Answer: A purposive sample is a place where a specialist chooses a Sample in view of their insight regarding the review and population. The selection criteria the researcher uses can be very arbitrary and are almost always subjective. Because the generalizability of convenience samples is unclear, the estimates derived from convenience samples are often biased (i.e., sample estimates are not reflective of true effects among the target population because the sample poorly represents the target population). It can be regarded as a numerical characteristic of a population or a model. An effective research study requires a good rapport between the researcher and the respondents. 4 Disadvantage: Lost Data.

Systematic sampling. Sampling gives more time to researcher for data collection, so it is quickly and has a lot of time for collection of inflammation. Research is of value only when the findings from a sample can be generalized to a meaningful population. In straightforward terms, Sampling is the course of determination of the set number of components from a huge gathering of components (population) so that, the qualities of the Samples taken is indistinguishable from that of the population. Thus the term standard error is used to refer to the standard deviation of various sample statistics, such as the mean or median. In this type of sampling, subjects are chosen to be part of the sample with a specific purpose in mind. The sampling errors are also known as error variances. For research, a frame of the population is to be constructed which will enable the researcher to draw the sample, e.g., names from the census records or telephone directory, etc., for conducting a study on a sample that is drawn from the frame.
