CLINICAL CHEMISTRY PART 2 QUESTIONS AND ANSWERS Measures of center - Answer-mean, median, mode The three most commonly used descriptions of the center of a dataset are the mean, the median, and the mode. Measures of spread - Answer-Coefficient of variation, Range, Standard deviation The spread represents the relationship of all the data points to the mean. There are three commonly used descriptions of spread: (1) range (2) standard deviation (SD), and (3) coecient of variation (CV). Sys...
