1.) Describe the proper way to use a meter stick and why this technique is necessary (include an explanation of uncertainty).

2.) What is the difference between percent error and standard error?

    1) There are some useful tips at

    2) Relative error is the absolute error, divided by the correct value.

    I do not know what you mean by "standard error"

  • Physics -

    For a definition of standard error, see
    http://davidmlane.com/hyperstat/A103397.html
    It is the random variation (standard deviation) in a series of measurements of the same thing, and is a measure of the typical absolute error in a measurement.
