# Z-factor

The Z-factor is a measure of statistical effect size. [1]

## Arithmetic mean

In mathematics and statistics, the arithmetic mean (stress on third syllable of "arithmetic"), or simply the mean or average when the context is clear, is the sum of a collection of numbers divided by the number of numbers in the collection.

## Assay

An assay is an investigative (analytic) procedure in laboratory medicine, pharmacology, environmental biology and molecular biology for qualitatively assessing or quantitatively measuring the presence or amount or the functional activity of a target entity (the analyte).

## Effect size

In statistics, an effect size is a quantitative measure of the strength of a phenomenon.

## Expected value

In probability theory, the expected value of a random variable is intuitively the long-run average value of repetitions of the experiment it represents.

## High-throughput screening

High-throughput screening (HTS) is a method for scientific experimentation especially used in drug discovery and relevant to the fields of biology and chemistry.

## Normal distribution

In probability theory, the normal (or Gaussian) distribution is a very common continuous probability distribution.

## Robust statistics

Robust statistics are statistics with good performance for data drawn from a wide range of probability distributions, especially for distributions that are not normal.

## Scientific control

A scientific control is an experiment or observation designed to minimize the effects of variables other than the single independent variable.

## Standard deviation

In statistics, the standard deviation (SD, also represented by the Greek letter sigma, σ for the population standard deviation or s for the sample standard deviation) is a measure that is used to quantify the amount of variation or dispersion of a set of data values.

## Standard score

In statistics, the standard score is the (signed) number of standard deviations an observation or datum is above the mean.

## Statistics

Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data.

## Strictly standardized mean difference

In statistics, the strictly standardized mean difference (SSMD) is a measure of effect size.
