Hypothesis Testing Assumptions

For its validity, all hypothesis testing depends heavily on the assumption that the sample was drawn using probability sampling techniques. For this discussion, answer the following:

• Why is it important that a sample be random?
• What can you do if you cannot use a probability sampling technique? (For example, suppose there is no good sampling frame available for the population of interest.)
• Provide an example of a population and explain how you would collect a random sample from that population.

Response Guidelines

Respond to the posts of at least two peers by sharing:

• Insight as to why probability sampling techniques are important.
• Your evaluation of your peer's suggestions for alternatives to probability sampling.
• Suggestions for how to collect a random sample from the identified population.
