Text: Fold change is so-called as it is common to describe an increase of multiple X as an ''X-fold increase''. As such, several dictionaries, including the Oxford English Dictionary and Merriam-Webster Dictionary, as well as Collins's Dictionary of Mathematics, define ''-fold'' to mean ''times,'' as in ''2-fold'' = ''2 times'' = ''double.'' Likely because of this definition, many scientists use not only ''fold'' but also ''fold change'' to be synonymous with ''times'', as in ''3-fold larger'' = ''3 times larger.''. More ambiguous is fold decrease, where for instance a decrease of 50% between two measurements would generally be referred to a ''half-fold change'' rather than a ''2-fold decrease''.
