it is a method used in order to recognize suspected population status in compression with their factors
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.
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.
The two main types of sampling are probability sampling and non-probability sampling. Probability sampling involves selecting samples in a way that each member of the population has a known chance of being chosen, ensuring that the sample is representative. Non-probability sampling, on the other hand, does not provide all individuals in the population with a known or equal chance of selection, which can lead to biases in the sample. Common methods include random sampling for probability sampling and convenience or purposive sampling for non-probability sampling.
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.
Sampling has several disadvantages. These include time consuming and tedious. Possibly, members of units are different from one another, thus decreasing its effectiveness.
Purposive sampling can allow the researcher to make generalizations about results. Purposive sampling also provides the researcher with many different sampling techniques.

Propulsive Sampling Mean a sample which we can take randomly
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.
advantages: reduce bias easy of sampling disadvantages: sampling error time consuming

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.
