Normal Curve Equivalent - Caution


Careful consideration is required when computing effect sizes using NCEs. NCEs differ from other scores, such as raw and scaled scores, in the magnitude of the effect sizes. Comparison of NCEs typically results in smaller effect sizes, and using the typical ranges for other effect sizes may result in interpretation errors.

Excel formula for conversion from Percentile to NCE:

=21.06*NORMSINV(PR/100)+50, where PR is the percentile value.

Excel formula for conversion from NCE to Percentile:

=100*NORMSDIST((NCE-50)/21.06), where NCE is the Normal Curve Equivalent (NCE) value

Famous quotes containing the word caution:

    People who wish to numb our caution in dealing with them by means of flattery are employing a dangerous expedient, like a sleeping draught, which, if it does not put us to sleep, keeps us all the more awake.
    Friedrich Nietzsche (1844–1900)

    “... Ain’t it a caution to us not to fix
    No limits to what rose in rubbing sticks
    On fire to scare away the pterodix
    When man first lived in caves along the creeks?”
    “Marvelous world in nineteen-twenty-six.”
    Robert Frost (1874–1963)

    Have I not walked without an upward look
    Of caution under stars....
    Robert Frost (1874–1963)
