  "term": "Chi-square test",
  "field": "Meteorology and atmospheric science",
  "definition": "A statistical hypothesis test used to determine if there is a statistically meaningful difference between observed frequencies and expected frequencies in one or more categories. In meteorology, it can be applied to assess the goodness of fit of a theoretical distribution to observed weather data, or to test for independence between two categorical variables, such as cloud type and precipitation occurrence. The test statistic follows a chi-square distribution.",
