The data in the accompanying table represent the concentration of glucose in the blood serum of an adult patient. On four consecutive days, a blood sample was drawn from the patient and analyzed in triplicate. The variance for a given sample is an estimate of the measurement variance while the day-to-day variance reflects both the measurement variance and the sampling variance.
Day | Glucose | Concentration, | mg/100 Ml |
1 | 62 | 60 | 63 |
2 | 58 | 57 | 57 |
3 | 51 | 47 | 48 |
4 | 54 | 59 | 57 |
