In a measurement, if the uncertainty is ±0.1 g, what does it indicate? (2023)

In a measurement, if the uncertainty is ±0.1 g, what does it indicate? (2023)

Step 1: Understand what a measurement is. A measurement is a value that tells you how much of something there is, like weight.
Step 2: Know what uncertainty means. Uncertainty tells you how much the measurement could be off or different from the actual value.
Step 3: Look at the uncertainty given, which is ±0.1 g. This means the measurement could be 0.1 grams more or 0.1 grams less than the reported value.
Step 4: If the reported measurement is, for example, 5.0 g, the actual weight could be as low as 4.9 g or as high as 5.1 g.
Step 5: Conclude that the uncertainty helps you understand the range of possible values for the measurement.
