Review the critical elements that must be addressed in the final project. Use this worksheet to create Milestone Two.
- is a subset of a population.
- is a type of sample. Every element of the population has an equal chance of selection into this kind of sample.
- If a researcher takes a random sample from a population, he or she can conclude the sample mirrors the population. He or she can also conclude research on the sample will be the same as what one would find with the population.
- The larger the size of a sample, the more a sample resembles the population.
- Whether a researcher sampled randomly, and the size of the sample, affects results. Random, large samples provide bases for stronger, more reliable conclusions. Convenience (non-random) samples and/or smaller samples provide the bases for weaker and less reliable conclusions.
- No line divides a "small" sample from a "large" sample. As a guiding start, though, a researcher considers fewer than n = 30 to be relatively small.
- If a researcher divides a sample into groups, this division does not change sample size.
- See Chapter 1 of Statistical Reasoning for Everyday Life for additional information on sampling.
- Indicate the sample size (n = ), and describe what consequence this sample size will have on your analyses and on your reporting of results.
- Choose a statistical procedure and explain how the statistical procedure you choose will help to answer your research question. [For this question, refer to the Choose Your Test document.]
