Sampling techniques for IA

Recommended Posts

Will I be marked down for using opportunity sampling instead of random sampling?

I know that it's better to do random sampling but it inconveniences everyone else. 

If I discuss the flaws in my sampling will it be ok?

They don't mind at all if you do a convenience sample, in fact its pretty much the standard. 
I'd recommend bring it up as a flaw in your experiment in the discussion and suggesting the use of a purposive sample for greater symbolic representation and hence representational generalisability. But what you're doing sounds A. OK. to me.
