8. Jamelle performs three separate determinations of the density of a mineral sample. She gets values of 4.58 g/cm3, 4.79 g/cm3, and 4.55 g/cm3. a. Calculate the average value of the density of the mineral.
b. The deviation of a measured value is defined as the absolute value of the difference between the measured value and the average value: Deviation=|measured value−average value|. Calculate the deviation for each of the three measurements. According to the deviations, which measurement appears to be poorest compared to the others?
c. The average deviation is the sum of all the deviations divided by the total number of measurements. Calculate the average deviation of the three measurements.
d. When average deviation is high, does that indicate good precision or poor precision in the measurements? Explain.
