Question

Macy wanted to know what color themes are currently most popular for spring dresses. She specifically wanted to compare A) yellow-pink floral, B) red-purple wave, and C) white-baby blue mess dress styles. She took pictures of a model wearing each dress type, and then asked 400 young women to rate how much they liked each dress style picture. What statistical test should Richard use of analyze this data?

1. independent-measures t-test
2. repeated-measures t-test (paired-sample t-test)
3. independent-measures ANOVA
4. repeated-measures ANOVA

Answer 1

The correct answer is Option 4. Repeated measures ANOVA should be used, since we are comparing more than two categories of data. Furthermore, the same participant is being exposed to all the categories.
