Accuracy

In this mini-lesson, we shall explore the topic of accuracy, by finding answers to questions like what is meant by accuracy, what is the difference between accuracy and precision, and accuracy on the number line.

## Understanding Accuracy and Precision

Quite often we observe people taking a train to work and set their schedules based on the time of the trains. Let us assume that we have a daily train at a standard time of 7.00 AM. Observe the below timing of the train across two weeks.

 Timings 7:01 AM, 7:03AM, 7:00AM, 7:01AM, 7:03AM 7:02AM, 7:02AM, 7:02AM, 7:02AM, 7:02AM

For analyzing these above timings, the concepts of accuracy and precision are very helpful.

Let's move ahead and get to know more about accuracy and precision.

## What Is Meant by Accuracy?

Accuracy measures the closeness of the measurement to the actual value. Accuracy is a measure of the quality of measurement

In the process of purchase of a pound of bread from a supermarket, if the measured weight of 1 pound is equal to the printed weight of 1 pound, then we can call this measurement to be accurate. Accuracy is not directly calculated but can be calculated based on the errors. A measurement with low errors represents high accuracy.

Further, to understand more about the accuracy, let us look into the formulae for error calculations.
