Question

the temperature outside is 75.0°f, but four students got different measurements when using thermometers. classify the data as accurate, precise, both or neither. 77.5°f 77.9°f 77.5°f 77.1°f answer:

Explanation:

Step1: Understand accuracy and precision

Accuracy is how close a measurement is to the true value. Precision is how close the measurements are to each other.
The true value is \(75.0^{\circ}F\). The measurements are \(77.5^{\circ}F\), \(77.9^{\circ}F\), \(77.5^{\circ}F\), \(77.1^{\circ}F\)

Step2: Check accuracy

The measurements (\(77.1 - 77.9\)) are not close to the true value of \(75.0\). So not accurate.

Step3: Check precision

The measurements \(77.1\), \(77.5\), \(77.5\), \(77.9\) are close to each other (differ by at most \(0.8\)). So precise.

Answer:

Precise
