Convergent design: conducting qualitative and quantitative research concurrently, giving equal status to qualitative and quantitative strands, analysing the qualitative and quantitative data separately, making general comment by combining the results.

Exploratory design: conducting qualitative and quantitative research sequentially, begging the study with qualitative data collection and analyses, conducting the quantitative phase based on the qualitative phase by testing
or generalizing the qualitative results, explain how the quantitative data are built on qualitative results.
