Stat notations
The α-level upper critical value of a probability distribution is the value exceeded with probability α, that is, the value xα such that F(xα) = 1 − α where F is the cumulative distribution function. There are standard notations for the upper critical values of some commonly used distributions in statistics: • zα or z(α) for the standard normal distribution WebNotation .

( n − r)! Notice that there are a few notations. The first is more of a mathematical notation while the second is the notation that a calculator uses. WebDo Not use notation that might imply a different operation or notation than you intend. For example, don't write binomial . coefficients in a way that might look like division. 8 3 should not be written 8/3. Use "C(8,3)" or "8 choose 3" instead. § Do Not use calculator language unless all inputs are labeled. For example,
WebWe use the notation x ∼ N(μ,σ), to mean that the random variable x has normal distribution N(μ,σ). We use the same notation when x is approximately distributed as N(μ,σ). Similarly, x ∼ B(n,π) means that the random variable x has binomial distribution B(n,π), etc. for other distributions. Also note that in other statistics texts the ...
