Excel STDEV.S Function

Excel STDEV.S Function Purpose Return value Syntax Arguments Get the standard deviation in a sample Return value  Estimated standard deviation Syntax  =STDEV.S (number1, [number2], ...) Arguments  number1 - First number or reference in the sample. number2 - [optional] Second number or reference. Usage notes  The STDEV.S function calculates the standard deviation in a sample set of data. Note: STDEV.S replaces the older STDEV function, but has identical behavior. Although STDEV still exists for backwards compatibility, Microsoft recommends that people use the newer STDEV.S function instead. www.prolearninghub.com

Excel STDEV.S Function Notes: STDEV.S calculates standard deviation using the "n-1" method. STDEV.S assumes your data is a sample only. When your data is complete (i.e. when your data representations the entire population), calculate standard deviation using the STDEVP.P function. Numbers are supplied as arguments. They can be supplied as actual numbers, ranges, arrays, or references that contain numbers. The STDEV.S function will include numbers entered as text and logical values when they are entered directly as arguments. However, when an argument is an array or reference, empty cells, logical values, text, and error values are ignored. When you want to include logical values and/or numbers as text in a reference, use the STDEVA function. www.prolearninghub.com

Excel STDEVP Function

Excel STDEVP Function Purpose Get standard deviation of population Return value  Estimated standard deviation Syntax  =STDEVP (number1, [number2], ...) Arguments  number1 - First number or reference in the sample. number2 - [optional] Second number or reference. Usage notes  The STDEVP function calculates the standard deviation in a sample set of data. Standard deviation is a measure of how much variance there is in a set of numbers compared to the average (mean) of the numbers. Note: STDEVP has been replaced with a newer function called STDEV.P, which has identical behavior. Although STDEVP still exists for backwards compatibility, Microsoft recommends that people use the newer STDEV.P function instead. www.prolearninghub.com

Excel STDEVP Function Notes: STDEVP calculates standard deviation using the "n" method, ignoring logical values and text. STDEVP assumes your data is the entire population. When your data is a sample set only, calculate standard deviation using the STDEV function (or it's more current replacement, the STDEV.S function). Numbers are supplied as arguments. They can be supplied as actual numbers, ranges, arrays, or references that contain numbers. The STDEVP function ignores logical values and text. If  you want to include logical values and/or numbers as text in a reference, use the STDEVA function. www.prolearninghub.com

Excel CHAR Function

Excel CHAR Function Purpose Return value Syntax Arguments Usage notes Get a character from a number Return value  A single character specified by a number. Syntax  =CHAR (number) Arguments  number - A number between 1 and 255. Usage notes  Use CHAR to translate code page numbers into actual characters. CHAR can be useful when you want to specify characters in formulas or functions that are awkward or impossible to type directly. For example, you can use CHAR(10) to add a line break in a formula on Windows, and CHAR(13) to add a line break on the Mac. The character returned is based on the character set used by your computer: http://en.wikipedia.org/wiki/Windows-1252 - Windows http://en.wikipedia.org/wiki/Mac_OS_Roman - Mac www.prolearninghub.com

Unicode contains other non-printable characters that are not removed. www.prolearninghub.com

Excel CONCATENATE Function

Excel CONCATENATE Function Purpose  Join text together Return value  Text joined together. Syntax  =CONCATENATE (text1, text2, [text3], ...) Arguments  text1 - The first text value to join together. text2 - The seond text value to join together. text3 - [optional] The third text value to join together. www.prolearninghub.com

Excel CONCATENATE Function Usage notes  CONCATENATE can join up to 30 text items together. Text items can be text strings, numbers, or cell references that refer to one cell. Numbers are converted to text when joined. If you need to specify a number format for a number being joined, see the TEXT function. The ampersand character (&) is an alternative to CONCATENATE. The result is the same, but the ampersand is more flexible, and creates formulas that are shorter and (arguably) easier to read. www.prolearninghub.com

Excel Dollar Function

Excel DOLLAR Function Purpose Return value Arguments Usage notes Convert a number to text in currency format Return value  A number as text in currency format. Syntax =DOLLAR (number, decimals) Arguments  number - The number to convert. decimals - The number of digits to the right of the decimal point. Default is 2. Usage notes  The DOLLAR function converts a number to text using currency number format. The number format used is $#,##0.00_);($#,##0.00). The default for decimals is 2. If decimals is negative, number will be rounded to the left of the decimal point. The TEXT function is a more flexible way to achieve the same result, since it can convert numbers to text in currency format and other number formats as well. The name of the function and the currency symbol used is based on language settings of the computer. www.prolearninghub.com
