A statistic describes a sample, while a parameter describes an entire population. A sample is a smaller subset that is representative of a larger population.


Call center quality parameters are derived from standard key performance indicators used by call center management. Common key performance indicators for call center performance include time to answer, call abandon rate, call handling time, first call resolution, transfer rate, idle time and hold ti


A variation order is a change, often in construction, that modifies all or part of an existing order. Many construction projects undergo changes, especially after the beginning of building, and the cost impact on a construction project with a variation order can be costly.


Natural variations, also known as genetic variations, are mutations that randomly occur during sex cell division. These variations lead to different phenotypes that change an offspring's ability to survive and reach sexual maturity.


The term "direct variation" refers to a mathematical correlation between two variables where one variable can be represented as a constant multiple of the other unknown quantity. It is also known as a "direct proportion."


The constant of variation is a number that relates two variables that are directly proportional to one another. The number represents a fixed ratio between the two variables, describing how they correspondingly increase or decrease. Constants of variation cannot be calculated for linear expressions


The general formula for direct variation is k equals y divided by x. In this formula, k is a constant quantity and x and y are variables. K is also called the constant of variation, because it stays the same even as x and y vary.


Direct variation exists when a worker is paid based on the number of hours worked. Another example of a direct variation is a taxi fare that varies according to the distance traveled. Direct variation occurs with two variables when the ratio of their values always remains the same. For example, if t


Cultural variation refers to the differences in social behaviors that different cultures exhibit around the world. What may be considered good etiquette in one culture may be considered bad etiquette in another.


Variation, a term in genetic science, refers to a genetic change that causes differing characteristics between organisms in a certain species. Much of the variation within and between species is due to differential regulation of genes and alleles. Gene alleles determine distinct traits passed on fro
