Question
1.
t tests are used to test the significance of the difference
test the significance
while a one-way ANOVA is used to
Between two means; among three or more means
b. Among three or more means; among at least three means
Between two independent variables; between dependent variables
d. Between two means; between two independent variables.
a.
с.
2. In order for a computed value of F to be significant, it must be
the critical value.
a.
Less than
b. Greater than
c. Equal to
d. Either b or c is true
3. In an analysis of variance of 42 people from three cities, the MSbg was 15, and the SSwg was 78. What was
the value of F?
a. 0.19
b. 7.50
c. 8.08
d. 5.20
4. Suppose you read a research study that concludes by saying, "A one-way ANOVA revealed that the three
group significantly differed, F (2, 49) = 4.00, p<0.05" What was the number of participants in the study?
a. 52
b. 51
c. 49
d. It is impossible to determine from the above information.
5. If the research hypothesis is true, we expect the mean square
to be larger than the mean square
a. Subgroups; between groups
b. Between groups; subgroups
Within groups; between groups
d. Between groups; within groups
с.
6. In an ANOVA, a post hoc test is
Done when the null hypothesis is rejected.
b. Done before the computed F is compared to the critical value of F.
Done when the researcher fails to reject the null.
d. Is always done when there are three or more groups.
a.
