    +/- one standard deviation from the mean on a normal curve includes 68% of the population. Once you get past one SD from the mean you are firmly in the realm of abnormal, since you are either in the top or bottom 16% with said characteristic.

    Actually, according to my Probability and Stats class, if the data falls within two standard deviations, or within 95%, it is normal.

    What about a skewed curve?

    A one third occurance is not normal?

    I think Evan is correct.

    Ultimately, it's an arbitrary point where "normality" is defined.

    Using the method you described, color-blindness qualifies as "normal" since the colorblind population exceeds 5% of the total population. But color-blindness is something most people would consider an abnormality.

    But CC said it is defined in stat. Was he trying to hide a value judgement in math?

    Total color blindness is not 1/20. Partial (especially minor) color blindness is probably statistically significant (5%) and this normal.

    A normal curve is a two-tailed distribution. It's not a 1/3rd occurrence because the third encompasses polar opposites. It's actually two types of 1/6th occurrences.

    The part in bold makes absolutely no sense. What study are you referring to?

    Sure it is. If we take one SD, what is the percentage chance of a 'non-normal' occurence? 33%

    5% = statistically significant. Look it up. Don't confuse it with p-value.

    Choosing level of significance is a somewhat arbitrary task, but for many applications, a level of 5% is chosen, for no better reason than that it is conventional.
