To examine the impact of three different types of wall paint colors (blue,green,and yellow) on how often toddlers cry,which test is appropriate to use?

A) factorial ANOVA
B) t-test for dependent samples
C) t-test for independent samples
D) one-way ANOVA

A one-way ANOVA is appropriate when comparing the means of more than two groups. In this case, there are three groups (blue, green, and yellow), so a one-way ANOVA is the best choice. A factorial ANOVA would be used if there were multiple factors being tested (such as wall paint color and lighting), a t-test for dependent samples would be used if the same group of toddlers was tested under different conditions (such as crying levels with and without the presence of a parent), and a t-test for independent samples would be used if two separate groups of toddlers were being compared (such as crying levels in toddlers who attend daycare versus those who stay at home).
