Question

Random cell phone calls sent out to a sample size of 850 people is what type of sampling method? (I.e. simple random, etc.)?

Answer 1

Random cell phone calls sent out to a sample size of 850 people would typically be considered a form of random sampling. However, the specific type of random sampling can vary. It could be simple random sampling if each person in the population has an equal chance of being called, and the selection is done entirely by chance, such as using a random number generator to select phone numbers.

Alternatively, it could be stratified random sampling if the population is divided into different groups or strata (e.g., age groups, geographic regions), and then random samples are taken from each stratum in proportion to its size.

The exact method used depends on the sampling strategy and goals of the study, but as long as the selection of individuals is based on randomness and each person has an equal chance of being included, it falls under the broad category of random sampling.

Answer: Simple Random Sampling (SRS)

The people chosen are basically picked out of a hat at random, though likely they are chosen by a computer.
