As the clinical chemistry supervisor, you are reviewing two analyzers. In order to compare the reproducibilities of these instruments, you run patient samples for glucose on each instrument. Using the following data, determine which instrument shows the greatest precision. Be sure to describe:
DATA
Instrument #1 Number of samples: 5 mean = 108 variance = 2.25
Instrument #2 Number of samples: 6 mean = 110 variance = 15.50
