Sampling designs fit into one of two categories: probability or non-probability. Probability designs use random selection. Random selection means that every member of the sample has an equal chance of being selected. Your textbook explains four common probability sampling designs: simple random sampling, systematic sampling, stratified random sampling, and cluster sampling.

Non-probability designs do not include random selection. Your textbook explains four common non-probability sampling designs: convenience sampling, purposive sampling, quota sampling, expert sampling, and snowball sampling.

Assignment:

1. Select one sampling design in the probability category and one sampling design in the non-probability category and write a brief description of each of the two sampling designs you selected.
2. For each sampling design, explain how using that design could either adhere to or violate the justice principle. Explain how and why. Be specific.

Note: Identify the two sampling designs you discussed in the first line of your post.
