The sample is a subset of factual numbers that are categorized by size, quality, and quantity. However, the population is the collection of elements or items in a distribution. The population distribution contains elements of the whole group. However, specific subsets of the elements are included in a sample. The parameter and statistics describe the difference between a sample and population distribution. Parameters describe data in the population, while a statistic describes values in a sample distribution.
Census is the process used for collecting information from the population. However, the survey method is used to collect information from a sample distribution. The focus on population and sample is to identify the characteristics of elements in the distribution. Despite the above differences, sample and population are similar because the sample is a part of the population distribution. They form elements used to describe the measures of dispersion and central tendency.
