Please tell me if this is correct...Finding the mean, the average deviation from the mean, the standard deviation from the mean, and the relative deviation from the mean...of 10.1, 10.4 and 10.6
Mean-10.4
Average deviation-0.167
Standard deviation-0.25
Relative deviation-2%

Those look ok to me but I wonder why you rounded to 2% instead of 2.4% for RSD. You're allowed two places aren't you?

Yes, that does look better :)
