Microsoft® Excel® Statistical Functions

Syntax:

=AVERAGE(number1, [number2],...)

Arguments:

•number1 RequiredThe first number, cell reference, or range for which you want the average.

•number2, ... OptionalAdditional numbers, cell references or ranges for which you want the average, up to a maximum of 255.


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.

QUIZ Question

A)StatisticalB)LookupC)MathematicalD)Basic

QUIZ Question

The AVERAGE function is in what category of functions:

A)Statistical B)LookupC)MathematicalD)Basic


Syntax:

=COUNT(value1, [value2],...)

Arguments:

•value1 RequiredThe first item, cell reference, or range within which you want to count numbers.

•value2, ... OptionalUp to 255 additional items, cell references, or ranges within which you want to count numbers.


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

QUIZ Question

The COUNT function is in what category of functions:

A)LogicalB)InformationC)StatisticalD)Mathematical

QUIZ Question

The COUNT function is in what category of functions:

A)LogicalB)InformationC)Statistical D)Mathematical


Syntax:

=COUNTA(value1, [value2],...)

Arguments:

•value1 RequiredThe first argument representing the values that you want to count.

•value2, ... OptionalAdditional arguments representing the values that you want to count, up to a maximum of 255 arguments.


Description:

•Counts the number of cells that are not empty in a range.

Remarks:

•Counts cells containing any type of information, including error values and empty text ("“).•The COUNTA function does not count empty cells.

Errors:

None


=COUNTA(A2:A8)


=COUNTA(A2:A8)=6

QUIZ Question

The major difference between the COUNT and COUNTA functions is that the COUNTA function will count empty cells as well as numerical, text, and empty text values.

A)TrueB)False


Syntax:

=MAX(number1,[number2],...)

Arguments:

•number1, number2, ... Required1 to 255 numbers for which you want to find the maximum value.


Description:

•Returns the largest value in a set of values.

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:



Syntax:

=MEDIAN(number1, number2, …)

Arguments:

•number1 Required1 to 255 numbers for which you want the median.

number2, … Optional1 to 255 numbers for which you want the median.


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.


=MEDIAN(A1:A5)


=MEDIAN(A1:A5)=3


=MEDIAN(A1:A6)


=MEDIAN(A1:A6)=3.5


Syntax:

=MIN(number1,[number2],...)

Arguments:

•number1, number2, ... Required1 to 255 numbers for which you want to find the minimum value.


Description:

•Returns the smallest value in a set of values.

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, MIN returns 0 (zero).

Errors:


Microsoft® Excel® Mathematical Functions

Syntax:

=SUM(number1, [number2], [number3], [number4], ...)

Arguments:

•number1 RequiredThe first item that you want to add.

•number2, number3, number4, ... OptionalThe remaining items that you want to add, up to a total of 255 items.


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.
