Read the scenario to answer questions #2-4.

Imagine that marketing researchers working for a food company want to determine whether children would prefer ketchup of a different color. They develop green and blue to compare to their standard red (all taste the same). They have all children taste all three colors of ketchups and rate each on a scale of 1 - 10, with a higher number indicating better taste.

2) What is the Independent Variable? How many levels does it have? 

3) Is this a between-subjects or within-subjects design?

4) If the data violated many of the assumptions for a parametric test, what would be the most appropriate nonparametric statistical test? What would be the most appropriate graph? 

Can you check my answers please and help me if they're not right?

  1. the taste of the ketchup ; 3 levels
  2. within-subjects?
  3. boxplot?
