AVERAGEIF

AVERAGEIF(range, criteria [,average_range])

Returns the arithmetic mean of all the numbers in a range that satisfies one condition.

range	The range of cells you want evaluated.
criteria	The expression that contains the criteria.
average_range	(Optional) The actual cells to average.

REMARKS

* AVERAGEIFS was added in Excel 2007 to replace this function.
* This function includes hidden cells.
* This function is not case sensitive when matching text strings.
* This function supports wildcards (? and *).
* Wildcard character: ? = a single character.
* Wildcard character: * = multiple characters.
* To include the actual wildcard characters prefix them with a tilde (~?) and (~*).
* This function uses the actual cell values and not the displayed formatted values.
* If "average_range" is left blank, then the cells in the "range" are used for both the criteria and the average.
* If no cells in "average_range" meet the criteria, then #DIV/0! is returned
* Arguments that are logical values are excluded.
* Arguments that are zero are included.
* Arguments that are text are excluded.
* If any cell references contain an error, then that error is returned.
* If any cell references are empty, then these are excluded.
* The "criteria" can contain wildcard characters.
* This is similar to the COUNTIF and SUMIF functions.

1 - What is the average of all the values in the range "B1:B5" which are greater than 28,000.
2 - What is the average of all the values in the range "C1:C5" which have 14,000 in the range "B1:B5".
3 - This is the same as 1 except the "criteria" uses a cell reference.
4 - This is the same as 1 except the "criteria" does not include an equal sign.
5 - This is the same as 1 except the "criteria" is not contained in speech marks.
6 - What is the average of all the values in the range "C1:C5" which have more than 14,000 in the range "B1:B5". (600 + 800 + 1000)
7 - This is the same as 5 except the "criteria" uses a cell reference.
8 - If the "sum_range" is left blank, then the "range" of cells is summed.
9 - What is the average of all the numbers in the range "B1:B4" that have (7000+14000+21000+28000)/10 in the range "B1:B4".
10 - What is the average of all the numbers in the range "B1:B5" that have a value greater than the average of the values in the range "B1:B5".
11 - What is the average of all the numbers in the range "C1:C5" that have the letter "o" in the range "E1:E5".
12 - What is the average of all the numbers in the range "C1:C5" that have the letter "h" in the range "E1:E5".
