researchers call random radio listeners on the phone to rank five different popular songs. this research helps radio stations decide which songs to play more often. this method of gathering data is classified as\n\na census.\n\na sample survey.\n\nan experiment.\n\nan observational study.
Answer
Brief Explanations:
A census involves collecting data from an entire population. Here, only random radio - listeners are called, not the entire population of radio - listeners, so it's not a census. An experiment involves manipulating variables, which isn't the case here as researchers are just asking for rankings. An observational study involves observing behavior without interfering, but here researchers are actively asking for rankings. A sample survey involves collecting data from a subset (sample) of the population, which is what's happening as random radio - listeners (a sample of all radio - listeners) are called to rank songs.
Answer:
B. a sample survey.
