Convenience sampling involves selecting participants who are readily available, which can lead to biases if certain groups are underrepresented. To enhance this technique, researchers can implement stratified convenience sampling, where they identify key Demographics that are typically underrepresented and ensure that these groups are included in the sample. This might involve targeted outreach or creating quotas to ensure diverse representation. By combining convenience sampling with this additional strategy, researchers can improve the overall validity and generalizability of their findings.
A questionnaire has little to do with sampling technique. Sampling technique is to do with who gets the questionnaire and that can be any sampling technique: the questionnaire can be sent to everyone (census), to a random sample, stratified random samples, to random samples in clusters, by quota or convenience. Or a pile of questionnaires can be left for respondents to pick up - self-selection.
No. Convenience sampling involves the active participation of the researcher. It's called convenience sampling because the researcher simply grabs whomever happens to be close to hand. It's not whether people volunteer themselves. Please see the link.
convenience sampling consists of two or more sample events.
Disadvantages of systematic sampling: © The process of selection can interact with a hidden periodic trait within the population. If the sampling technique coincides with the periodicity of the trait, the sampling technique will no longer be random and representativeness of the sample is compromised.
Non-probability sampling is a sampling technique where the selection of participants is based on subjective judgment rather than random selection. This method often involves choosing individuals who are easily accessible or particularly relevant to the research, leading to a sample that may not represent the entire population. Common types include convenience sampling, judgmental sampling, and quota sampling. While it can be quicker and more cost-effective, the results may have limited generalizability due to potential biases.
You are correct; convenience sampling is not random sampling.

The difference between convenience and incidental sampling is that convenience sampling chooses the easiest people to reach when a sampling is done, whereas incidental sampling is done at random.
Two factors that affect the choice of a sampling technique are the population size and the level of accuracy required. For large populations, it may be more practical to use a random sampling technique, while for small populations, a convenience sampling technique may be sufficient. Additionally, if high accuracy is required, a stratified sampling technique may be more appropriate to ensure representation of all subgroups within the population.

Consecutive sampling is very similar to convenience sampling except that it seeks to include ALL accessible subjects as part of the sample. This non-probability sampling technique can be considered as the best of all non-probability samples because it includes all subjects that are available that makes the sample a better representation of the entire population.
