Learning Goal: I'm working on a writing question and need an explanation and answer to help me learn. This week covers probability and non-probability sampling. Discuss in detail the characteristics of probability and nonprobability sampling. Discuss why researchers would use conditional probability instead of unconditional probability in their study. Embed course material concepts, principles, and theories (which require supporting citations) in your initial response along with at least one scholarly, peer-reviewed journal article. Keep in mind that these scholarly references can be found in the Digital Library by conducting an advanced search specific to scholarly references. Use Electronic University academic writing standards and APA style guidelines. You are required to reply to at least two peer discussion question post answers to this weekly discussion question and/or your instructor’s response to your posting. These post replies need to be substantial and constructive in nature. They should add to the content of the post and evaluate/analyze that post’s answer. Normal course dialogue doesn’t fulfill these two peer replies but is expected throughout the course. Answering all course questions is also required.
