In statistics, stratified sampling is a method of sampling from a population which can be partitioned into subpopulations. In statistical surveys, when...

the estimation of the variance of a continuous distribution from a sample of that distribution. We take a sample with replacement of n values Y1, .....

electronics, a sample and hold (also known as sample and follow) circuit is an analog device that samples (captures, takes) the voltage of a continuously...

uses the studentized range distribution. Suppose that we take a sample of size n from each of k populations with the same normal distribution N(μ, σ2)...

outcomes or results of that experiment. A sample space is usually denoted using set notation, and the possible ordered outcomes, or sample points, are listed...

Sample size determination or estimation is the act of choosing the number of observations or replicates to include in a statistical sample. The sample...

function. Inverse transformation sampling takes uniform samples of a number u {\displaystyle u} between 0 and 1, interpreted as a probability, and then returns...

A core sample is a cylindrical section of (usually) a naturally-occurring substance. Most core samples are obtained by drilling with special drills into...

In statistics, a sampling distribution or finite-sample distribution is the probability distribution of a given random-sample-based statistic. If an arbitrarily...

of a set of numbers is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data...

The polar form takes two samples from a different interval, [−1,+1], and maps them to two normally distributed samples without the use of sine or cosine...

that can be measured on a continuous scale, such as weight, temperature, thickness etc. For example, one might take a sample of 5 shafts from production...

distribution of the studentized range of an i.i.d. sample from a normally distributed population. Suppose that we take a sample of size n from each of k populations...

The NASA-ESA Mars Sample Return is a proposed Flagship-class Mars sample return (MSR) mission to collect Martian rock and soil samples in 43 small, cylindrical...

A chi-squared test (also chi-square or χ2 test) is a statistical hypothesis test used in the analysis of contingency tables when the sample sizes are...

vendors. Sample sales are often associated with the fashion industry. These sales are an opportunity to get near perfect merchandise at a fraction of the price...

of oxygen and the amount of right-to-left cardiac shunt, which are both clinically useful quantities. However, it is not practical to take a sample of...

Nyquist–Shannon sampling theorem is an essential principle for digital signal processing linking the frequency range of a signal and the sample rate required...

In general, a sample is a limited quantity of something which is intended to be similar to and represent a larger amount of that thing(s). The things...

Mary to take a sample of the walls and send it in for analysis. Mary and Simon grow closer, eventually sleeping together. While she sleeps, a dragonfly...
