© 2011 REACH-CRC. All Rights Reserved. Microsoft ® Excel ® Mathematical Functions Syntax: =SUM(number1, [number2], [number3], [number4],...) Arguments: number1 Required  The first item that you want to add. number2, number3, number4,... Optional  The remaining items that you want to add, up to a total of 255 items.

© 2011 REACH-CRC. All Rights Reserved. Microsoft ® Excel ® Mathematical Functions Description: Adds all the numbers that you specify as arguments. Remarks: Each argument can be a range, a cell reference, an array, a constant, a formula, or the result from another function. If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, or text in the array or reference are ignored. Errors: If any arguments are error values, or if any arguments are text that cannot be translated into numbers, Excel displays an error.

© 2011 REACH-CRC. All Rights Reserved. Microsoft ® Excel ® Statistical Functions Description: Returns the average (arithmetic mean) of the arguments. Remarks: Arguments can either be numbers or names, ranges, or cell references that contain numbers. Logical values and text representations of numbers that you type directly into the list of arguments are counted. If a range or cell reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included. Errors: Arguments that are error values or text that cannot be translated into numbers cause errors.

Arguments: value1 Required  The first item, cell reference, or range within which you want to count numbers. value2,... Optional  Up to 255 additional items, cell references, or ranges within which you want to count numbers.

© 2011 REACH-CRC. All Rights Reserved. Microsoft ® Excel ® Statistical Functions Description: Counts the number of cells that contain numbers, and counts numbers within the list of arguments. Remarks: Arguments that are numbers, dates, or a text representation of numbers (for example, a number enclosed in quotation marks, such as "1") are counted. Logical values and text representations of numbers that you type directly into the list of arguments are counted. Arguments that are error values or text that cannot be translated into numbers are not counted. If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, text, or error values in the array or reference are not counted. Errors: None

© 2011 REACH-CRC. All Rights Reserved. Microsoft ® Excel ® Statistical Functions Syntax: =MEDIAN(number1, number2, …) Arguments: number1 Required  1 to 255 numbers for which you want the median.  number2, … Optional  1 to 255 numbers for which you want the median.

© 2011 REACH-CRC. All Rights Reserved. Microsoft ® Excel ® Statistical Functions Description: Returns the median of the given numbers. Remarks: The median is the number in the middle of a set of numbers. If there is an even number of numbers in the set, then MEDIAN calculates the average of the two numbers in the middle. Arguments can either be numbers or names, arrays, or references that contain numbers. Logical values and text representations of numbers that you type directly into the list of arguments are counted. If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included. Errors: Arguments that are error values or text that cannot be translated into numbers cause errors.

Remarks: Arguments can either be numbers or names, arrays, or references that contain numbers. Logical values and text representations of numbers that you type directly into the list of arguments are counted. If an argument is an array or reference, only numbers in that array or reference are used. Empty cells, logical values, or text in the array or reference are ignored. If the arguments contain no numbers, MAX returns 0 (zero). Errors: Arguments that are error values or text that cannot be translated into numbers cause errors.
