The sampling procedure is the method of selecting from a community when the decision is based on the randomization principle, often known as opportunity or representative sample. In general, probability sampling is more complex, time-consuming, and expensive than non-probability selection. However, since units from the population are chosen at random, and the selection probability for each team can be determined, accurate estimates can be generated, and statistical conclusions about the people may be drawn (Etikan & Bala, 2017). The objective when selecting a chances methodological approach is to reduce survey time and expense while simultaneously limiting the confidence intervals of projections for the most crucial considering all the factors.
A qualitative study technique known as an interview relies on the collection of data through the use of questions. Without a doubt, a face-to-face interview will record both verbal and non-verbal cues. However, this method also allows for the recording of non-verbal signs like body language, which might show how uncomfortable someone is with the inquiries. On the other hand, it can also reveal a candidate’s level of interest in the interview’s subjects. However, the quality of the information that individuals receive frequently depends on the interviewer’s skills. A potential ethical problem may be that the interviewees will not want to talk about their illness to the interviewer. However, in order to solve this problem, the interviewer must say that this interview is anonymous and all data will be presented only with the consent of the interviewees; thus, ethical issues can be avoided.
Both reliability and validity refer to whether the testing of ideas is correct; reliability can be defined as a measure’s regularity, and validity is defined as a measure’s correctness. In the case of the chosen topic, the pain experienced by the interviewees can be analyzed as a reliability factor. Validity will be confirmed after collecting information on pain and confirming the hypotheses set in the study.
