Numerical characteristic of a population
WebA parameter is a numerical characteristic of the whole population that can be estimated by a statistic. Since we considered all math classes to be the population, then the average number of points earned per student over all the math classes is an example of a parameter. WebThe population has the following characteristics: 1. Population Size and Density: Total size is generally expressed as the number of individuals in a population. ADVERTISEMENTS: Population density is defined as the numbers of individuals per unit area or per unit volume of environment.
