The Poisson, the negative exponential, and the rectangular distributions,proximation); if we know that, on the average, 10 particles arrive in a minute, then the number that arrive in any given hour will not necessarily be 10 × 60 = 600. So the probability distribution of the arrival of other numbers, e.g. 610 or 579, is of considerable importance.

Regression curves and lines, correlation coefficient, normal bivariate distribution,have noticed that tall fathers tend to have tall sons; but are the sons shorter or taller . than their fathers? After all, some tall fathers have short sons and vice versa.) Suppose observations of a large number of heights of father and son have been made and that this data has to be analysed.

Note on sampling techniques and quality control,oved unsatisfactory, particularly for plants. Even the most careful experimenter seems to have a bias in some direction, and, unconsciously, tends to select those which are larger, or smaller, or greener, etc.

https://doi.org/10.1007/978-3-319-13057-6Often the best way to understand a subject is to trace its historical development and, pursuing this policy, we note that the word ‘statist’ first appeared in the English language while Shakespeare was a young man (.. 1584). It meant ‘a person knowledgeable in state affairs’ as might be inferred from the quotation above.
