IPA: /ˌlɒɡˈnɔːr.məl/
KK: /lɔgˈnɔrməl/
Describing a type of distribution in statistics where the logarithm of the variable follows a normal distribution.
The data showed a lognormal distribution, indicating that the logarithm of the values was normally distributed.
Lognormal → It is formed from 'log' (from logarithm, derived from the Greek 'logos', meaning ratio or proportion) and 'normal' (from Latin 'normalis', meaning conforming to a standard). The term 'lognormal' describes a distribution of a variable whose logarithm is normally distributed, indicating a relationship between logarithmic and normal distributions.
Think of 'log' as relating to ratios and 'normal' as conforming to a standard — together, they describe a distribution that behaves in a standard way when viewed on a logarithmic scale.
