Without measures, our day-to-day activities would be incomplete. Measurements necessitate the use of tools, both traditional and unorthodox, and different individuals may obtain different findings from the same instrument. As a result, measurements of a value can be either exact or accurate. The accuracy of any measured value relates to how near it is to the real value. Precision refers to how closely the different measured values are related.
The proximity of a value to its real value, such as the closeness of an arrow to the bull's eye in the center, is characterized as accuracy. That's the bull's eye: accurate is correct. The repeatability of the values of a measurement, such as the proximity of additional arrows to the first, is characterized as precise. Precise means striking the same area over and over, although that spot may not be the exact one.
Let's look at some examples to understand this better. 3.1459265359 is the value of pi. Now, 3.14 is a number that is used to symbolize the value of pi. It is not exact, but it is near. No other three-digit number comes close to the objective.
|The degree to which a value is accurate or truthful.||The precision with which the results acquired each time is calculated.|
|The degree to which the measured value is similar to a standard or genuine value.||The degree to which two or more measured values are similar.|
|Only one measurement||Several measurements|
|It must be exact for anything to be accurate constantly.||Precision is not the same as accuracy.|
In the following situations, determine if the measurements are accurate or precise:
Let's have a look at some key points about accurate versus precise:
