PRACTICE TEST 2026/2027
In general, the greater the between group variance compared to the within group variance, the more
likely you are to:
find statistical significance
support the null hypothesis
conclude that your sample was too small
reject the research hypothesis - ANS ✔✔find statistical significance
In one-way analysis of variance, the independent variable (also called the factor or grouping variable)
can be measured at the:
any level
nominal level
interval level
ratio level - ANS ✔✔nominal level
In a one-way ANOVA, which of the following are true: - ANS ✔✔It is conducted to analyze a dependent
variable that is measured at the interval or ratio level
Its outcome is a numerical value for the F statistic
Is similar to the t-test because the null hypothesis (no differences between groups) is rejected when the
analysis yields a smaller p value (e.g., <.05)
Although the ANOVA is a very robust test, when the assumptions for the test are seriously violated, you
should consider running: - ANS ✔✔Kruskall-Wallis Test
The t-Test is superior to the ANOVA when conducting multiple comparisons. - ANS ✔✔false
Researcher LeBlanc was interested in oncology nurses' attitudes toward palliative care with four age
groups of patients who all had cancer: pediatric (<15), adolescent or young adult (15-39), middle age
(40-64), and elderly (>64). After gathering data, she ran a one-way ANOVA. The F value was 22.4 and the
p value was 0.005. In interpreting her findings, she should: - ANS ✔✔run a post-hoc test (Scheffe or
Tukey) to see which groups differed
Which of the following is NOT an assumption for the ANOVA? - ANS ✔✔The groups can not be mutually
exclusive.
The ANOVA examines variance to determine if the group means differ. - ANS ✔✔true
The null hypothesis in one-way analysis of variance is: - ANS ✔✔any difference in group means comes
from a sampling error
