Answer to Question 1

B
A frequency distribution that lists all the responses made by 500 respondents would be unwieldy and too long to be able to summarize the responses effectively. For large data sets, the mean gives, in a single number, a summary of how all the participants responded.

Answer to Question 2

C
Counts and frequencies would reflect the number of times any category (type of movie) was chosen by an individual as her first choice. Respondents are the people who respond to the questions asked by the researcher.
