How measured value is reported in term of known and estimated digits?
Measured values are reported using significant figures, which include all known digits plus one estimated digit. The known digits are the reliable figures determined by the measurement instrument, while the estimated digit reflects the uncertainty in the measurement. For example, if a length is measured as 12.3 cm, the "12" are the known digits, and "3" is the estimated digit. This convention emphasizes the precision of the measurement and communicates the level of uncertainty inherent in the value.
When scientific measurements are made they are reported using all certain digits plus?
When scientific measurements are made, they are reported using all certain digits plus one estimated digit, which reflects the precision of the measurement. This practice helps convey the degree of uncertainty inherent in the measurement process. The last digit reported is typically the most uncertain and indicates the level of precision of the measuring instrument used. This convention ensures clarity and accuracy in scientific communication.

Do you round when using sig figs?
Yes, when using significant figures (sig figs), you round numbers to reflect the correct precision of the measurement. The final answer should not have more significant figures than the least precise measurement used in the calculation. Rounding is typically done based on the value of the digit immediately following the last significant figure.
Explain why significant figures represent the precision of a measurement and not its accuracy?
A measurement that has a larger number of significant figures has a greater reproducibility, or precision because it has a smaller source of error in the estimated digit. A value with a greater number of significant figures is not necessarily more accurate than a measured value with less significant figures, only more precise. For example, a measured value of 1.5422 m was obtained using a more precise measuring tool, while a value of 1.2 m was obtained using a less precise measuring tool. If the actual value of the measured object was 1.19 m, the measurement obtained from the less precise measuring tool would be more accurate.
How many numbers do you write when making a measurement?
If you are using a ruler, measure one digit more than the ruler reports. For instance, if you have a ruler that reports to the nearest millimeter, you will write your answer to the nearest tenth of a millimeter. (Estimate the last digit).
How do you indicate uncertainty in a measurement?
You can indicate uncertainty in a measurement by reporting the measurement value along with an estimated error margin or range. This can be expressed as a ± value or a range within which the true value is likely to fall with a certain level of confidence. Additionally, using significant figures to reflect the precision of the measurement can also convey uncertainty.

Approximated measurement based on previous experience is?
An estimated measurement based on past knowledge or familiarity with a similar situation. It can help provide a rough idea or guess of the quantity or size of something without using precise measurements or tools.
