Lesson 4

In Try This 2 you may have noticed that important measures don’t necessarily have a high precision. Keeping the engine temperature stable at approximately 93°C is more important than knowing the internal temperature of the car; but in this case, it had a lower precision.

Of the different measures, it is probably most important that the engine temperature have a high level of accuracy. If the temperature sensor is incorrect, the engine will run at the wrong temperature and this could damage the engine. If the internal or external temperatures are not accurate, it won’t significantly affect the functioning of the car.

As with the measurements in running a car, accuracy and precision are important in other applications.
