When collecting statistical data, what is the value of using a random sample versus a sample of an entire population.

Sampling the entire population is time consuming. You can use random sampling as long as you collect enough data. There are tables you can use to determine the number of random samples based on the population to ensure reliability and validity. A random sample is viable when the population is large.
