i read about the sampling issues on mixed method design by Onwuegbuzie & Collins (2007).Could anyone suggested to me reliable books on these.I am still vague in their suggested parallel and nested sampling.Please help me.
I’ve been browsing the resources and found a refernce Resources – links – mix methods: “Mixed methods sampling: (Kemper, Stringfield, & Teddlie, 2003). This is a simultaneous selection of units of study through both probability (to increase generalizability/transferability) and purposive sampling strategies (to increase inference quality).” http://www2.fiu.edu/~bridges/glossary.htm
