Answer: random sampling
Explanation: Random sampling is a part of the sampling technique which each sample has an equal probability of being chosen. A situatuon whereby sample chosen randomly is supposed to be an unbiased representation of the total population. If at all, when sample does not represent the population, then the variation is called a sampling error.
Description: Random sampling is one of the easiest ways of collecting data from the total population. In random sampling, each member of the subset carries an equal opportunity of being part of the sampling process. For example, the total workforce in from is 500 and to conduct a survey, a sample group of 50 employees is selected to do the survey. In this scenario the population is the total number of employees in the firm and the sample group of 50 employees is the sample. Every member of the workforce has the same opportunity of being chosen because all the employees which were chosen to be part of the survey were selected randomly. But, when there is a possibility that the group or the sample does not represent the population as a whole, that means, any random variation is termed as a sampling error.
Another example of a simple random sample would be the names of 25 employees being chosen out of a group of company of 250 employees. In this case, the population is all 250 employees, and the sample is random because each employee has an equal chance of being chosen.
Random sampling is usually used in science to conduct randomized control tests or for blinded experiments.
Given that racial-ethnic identities, religious affiliations, and social ties that distinguish a group of individuals who live close to one another may be conceived of as weighted sums, I think that regional subcultures will become more unique over the next 20 years.
<h3>What purpose do subcultures serve?</h3>
Subcultures are crucial in helping people define their identities, feel a feeling of community, and think about how they fit into broader societal norms; nevertheless, they differ from widely accepted identity categories like ethnicity.
<h3>Is a certain region a subculture?</h3>
An area of the nation whose population share behavioral patterns that are different from those of the rest of the nation can be described as having a geographic subculture based on the description of a general subculture given above.
