★Answér:
Average length= (2.48 + 2.46 + 2.49 + 2.50 + 2.48)/5 =2.482.
Absolute error = 2.48 - 2.482 = |0.002|
2.46 - 2.482 = |0.022|
2.49 - 2.482 = |0.008|
2.50 - 2.482 = |0.018|
2.48 - 2.482 = |0.002|
% error = relative error*100 = mean absolute error / mean error
= [ (0.002) + (0.022) + (0.008) + (0.018) + (0.002) ] / 2.482
= (0.042) / 2.482 = 0.0169 (approx. value)
Now % error = 0.0169*100 = 1.69%.
