A company wants to research the effectiveness of different types of marketing on consumer perspective. The company leadership is comprised of mostly Christians. In a meeting, they were discussing to what extent they should "let their good works be seen of men" (Matthew 5:16) versus Matthew 6:1 which says "do not practice your righteousness in front of others to be seen of them". You have been hired to evaluate the company's efforts, and perhaps direct their future marketing efforts. Specifically, they are wondering whether advertising efforts emphasizing the company's community service and philanthropic efforts can be under or over saturated in regards to how consumers view the company. To assess this, you have been tasked to research the consumer rating on this issue. Therefore, you have designed a study where you will target one group of consumers with low philanthropic advertising, another group with high philanthropic advertising, and a placebo group which will be shown the same number of company advertising but without the philanthropic focus. Data collection will involve a measure to collect the ratings of likelihood to purchase from this company by the participants/potential customers. They have agreed to pay the expenses to have a group of participants come to a neutral location to watch advertisements for several hours in one day. Because travel and food cost have increased, and because they are paying you such a great.

Which nonparametric measure(s) would you use in this study, and why? Be sure to clearly connect and explain how your design accurately fits the characteristics of the statistic, or statistics, that you select.
