Then squares should be picked at random until you have the number of samples needed, the easiest way of picking at random is to number each grid square and then use a random number generator (easily found on the internet or on a calculator) to chose numbers which then relate to a grid square. A randomized controlled trial is a study where people get allocated by chance alone to receive one of several unique clinical interventions. When there is elicitation, accepted criteria, or a theoretical framework in place, then this issue is minimized. Random Sampling :- Sampling using random numbers, where each item in the parent population must have an equal chance of being selected for the sample.

Researchers must provide evidence that the judgment used to select the various units or individuals in the purposive sampling was appropriate for the processed used. Quantitative approaches to research include hard numbers and provable results, such as experiments and surveys. Advantages of Theoretical Sampling The possibility to strengthen the rigor of the study if the study attempts to generate a theory in the research area.

Theoretical sampling is a process of data collection for generating theory whereby the analyst jointly collects codes and analyses data and decides what data to collect next and where to find them, in order to develop a theory as it emerges. If the proportions of the sub-sets are known, it can generate results which are more representative of the whole population.
