confidence level

a value expressing the frequency with which a given confidence interval contains the true value of the parameter being estimated. For example, a 95% confidence level associated with a confidence interval for estimating a population mean indicates that in 95% of all estimates based on a random sample of a given size the confidence interval will contain the true value of the population mean. The particular confidence level used is up to the researcher but generally is 95% or 99%.

Kruskal–Shepard scaling

a type of multidimensional scaling applied to judgments of similarity or dissimilarity for pairs of items (e.g., cities). The dissimilarities are represented by distances between items in a highly dimensional space: Larger distances indicate greater dissimilarity. [William Henry Kruskal (1919–2005), U.S. statistician; Roger N. Shepard (1929– ), U.S. experimental and cognitive psychologist]
