Chapter 1, Problem 1.90QP

Interpretation Introduction

Interpretation:

The given measurements are made for an object with a true volume $\text{17}\text{.55}\text{mL}$.  The measurements have to be described in terms of their accuracy and precision.

  $\text{18}\text{.69}\text{mL,}\text{18}\text{.69}\text{mL,}\text{18}\text{.70}\text{mL,}\text{18}\text{.71}\text{mL}$

Concept Introduction:

Accuracy:

The measurement of how close the measured value to the standard value is said to be accuracy.

Accuracy is measured in terms of error, the difference between true value and experimental value.

Precision:

Precision refers to how close two or more calculated values with each other.

It is represented by deviation, the variation that is present between two measured values.
