When Grace was analyzing the findings from a recent survey conducted by her firm, she wanted to understand if there was a difference between age cohorts and their level of brand loyalty. She decided to separate the responses to the question on loyalty (low, moderate or high) and by age groups (18-30, 31-45, 46-60, and 61+) to test her theory that younger age groups were more loyal to the company's brand than older consumers. She will prepare a _____________, fill in the blank, to gain this insight and illustrate the findings.

a)Measure of dispersion

b)Focus group

c)Test market

d)One way frequency distribution
