Question

Owners of a radio station want to obtain information on the online radio listening habits in Spain. The station sends a survey out to those listeners with email addresses. Which of the following sampling designs best represents the type of survey design described?

a) A cluster sample using the cities in clusters
b) A convenience sample from the entire country
c) A simple random sample from the entire country
d) A stratified sample from the entire country

Answer 1

The best sampling design for obtaining information on online radio listening habits in Spain is a stratified sample from the entire country.

Step-by-step explanation:

The best sampling design for the given scenario of obtaining information on online radio listening habits in Spain is d) A stratified sample from the entire country.

In this case, the radio station wants to gather information from online radio listeners in Spain, so the entire country serves as the population.

A stratified sample is appropriate because the station can divide the population into different strata (such as age groups, gender, or geographic regions) and randomly select participants from each stratum. This ensures a representative sample and provides a fair chance for every online radio listener in Spain to be included.
