Operations research (or operational research) is an interdisciplinary branch of applied mathematics and formal science that uses methods such as mathematical modeling, statistics, and algorithms to arrive at optimal or near optimal solutions to complex problems; Management science focuses on problems in the business world.
Social statistics is the use of statistical measurement systems to study human behavior in a social environment. This can be accomplished through polling a group of people, evaluating a subset of data obtained about a group of people, or by observation and statistical analysis of a set of data that relates to people and their behaviors.
The function was real-valued and differentiable. It was specified to describe the society as a whole. Arguments of the function included the quantities of different commodities produced and consumed and of resources used in producing different commodities, including labor. Necessary general conditions are that at the maximum value of the function:
In that case the society needs to be an open system. In order to increase the redundancy in the distribution category of a society as a closed system, entropy needs to be exported from the subsystem operating in that economic category to other subsystems with other entropy categories in the society. For example, social entropy may increase.
The word statistics ultimately comes from the Latin word Status, meaning "situation" or "condition" in society, which in late Latin adopted the meaning "state". Derived from this, political scientist Gottfried Achenwall, coined the German word statistik (a summary of how things stand).
If we take the 80% rule to apply via the odds ratio, this implies that the threshold odds ratio for assuming discrimination is 1.25 – the other measures of effect size are therefore: =, =, =, (>) = This implies that discrimination is presumed to exist if 0.4% of the variation in outcomes is explained and there is a 0.123 standard deviation ...
Manifest functions are the consequences that people see, observe or even expect. It is explicitly stated and understood by the participants in the relevant action. The manifest function of a rain dance, according to Merton in his 1957 Social Theory and Social Structure, is to produce rain, and this outcome is intended and desired by people participating in the ritual.
[148] The ratio also depends on the type of war, for example in the Falklands War 904 of the 907 dead were men. Conversely figures for war deaths in 1990, almost all relating to civil war, gave ratios in the order of 1.3 males per female. Another opportunity to tackle gender inequality is presented by modern information and communication ...
