Question

determine whether the following sampling method is dependent or independent. indicate whether the response variable is qualitative or quantitative
a researcher wishes to compare preferred soda flavors of pharmacists and non - pharmacists. she obtains a random sample of 320 professionals of each category who drink soda and determines each individuals preferred soda flavor

determine whether the sampling method is dependent or independent.
a. the sampling is dependent because an individual selected for one sample dictates which individual is to be in the second sample.
b. the sampling is independent because an individual selected for one sample does not dictate which individual is to be in the second sample.
c. the sampling is independent because an individual selected for one sample dictates which individual is to be in the second sample.
d. the sampling is dependent because an individual selected for one sample does not dictate which individual is to be in the second sample.

Explanation:

Independent sampling means that the selection of individuals in one sample has no influence on the selection of individuals in the other sample. Here, selecting a pharmacist (or non - pharmacist) for the first sample does not affect which non - pharmacist (or pharmacist) is selected for the second sample. Qualitative variables describe characteristics or categories. Preferred soda flavor is a category (e.g., cola, lemon - lime, etc.), so it is qualitative.

Answer:

For the sampling method: B. The sampling is independent because an individual selected for one sample does not dictate which individual is to be in the second sample.
For the response variable: Qualitative.
