In mathematics, a ranked poset is a partially ordered set in which one of the following (non-equivalent) conditions hold: it is a graded poset, or; a poset with the property that for every element x, all maximal chains among those with x as greatest element have the same finite length, or; a poset in which all maximal chains have the same ...
The rank is consistent with the covering relation of the ordering, meaning that for all x and y, if y covers x then ρ(y) = ρ(x) + 1. The value of the rank function for an element of the poset is called its rank. Sometimes a graded poset is called a ranked poset but that phrase has other meanings; see Ranked poset.

The Education Index is a component of the Human Development Index (HDI) published every year by the United Nations Development Programme. Alongside the economical indicators ( GDP ) and Life Expectancy Index , it helps measure the educational attainment .
For instance, the acknowledgement of differences in rank curbs aggressive behavior. [6] Ranking also functions as a channel through which social control and resources are allocated. Thus, the purpose of the social rank system is to remain attuned the social hierarchy to better compete for rank, and consequently expand resource acquisition. [2] [4]
Sociometric status is a measurement that reflects the degree to which someone is liked or disliked by their peers as a group. While there are some studies that have looked at sociometric status among adults, the measure is primarily used with children and adolescents to make inferences about peer relations and social competence.
