Question

Triplicate samples of iron ore were titrated, and percentange iron was calculated. Is this an example of precision or accuracy in determining percentage iron in the ore? Explain your answer. Thank you!!

Answer 1

Before we answer wheather taking multiple readings (here triplicates of iron ores) improves accuracy or precision

First we need to understand the meaning of both accuracy and Precision

Accuracy tells us about the degree of closeness to the actual or true value

And

Precision is about closeness of readings or value to each other

Whenever we are taking multiple readings we take their average and hence the chances of us getting toward the actual or true value increase

Which is a sign of good accuracy

So the answer to this question is

This is examle of accuracy
