Answer to Question #200722 in Statistics and Probability for carlstien jane

Question

1. If a sample is used, what type of sampling technique would gain the most valid information? How can the researchers be certain that the sample of workers is representative of the population?

Answer 1

If you want to produce results that are representative of the whole population, probability sampling techniques are the most valid choice.

One of the best probability sampling techniques that helps in saving time and resources, is the Simple Random Sampling method. It is a reliable method of obtaining information where every single member of a population is chosen randomly.

Samples must be representative of the chosen population studied. They must be randomly chosen, meaning that each member of the larger population has an equal chance of being chosen. They must be large enough so as not to skew the results.
