  "id": "MLC-T-CHM-006757",
  "term": "Log-normal transformation",
  "field": "Chemistry",
  "definition": "A mathematical procedure applied to data that are not normally distributed, involving taking the logarithm of each data point. This transformation often converts skewed data, particularly those with a positive skew, into a more symmetrical, approximately normal distribution. It is frequently used in statistical analysis to meet the assumptions of parametric tests, such as ANOVA or regression.",
