But, both the methods and approaches (qualitative and quantitative) have pros and cons. This study, therefore, aims to discuss the advantages and disadvantages of using qualitative and quantitative research approaches and methods in language testing and assessment research.

Purposive sampling becomes useful in this situation, because it offers a wide selection of non-probability sampling techniques. For example, a researcher can use critical case sampling to determine if a phenomenon is worth investigating further. Then, he can use expert sampling to examine specific issues. Poor research methods will always result in poor data. The advantages and disadvantages of random sampling show that it can be quite effective when it is performed correctly. Random sampling removes an unconscious bias while creating data that can be analyzed to benefit the general demographic or population group being studied.

Advantages and disadvantages of probability sampling: Advantages: Since it is done at random, the whole process is unbiased. This is good to use in smaller populations, of course it doesn't 100% protect from bias (depending on the question).
