WebNov 14, 2024 · The margin of uncertainty in a single reading is taken to be half the smallest increment on the measuring scale. This is because any reading should be rounded to the increments given on the scale. For example, if you measure the length of a pencil as 15cm to the nearest cm, the true length could be anywhere between 14.5 and 15.5cm. WebFor example, if a voltmeter we are using was calibrated incorrectly and reads 5% higher than it should, then every voltage reading we record using this meter will have an error of 5%. … WebJul 10, 2024 · If the child’s temperature reading was 37.0ºC (which is normal body temperature), the “true” temperature could be anywhere from a hypothermic 34.0ºC to a … shannon condee

WebApr 30, 2024 · Because parallax error is a type of random error, you can average multiple readings taken by different people to cancel out most of the parallax angle. It is likely that some readings will have positive parallax error and others will have negative error. The average of these readings will be closer to the true measurement.
