Digits in a measurement that include all known values plus one estimated digit, reflecting the precision of the measurement. Precision
The degree to which repeated measurements under unchanged conditions show the same results, indicated by the number of significant figures. Measurement
A value obtained using instruments, consisting of all certain digits and one estimated digit to reflect accuracy. Decimal Point
A symbol used to separate the whole number part from the fractional part, affecting how significant figures are counted. Nonzero Number
Any digit from 1 to 9, always considered significant when counting significant figures in a value. Estimate
An additional digit added to a measurement based on judgment, representing uncertainty beyond the smallest marked unit. Hash Mark
A line or marking on a measuring tool indicating a specific value or interval for reading measurements. Uncertainty
The doubt associated with the last digit of a measurement, arising from limitations of the measuring instrument. Known Number
A digit in a measurement that is certain and directly read from the measuring instrument. Eyeball Test
A method of estimating one additional digit beyond the smallest marked unit when reading a measurement. Data Analysis
The process of interpreting measurements, where the number of significant figures impacts the reliability of conclusions. Beaker
A common laboratory container with volume markings, used for measuring liquids and applying significant figures. Measuring Tape
A flexible tool marked with units, used to determine length and apply the rules of significant figures. Detail
The amount of information conveyed by a measurement, increased by including more significant figures.
