1. absorption coefficient a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber
  2. correlation coefficient a statistic representing how closely two variables co-vary
  3. absorption unit a unit for measuring absorption
  4. absorbefacient inducing or promoting absorption
  5. absorption band a dark band in the spectrum of white light that has been transmitted through a substance that exhibits absorption at selective wavelengths
  6. regression coefficient when the regression line is linear (y = ax + b) the regression coefficient is the constant (a) that represents the rate of change of one variable (y) as a function of changes in the other (x); it is the slope of the regression line
  7. absorption factor (physics) the property of a body that determines the fraction of the incident radiation or sound flux absorbed or absorbable by the body
  8. biserial correlation coefficient a correlation coefficient in which one variable is many-valued and the other is dichotomous
  9. differential coefficient the result of mathematical differentiation
  10. absorption indicator an indicator used in reactions that involve precipitation
  11. multiple correlation coefficient an estimate of the combined influence of two or more variables on the observed (dependent) variable
  12. abortifacient causing abortion
  13. probation officer the officer of the court who supervises probationers
  14. absorption spectrum the spectrum of electromagnetic radiation that has passed through a medium that absorbed radiation of certain wavelengths
  15. observation station a station set up for making observations of something
  16. observation post an elevated post affording a wide view
  17. tetrachoric correlation coefficient a correlation coefficient computed for two normally distributed variables that are both expressed as a dichotomy
  18. drag coefficient the ratio of the drag on a body moving through air to the product of the velocity and the surface area of the body
  19. sorbefacient inducing or promoting absorption
  20. absorptance a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber
