Question

what is the relationship between precision and uncertianity in a measurement?

Expert Solution

Step 1

Measurement Uncertainity has following parameters:

1) Precision : It given an idea about the variance of the estimates. If the variance of the estimates is low that means the result is precise.

2) Accuracy : It tells how close is the estimate from the actual values.

3) Bias : How human judgement is going to impacts the precision and accuracy.
