Accuracy
Accuracy is simply how close a measurement is to the true or accepted value.
For example, if we design an experiment to measure the boiling point of water, and we get a result of 100.5°C, that measurement is quite accurate because it’s very close to the true value of 100°C. But if we get a result of 90°C, that measurement is not very accurate because it’s very far from the true value.

|---|---|
| What is accuracy? | A measurement of how close a value is to the true or accepted value. For example: measuring the boiling point of water as 100.5°C is accurate; 90°C is not. |
| In the example, why is 100.5°C considered an accurate measurement of waters boiling point? | It is very close to the true/accepted value of 100°C. |
| In the example, why is 90°C considered an inaccurate measurement of waters boiling point? | It is far from the true/accepted value of 100°C. |
