How large do you think your population and sample will need to be for your dissertation research? Explain your reasoning. What factors other than size will you consider in relation to sampling? Why? What types of descriptive statistics will you consider for summarizing the sample? Why?A researcher must identify a population in which the study is based upon investigating, while the sample is the portion that represents the population which data is collected; for example, a study could investigate a topic involving the graduating class at a local University which is a total of 425 students, this would be considered the population but through the random selection process only 250 of those students are slated to participate, representing the sample.Researchers must determine the sample size as this is an important step because not only does the sample represent the number of participants that are to be studied from the population, but it should also be comparative to the goals of the study; Lenth (2001) states the sample size should be large enough but not too large to be considered of scientific significance. The sample size is important as it influences how accurately the sample represents its population (Gravetter
