    result from unknown or unpredictable variations in experimental situations.

    Random errors

  • 2

    They are also referred to as accidental errors and are sometimes beyond the control of the observer.

    Random errors

  • 3

    _ are associated with particular measuring instruments or techniques such as an improperly calibrated instrument or bias on the part of the part of the observer.

    Systematic errors

  • 4

    Is used for measurement done with several trials.

    Mean Absolute deviation

  • 5

    the best approximation of the measured quantity –this can be a direct reading from the measuring device or an average value of several readings

    x^-

  • 6

    the degree of error or error estimate associated with the measurement

    ±∆x

  • 7

    degree of confidence one has in a measurement.

    precision of the measurement

  • 8

    expresses high confidence that the measurement lies within a narrow range of values expressed by ∆x

    high precision

  • 9

    lies within a wider range of values

    low precision

  • 10

    High precision means

  • 11

    Low precision means

    high ∆x

  • 12

    Random error can be minimized by

    repeating the measurements sufficient number of times.

  • 13

    determined by simply averaging the absolute value of the difference (or deviation) of each of the measured values from the mean.

    mean absolute deviation

  • 14
