Looking at the experimental data below, I want to expand on my experiment to test whether there is a difference in preference based on the age of the participant. Which experimental design below will accomplish this? Type of cereal on the X axis, Number of votes on the Y-axis Question 3 options: Run a new test with all participants over the age of 30 testing the different types of cereals. Run a new test with all new brands of cereal, introducing new types of cereal that typically appeal to younger ages, such as Fruit Loops and Captain Crunch. Run a new test with participant groups separated by age- one group will contain participants below the age of 18. The other group will contain participants over the age of 18. Run a new test with two groups of people separated by gender- one group will be composed of males of different ages and the other group will be made of females of different ages.
