The rule can then be derived [2] either from the Poisson approximation to the binomial distribution, or from the formula (1−p) n for the probability of zero events in the binomial distribution. In the latter case, the edge of the confidence interval is given by Pr(X = 0) = 0.05 and hence (1−p) n = .05 so n ln(1–p) = ln .05 ≈ −2
The 1-2-3 drinking rule helps prevent alcohol abuse. The limits are no more than one drink per hour, two drinks per occasion and three drinks per day. To cut down on drinking, try the 1-2-3 rule
In statistics, the 68–95–99.7 rule, also known as the empirical rule, and sometimes abbreviated 3sr or 3 σ, is a shorthand used to remember the percentage of values that lie within an interval estimate in a normal distribution: approximately 68%, 95%, and 99.7% of the values lie within one, two, and three standard deviations of the mean ...
This rule is also called the oversmoothed rule [7] or the Rice rule, [8] so called because both authors worked at Rice University. The Rice rule is often reported with the factor of 2 outside the cube root, 2 ( n ) 1 / 3 {\displaystyle 2\left(n\right)^{1/3}} , and may be considered a different rule.

The theory of statistics provides a basis for the whole range of techniques, in both study design and data analysis, that are used within applications of statistics. [1] [2] The theory covers approaches to statistical-decision problems and to statistical inference, and the actions and deductions that satisfy the basic principles stated for these different approaches.
A photoblog (or photolog) is a form of photo sharing and publishing in the format of a blog. It differs from a blog through the predominant use of and focus on photographs rather than text. Photoblogging (the action of posting photos to a photoblog) gained momentum in the early 2000s with the advent of the moblog and cameraphones.
This proposition is (sometimes) known as the law of the unconscious statistician because of a purported tendency to think of the aforementioned law as the very definition of the expected value of a function g(X) and a random variable X, rather than (more formally) as a consequence of the true definition of expected value.
