I am having issues explaining my sampling technique in my methodology. I have utilised a two phase sequential explanatory design collecting and analysing the Quantitative data in the form of an online survey first, followed by collecting and analysing the Qualitative-which is a consumption diary. The only stipulation was that participants had to be of a certain age Those who took part in the online survey (obtained via social media and general advertising) were asked to contact the researcher if they would like to take part in the consumption diary, thus I obtained my sample for the second phase of the research.
Any ideas what this would be labelled as? I have been reading journal after journal, but I am still not any further forward,
Thanks in advance,
Jen.
Your sample for the second phase is called a "volunteer sampling".
It doesn't sound like you had any "eligibility" requirements, and just accepted anyone who was willing to complete both the first survey and the later diary. In that case, the would each be a "convenience" sample.
Jen - You have used "Judgment sampling technique", it is an extension of convenience sampling based on judgement. For example , you have used a stipulation that participants had to be of a certain age, thus using some judgment. David L Morgan is very correct in saying that you had accepted anyone who was willing to complete both the first survey and the later diary and in that case, it is a "convenience" sample. Convenience sampling is also called as accidental sampling and is based on using participants who are a captive audience or shows special interest in research. But in your case, it can be called as "Judgment sampling" because you have used some judgment while choosing a convenience sample.
although you have used a criteria to select your sample,but that criteria is related to your topic,from among them you hvae done a random sampling method of selection.
