According to expectation states theory, gender status beliefs attribute greater competence and social status to men than women. Similar to Eagly's Social-Roles Theory, [5] expectation states theory holds that gender stereotypes are prescriptive in nature, meaning the stereotype regards not only the way things are but the way they should be ...
Joseph Berger (April 3, 1924 – December 24, 2023) was an American sociologist and social psychologist best known for co-founding expectation states theory. [1] Expectation states theory explains how individuals use social information about one another (such as race, gender, or specific skills) to create informal status hierarchies in small groups.
In probability theory, the expected value (also called expectation, expectancy, expectation operator, mathematical expectation, ... Fatou's lemma states that ...
The proposition in probability theory known as the law of total expectation, [1] the law of iterated expectations [2] (LIE), Adam's law, [3] the tower rule, [4] and the smoothing theorem, [5] among other names, states that if is a random variable whose expected value is defined, and is any random variable on the same probability space, then
Cecilia L. Ridgeway is an American sociologist and the Lucie Stern Professor of Social Sciences, Emerita in the Sociology Department at Stanford University.

This list of countries by life expectancy provides a comprehensive list of countries alongside their respective life expectancy figures. The data is differentiated by sex, presenting life expectancies for males, females, and a combined average.
In quantum mechanics, the expectation value is the probabilistic expected value of the result (measurement) of an experiment. It can be thought of as an average of all the possible outcomes of a measurement as weighted by their likelihood, and as such it is not the most probable value of a measurement; indeed the expectation value may have zero probability of occurring (e.g. measurements which ...
Perceived performance refers to a person’s perceptions of the actual performance of a product, service, or technology artifact. According to expectation confirmation theory, perceptions of performance are directly influenced by pre-purchase or pre-adoption expectations, and in turn directly influence disconfirmation of beliefs and post-purchase or post-adoption satisfaction.
