What is the best non probability sampling method?

One of the best non-probability sampling methods is purposive sampling, also known as judgmental sampling. This method involves selecting participants based on specific characteristics or criteria relevant to the research question, ensuring that the sample is well-suited to provide insights into the topic. It allows researchers to focus on specific subgroups, making it particularly useful in qualitative research where depth of understanding is prioritized over generalizability. However, it's essential to acknowledge that findings from purposive sampling may not be representative of the broader population.
