Returns the average of the difference of a collection of numbers from their average (arithmetic mean). Returns the complementary ERF function integrated between a given lower bound and infinity. Returns a string formatted as a dollar amount from a given number. Get free icons of Standard deviation in iOS, Material, Windows and other design styles for web, mobile, and graphic design projects. If you don’t preserve the row or column references, if you move the formula (by cutting and pasting, or by adding new rows and columns), the references are adjusted relative to the formula’s new location. Returns the current system date. If the ByField normalization type is used, the normalization field should also be specified. μ and σ can take subscripts to show what you are taking the mean or standard deviation of. Returns a number rounded toward zero (rounded down) to the specified number of places. When precessing analysis statistics in Word, you might need to insert a mean symbol, which is ` x .
