HSN.Q.A.3: Choose a level of accuracy appropriate to limitations on measurement when reporting quantities.
What you'll learn
- Distinguish between accuracy and precision in measurement contexts, and explain how each can fail independently
- Identify the number of significant figures in a reported measurement and explain what that number signals about the measurement's precision
- Apply significant-figure rules correctly when reporting the result of a calculation involving measured values
- Match the reported precision of a quantity to the resolution of the measuring instrument and the practical demands of the context
- Recognize when a reported quantity has false precision (too many digits) or inappropriate under-precision (too few digits) for the situation
