Problem
Hematology dept is currently evaluating between 3 hematology anlayzer (CBCNao, Diffstat, and HeMore) to run a CBC count and differential. Assessing the analytical parameters involved in Hgb measurements.
Given: 3.9, 3.2, 4.5, 3.2, 4.3, 49, 3.9, 4.6, 3.8, 3.7, 3.8, 5.2, 4.1, 5.1, 4.1, 3.8, 4.3, 4.5, 3.9, 4.5, 4.3, 4.6, 4.8, 4.2, 3.8
Determine the mean, Standard Deviation, and coefficient of variation to 1 decimal place (0.0)
Mean (x, g/dL), Standard deviation (SD, g/dL), Coefficient of variation (CV).
Show me how to calculate this and then if 2 instruments had Hgb of 3.532 g/dL and anothr at 5.113 g/dL which would be more precise?
