1. Record the weight you measured for the three trials of 100 μL:
Weight 1 (x₂)
Weight 2 (x₂) g
Weight 3 (x3)
10%
2. Average the three weights.
Average of three trials:
100g 13
3. Calculate the % error between the average of the three trials and the
true value:
avg weight - 0.100 g |
0.1g
4. Calculate the mean deviation for the three trials:
% Error =
X 100 = 0%
Mean deviation - Elx₁ = Xavel =
xavg
=
3
