What is sample design and its types?
Thus, sample designs are basically of two types viz., non-probability sampling and probability sampling. We take up these two designs separately. Non-probability sampling is also known by different names such as deliberate sampling, purposive sampling and judgement sampling.
How do you conduct a convenience sample?
How to efficiently analyze convenience sampling data?
- Take multiple samples. It helps you in producing reliable results.
- Repeat the survey to understand whether your results truly represent the population.
- For a big sample size, try cross-validation for half the data.
What is descriptive analysis in research?
