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.
