Sampling
In qualitative and quantitative studies, sampling refers to selecting a particular sample of individuals from a larger population. This process is often called participant selection. Qualitative research collects rich data from fewer sources, while quantitative research attempts to collect a larger, more representative sample from the population as a whole. Selection criteria for eligibility in a study is similar for both quantitative and qualitative studies, however, there are some differences with respect to the procedures used and the size of the samples.
Instructions:
Consider a particular topic (this can be the topic from one of your previous discussions or assignments), and a particular qualitative or quantitative research design and state the factors you would consider in choosing participants for the study. Be sure to answer the following in your discussion:
- What sampling method would you use?
- How would you go about deciding how many participants to select given a particular methodology?
What factors should be considered regarding sample size, representativeness, and apparent biases in the selection of the sample?

Answer previewSampling design and effective population representation are fundamental determinants of quality research findings. Sampling refers to a statistical process of selecting suitable subset of a population with specified characteristics for analysis and making conclusion about the entire population based on the findings (Malec & Newman, 2013). Sampling is preferred to a census to its effectiveness in time used to conduct enumeration and inexpensiveness. Different types of sampling methods include simple random, stratified, clustered and systematic sampling (Valerio et al., 2016). We are interested in…(450 words)
