The following density measurements were made on a bar of iron: 7.58 g/mL, 8.02 g/mL, 7.83 g/mL, 7.80 g/mL, and 7.66 g/mL. The accepted value for iron's density is 7.85 g/ML. Find:
1) The average of this set of measurements 2) The average deviation of the set? 3) The relative average expressed as a percent?
For question 1 I got 7.778. For question 2 I got .126. I have no idea if these are right, and how to find the answer to number 3. Please explain your answers. Thank you!
