Sampling is a technique where a small proportion of data is selected at random out of a population and is used to estimate the characteristics of the whole population. The outcome from the sampling can be close or similar to that of the result of using the population data set. The differenc...
Some methods are better than others, but they might be more difficult. Different Types of Sampling Methods Random Sampling A random sample is where every member of the population has anequal chanceto be chosen. Random sampling is the best. But, it can be difficult, or impossible, to make ...
He/she numbers each element of the population from 1-5000 and will choose every 10th individual to be a part of the sample (Total population/ Sample Size = 5000/500 = 10). Stratified random sampling: Stratified random sampling is a method in which the researcher divides the population into...
