Population inversion. In physics, specifically statistical mechanics, a population inversion occurs while a system (such as a group of atoms or molecules) exists in a state in which more members of the system are in higher, excited states than in lower, unexcited energy states. It is called an "inversion" because in many familiar and commonly ...

The simplest estimators for population mean and population variance are simply the mean and variance of the sample, the sample mean and (uncorrected) sample variance – these are consistent estimators (they converge to the value of the whole population as the number of samples increases) but can be improved.
Literacy rate in urban areas was 87.7%, higher than rural areas with 73.5%. There is a wide gender disparity in the literacy rate in India [5] and effective literacy rates (age 7 and above) was 84.7% for men and 70.3% for women. [6] The low female literacy rate has a dramatically negative impact on family planning and population stabilisation ...
In statistics, a population is a set of similar items or events which is of interest for some question or experiment. [1] A statistical population can be a group of existing objects (e.g. the set of all stars within the Milky Way galaxy) or a hypothetical and potentially infinite group of objects conceived as a generalization from experience (e ...
