  • Significant Figures
    Digits in a measurement that reflect the precision of the value, including all certain digits plus one estimated digit.
  • Precision
    Degree to which repeated measurements under unchanged conditions show the same results, indicated by the number of reliable digits.
  • Measurement
    Process of obtaining a quantitative value for a property, where the number of reliable digits reflects its accuracy.
  • Uncertainty
    Range within which the true value is expected to lie, influenced by the number of reliable digits in a value.
  • Decimal Point
    Symbol used to separate the integer part from the fractional part of a number, affecting how reliable digits are counted.
  • Nonzero Number
    Any digit from 1 to 9, which determines where counting of reliable digits begins in a value.
  • Counting Rule
    Guideline for determining the number of reliable digits based on the presence or absence of a decimal point.
  • Left-to-Right Counting
    Method for determining reliable digits in values with a decimal, starting from the first nonzero digit.
  • Right-to-Left Counting
    Method for determining reliable digits in values without a decimal, starting from the first nonzero digit on the right.
  • Example
    Illustrative case used to clarify how to apply rules for determining the number of reliable digits in a value.
  • Recording
    Act of writing down measured values, where the number of reliable digits reflects the measurement's trustworthiness.
  • Value
    Numerical result obtained from a measurement, whose reliability is indicated by the number of significant digits.
