Document Summary
When we sample a larger amount of people, we don(cid:495)t just take anybody we tailor the sample but picking and choosing who is being sampled. Probability: equal & independent probability of selection, need complete frame, rarely used. Purposive: use something for a reason. Purposive sampling: hand-pick (cid:494)typical(cid:495) elements using specific criteria, useful if small sample numbers in rare diseases. Snowball /network sampling: useful for hard-to-locate elements. Find participants then have participants name others they. Theoretical sampling know with same condition: used in grounded theory research to build theory. Depends on research tradition used: phenomenology, ethnographic, grounded theory. Greater concern is how / if data saturation is reached. I want to conduct a qualitative examination of how nursing students feeling/experiences/etc. (cid:523)*some qualitative word here(cid:524) about (cid:494)nursing research(cid:495) With this type of qualitative research, you really get to feel how these people actually feel. I want to collect information from a wide variety of students.
