14 Worksheet 1: Definition of Terms Quiz203 Time: 10 minutes Instructions: Match each term (in the left column) with the appropriate definition item (in the right column). Write the letter of the appropriate definition in the space next to the term. Term Definition - 1. Accuracy A. Amount of scatter or variability around the mean, measured in units and percent - 2. Precision B . The average of our data or the best estimate of the true value produced by our laboratory 3. Imprecision C . The specific substance you are interested in measuring 4. Inherent Imprecision D. Difference between the average measured value (the mean) and the true value - 5 . Single Population of Data E. The closeness of agreement between results in a set of replicate measurements; typically expressed in terms of imprecision - 6. Mean F. Normal distribution of data that is symmetrical and clusters around the mean 7. Bias G. Quantifies the variation or dispersion of values measured in units - 8. Analyte (measurand) H. Closeness between the measured value for an analyte and the true value for that analyte - 9. Standard Deviation (SD) 1. Amount of imprecision encountered when the analytical system is stable due to slight changes in temperature, voltage, reagent or sample pipetting - 10 Gaussian Distribution J. Random points exhibiting a normal distribution with a specific mean and SD HILS1746 Effective Date: 12/6/2016
