Question

A movie complex has eight different movie theaters. The manager of the complex wants to conduct a survey to determine which snacks to add on the menu. Which represents the best sample the manager could use for the survey?

A. Siri read the first 100 movie goers leaving the movie complex
B. Survey 100 randomly selected movie goers that just watched a drama movie.
C. Survey 100 randomly selected moviegoers in the 10 year old to 40 year old age bracket.
D. Survey 100 randomly select moviegoers from the entire complex.

Answer 1

B. Survey 100 randomly selected movie goers that just watched a drama movie. This sample is more specific and targeted than option A (which includes all movie goers, regardless of what movie they watched) and option D (which includes movie goers from all theaters and all types of movies). Option C could also work, but it may not be representative of the entire population that visits the movie complex, as it excludes those outside of the 10-40 age range. By selecting a specific movie genre, the manager can ensure that the sample is more homogenous and likely to have similar preferences for snacks.
