Examples

  • To ensure accurate results, the laboratory conducts a routine test of the normality of its sodium chloride solution.

  • In order to calculate the solution's concentration, we determined its normality based on the number of gram equivalents per liter.

  • However, in any case, it is desirable to be able to test for normality.

    Academic text (1992)
  • The normality of the data for each treatment was confirmed using normal scores plots.

    Academic text (2002)
  • Thus, scores were transformed to arcsine values to satisfy requirements for normality.

    Academic text (2005)
  • First, the normality of the dependent variable was tested: the assumption of normal distribution was not violated.

    Academic text (2005)
  • To test for multivariate normality, the Mahalanobis distances across the five dependent variables were calculated.

    Academic text (2010)
  • A normality check was undertaken for discrete variables to ensure distributions were not seriously skewed.

    Academic text (2008)
  • We first inspected the data for univariate normality and found that skewness and kurtosis for all measures were within 1.0.

    Academic text (2010)
  • Preliminary analyses were performed to ensure no violation of the assumptions of normality, linearity, and homoscedasticity.

Morphology

normality = normal (opaque) = normal + ity

Although formally 'normal' + '-ity', the chemical sense is a technical specialization (concentration in equivalents per liter) not inferable from the everyday meaning.

Etymology

Normality in chemistry comes from the same Latin norma, meaning a 'rule' or 'standard'. Chemists use normality as a fixed way to measure how concentrated a solution is, so the name reminds us it is a set 'rule' for measurement.
