95 percent of measurements are less than 2 standard deviations away from the mean, assuming a normal distribution.
Z-Score.
My best estimate is around 1.5 standard deviations away from the norm.
To determine how many standard deviations away a value of 26 is from the mean of 16, subtract the mean from the value and then divide by the standard deviation. This calculation is as follows: ( (26 - 16) / 4 = 10 / 4 = 2.5 ). Therefore, a value of 26 is 2.5 standard deviations above the mean.

Standard deviation helps business understand the research they have done on their potential customers. If the information deviates by one, then they know that they can rely on the information more so than research that deviates to standards deviations away from the mean.
Z-Score tells how many standard deviations a measurement is away from the mean.

The answer depends on the individual measurement in question as well as the mean and standard deviation of the data set.
An IQ of 130 is considered "moderatley gifted." It's basically two standard deviations away from the norm (100).
