Standard Deviation A measure of data spread around the mean. A low Standard Deviation in investment returns signifies stable performance. 12 Deviation The difference between a data point and the mean. The deviation of a test score from the class average shows individual performance relative to the...
Researchers and analysists operate on the standard deviation of a sample and population in different situations. For example, when summarizing the exam scores of a class of students, a teacher will use the population standard deviation. Statisticians calculating the national SAT average score would us...

The z score is a value calculated using a dataset's standard deviation. Z score measures how many standard deviations a value is above or below the mean. It's used to compare data with other data sets. It can be calculated using the formula z = (x - m)/s. ...
STDEV (*numeric*), also known as thecorrected standard deviation - where *numeric* is a fact or metric - Computes the sum of squared differences from the mean for *n* values divided by a sample size factor. If the input values are a sample of the total (biased) population, the divisor...
