What is the average sample size for qualitative research?
Sample Size for Qualitative Studies Need to ensure there is enough, but not too much, data (>30 too large; Boddy, 2016). One review identified that samples of 20 and 30 (and multiples of 10) were most common (Mason, 2010), with 25-30 being a typical recommendation (Dworkin, 2012).
How many participants are needed for a qualitative study?
While some experts in qualitative research avoid the topic of “how many” interviews “are enough,” there is indeed variability in what is suggested as a minimum. An extremely large number of articles, book chapters, and books recommend guidance and suggest anywhere from 5 to 50 participants as adequate.
