Parent topics
- Mathematics [r]: The study of quantities, structures, their relations, and changes thereof. [e]
- Scientific method [r]: The concept of systematic inquiry based on hypotheses and their testing in light of empirical evidence. [e]
Related topics
- Statistics theory [r]: A branch of mathematics that specializes in enumeration, or counted, data and their relation to measured data. [e]
- Free statistical software [r]: This article briefly describes what free software is available for conducting statistical analysis of data. [e]
- Factor analysis [r]: Statistical technique used to explain variability among observed random variables in terms of fewer unobserved random variables called factors. [e]

Glossary
- Confidence interval [r]: the range of a random variable, such as the mean of a sample, that — with a specified probability — contains the true value for the population. [e]
- Confidence level [r]: the probability that the true value of a random variable lies within the estimated (or predicted) confidence interval. [e]
- Deterministic [r]: the predictable effect of known causes (used in contrast to stochastic). [e]
- False positive rate [r]: the proportion of tests that yield a positive result when the true result is negative. [e]
- False negative rate [r]: the proportion of tests that yield a negative result when the true result is positive. [e]
- Mean [r]: e.g. "arithmetic mean", being the sum of n observations divided by n, or "geometric mean", being the nth root of the product of n observations. [e]
- Median (statistics) [r]: The value of a numerical or linearly ordered sample for which one half of the observations lie above and one half lie below that value. [e]
- Mode (statistics) [r]: the most frequently ocurring value. [e]
- Normal distribution [r]: a symmetrical bell-shaped probability distribution representing the frequency of random variations of a quantity from its mean. [e]
- Population (statistics) [r]: the totality of the people or things that constitute the category that is the subject of a statistical investigation, and from which a sample is drawn. [e]
- Prevalence [r]: The total number of cases of a given disease in a specified population at a designated time. It is differentiated from incidence, which refers to the number of new cases in the population at a given time. [e]
- Sample (statistics) [r]: An instance of a random variable used to estimate one or several of its parameters. [e]
- Standard deviation [r]: A statistical measure for the fluctuation of a random variable about its mean value (the square root of the variance). [e]
- Standard error [r]: the standard deviation of the variation of a statistic that would occur if the same sampling method were applied repeatedly: for example, the standard error of the mean is measured as the standard deviation of the observed (sample) mean as measured in independent samples of a given size.
