and a between-groups variance estimate of 5.3,
the F ratio is - CORRECT ANSWER-5..5 = 0.62
In an analysis of variance, if the null hypothesis is false, then -
CORRECT ANSWER-the variation between sample means
reflects the variation within the populations as well as the
variation between the population means.
In an analysis of variance, if the null hypothesis is true, then -
CORRECT ANSWER-there is less variance among means of
samples than if the null hypothesis were not true.
the within-groups estimate of the population variance is smaller
than the between-groups estimate.
An analysis of variance differs from a t test for independent
means in that an analysis of variance - CORRECT ANSWER-
can be used to compare three or more groups, while a t test for
independent means cannot be used to compare more than two
groups.
The formula "Σ( M- GM) 2/ df Between" is used to compute -
CORRECT ANSWER-the between-groups estimate of the
population variance.
, If a research article does not report the variance estimates, R 2
- CORRECT ANSWER-can be figured by [( F)( df Between)]/[(
F)( df Between) + df Within].
If a research article reports " F (2, 36) = 2.95, p < .05," you
know that - CORRECT ANSWER-there were 39 participants.
When sample sizes are equal, MS Within is figured by -
CORRECT ANSWER-summing the population variance
estimates figured within each group and dividing this sum by
the number of groups
the correct order of post hoc comparison procedures following
an analysis of variance from the least conservative to the most
conservative is - CORRECT ANSWER-Tukey, Scheffé,
Bonferroni
What is the relationship between the amount of time spent
shopping, Short (under 15 minutes) or Long (over 15 minutes),
and the age of the shopper, Young (under 22) or Old (over 22),
and the amount of money spent by shoppers in a music store.
A store manager said, "How much money people spend isn't
related to age. All that matters is how long they shop." If she
said that after seeing the results of one of these studies, which
scenario was she probably looking at? - CORRECT ANSWER-
none of the above
A consumer psychologist is interested in the effects of Annual
Income and Motivations to Shop on shopping patterns of
consumers. If Annual Income is divided into two levels (High
and Moderate) and Motivation to Shop is divided into three
levels (Escape, Necessity, and Socializing), and both are
considered in one study, the number of cells will be -
CORRECT ANSWER-6
