Question 1
2 / 2 pts
If the null hypothesis is rejected in a one-way ANOVA with three groups, then we can
infer that:
there is a significant difference among all the means for each of the three possible
pairings.
there is no significant difference in means for each of the three possible pairings.
there is probably at least one significant difference in means among the three possible
pairings.
Question 2
2 / 2 pts
Why would a researcher choose to conduct an One-Way ANOVA rather than multiple
independent samples t-tests?
to detect significant differences between groups on some outcome variable Y.
to complete a more complex analysis.
because multiple pairing of -tests with more than two groups will inflate Type I error. t
The ANOVA omibus test considers the differences simultaneously thereby controlling F
for Type I error.
