No causation without manipulation
| Glossary of Statistical Terms |
A slogan attributed to paul holland. if the conditions were not deliberately manipulated (for example, if the situation is an observational study rather than an experiment), it is unwise to conclude that there is any causal relationship between the outcome and the conditions. see post hoc ergo propter hoc and cum hoc ergo propter hoc.

Deck of cards, английский
A standard deck of playing cards contains 52 cards, 13 each of four suits: spades, hearts, diamonds, and clubs. the thirteen cards of each suit are {ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king}. the face cards are {jack, queen, king}. it is typically assumed that if a deck of cards is shuffled well, it is equally likely to be in each possible ordering. there are 52! (52 factorial) possible orderings.
Simple random sample, английский
A simple random sample of n units from a population is a random sample drawn by a procedure that is equally likely to give every collection of n units from the population; that is, the probability that the sample will consist of any given subset of n of the n units in the population is 1/ncn. simple random sampling is sampling at random without replacement (without replacing the units between draws). a simple random sample of size n from a population of n ≥ n units can be constructed by assigning a random number between zero and one to each unit in the population, then taking those units that were assigned the n largest random numbers to be the sample.
