WebNov 11, 2024 · Having a strong introduction to measurement, the next step in the bigger conversation about significant figures went much easier than in past years. If we can measure to a level of uncertainty, then we can apply the concepts to the calculations instead of just memorizing a set of rules. Reference. Unit 1 Worksheet 2: Read Scales. WebFor an analogue scale, the uncertainty is ± half of the smallest scale division. For a digital scale, the uncertainty is ± 1 in the least significant digit. Example of an analogue scale … Webof thumb for reading marked scales is that the uncertainty in a single measurement is half of the quantity between markings (in the previous example the quantity between markings is 1mL, so the uncertainty is 0.5 mL). However, there are other factors we must consider when deciding what a reasonable range of uncertainty is. the different types of variables
