Purposive sampling involves selecting participants for a study based on some characteristic that you know they have. There is nothing random about their selection - it was done with intent. An advantage of this type of sampling is that it allows the researcher to quickly hone in on the target population. A disadvantage to this form of sampling is that researcher bias can creep in to influence results, if subjects are not chosen very carefully.

sampling theorem is used to know about sample signal.
in flat top sampling the electronic circuit required for sampling are less complicated as compared to the one used in natural sampling, at demodulation of the sample it is very difficult to maintain the natural waveform of the natural sampling so flat top sampling can easily be demodulated.
The sampling proportion may be used to scale up the results from a sample to that of the population. It is also used for designing stratified sampling.
Purposive sampling can allow the researcher to make generalizations about results. Purposive sampling also provides the researcher with many different sampling techniques.

An advantage of this type of sampling is that it allows the researcher to quickly hone in on the target population. A disadvantage to this form of sampling is that researcher bias can creep in to influence results, if subjects are not chosen very carefully.
Purposive sampling, also known as judgmental or non-probability sampling, is used when researchers want to select participants based on specific characteristics or qualities that are relevant to the study. This method is typically employed when the research requires in-depth insights from a particular subgroup, making it suitable for qualitative research. It allows researchers to focus on individuals who can provide the most relevant information rather than a random selection of participants.
Non-probability sampling techniques do not require a sampling frame. Examples include convenience sampling, where subjects are selected based on availability, and purposive sampling, where participants are chosen based on specific characteristics or criteria relevant to the research. These methods rely on the researcher's judgment rather than a complete list of the population. However, they may introduce bias and limit the generalizability of the findings.

The sample mean helps researchers maintain the scope of their research. If the sample mean is too far from the mean of the population then the numbers may be skewed.

The sampling design you are referring to is called "purposive sampling" or "judgmental sampling." In this approach, researchers select individuals based on specific criteria or characteristics that align with the study's objectives, often to ensure that certain controls are maintained. This method allows for a focused investigation of particular traits or behaviors, but it may introduce bias since the sample is not randomly selected.
