Across
  1. 3. measure of repeatability and reproducibility of a result
  2. 4. a measure of the systematic error; the difference between the average value and the true value; inversely related to trueness
  3. 5. the closeness of agreement between results of measurements performed under changed condition of measurements
  4. 8. the range of concentration over which the method is applicable without modification
  5. 9. frequency distribution graph that presents the number of times a given value occurs
  6. 12. the closeness of agreement between results of successive measurements carried out under the same conditions
  7. 13. the spread of data around the mean
  8. 14. the smallest results which can be distinguished from a suitable blank
  9. 15. indicates the extent of the variation or dispersion of the values about the mean expressed as a percentage; equals (SD / x̄) * 100; the ratio of the standard deviation to the mean; also known as relative standard deviation
  10. 17. most commonly occurring value in a set of numbers; the value at the peak of a frequency distribution curve
  11. 19. the ability of an analytical method to correctly measure pure analyte when added to the samples routinely analyzed
  12. 20. middle value in a set of numbers when the numbers are arranged in sequential order of increasing magnitude; the 50th percentile
Down
  1. 1. percentage of scores in the whole distribution that fall below the score that is being compared
  2. 2. a relative frequency distribution that forms a bell-shaped curve due to normal distribution in a set of values
  3. 6. measurements of reagent and sample constituent not including analyte
  4. 7. square root of the variance (measure of imprecision); measures dispersion of the variable about the mean
  5. 10. mathematical average of a group of numbers; set of data obtained by adding all the numbers in the set and dividing the sum by the number of values in that set
  6. 11. reflects dispersion around the mean and is the square of the standard deviation
  7. 16. a function that describes the relationship between instrument signal and concentration of analyte
  8. 18. the closeness of agreement of a single measurement with the true value; the extent to which a test result approximates the true value
