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. 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. indicate whether the response variable is qualitative or quantitative. a. the variable is quantitative because it classifies the individual. b. the variable is quantitative because it is a numerical measure. c. the variable is qualitative because it is a numerical measure. d. the variable is qualitative because it classifies the individual.

Explanation:

• For the sampling method:
• In independent sampling, the selection of one sample does not affect the selection of the other sample. Here, pharmacists and non - pharmacists are two separate groups, and choosing a pharmacist does not dictate which non - pharmacist is chosen.
• For the response variable (preferred soda flavor):
• Qualitative variables classify individuals into categories. Preferred soda flavor (e.g., cola, lemon - lime, etc.) is a category that classifies individuals.

Answer:

• 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.
• Response variable: D. The variable is qualitative because it classifies the individual.
