MANAGEMENT

Detailed explanation-1: -A representative sample is used in statistical analysis and is a subset of a population that reflects the characteristics of the entire population.

Detailed explanation-2: -The sampling unit is the unit of the population that we select in our sample. Note: Before selecting the sample, the population must first be divided into non-overlapping sampling units. Sometimes the sampling unit is the element itself. Sometimes the sampling unit is a group of more than one element.

Detailed explanation-3: -A good maximum sample size is usually 10% as long as it does not exceed 1000. A good maximum sample size is usually around 10% of the population, as long as this does not exceed 1000. For example, in a population of 5000, 10% would be 500. In a population of 200, 000, 10% would be 20, 000.

Detailed explanation-4: -A bias can arise when measuring a nonlinear functional of the probabilities from a limited number of experimental samples even when these samples are truly randomly picked from the underlying population and there is thus no sampling bias. This bias is called “limited sampling bias”.
