FORMULA MS-EXCEL PART-3

STATISTICAL FUNCTION 

1. MAX FUNCTION ()

Summary 

The Excel MAX function returns the largest numeric value in a range of values. The MAX function ignores empty cells, the logical values TRUE and FALSE, and text values.

Purpose 

Get the largest value

Return value 

The largest value in the array.

Syntax 

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

Arguments 

• number1 - Number, reference to numeric value, or range that contains numeric values.
• number2 - [optional] Number, reference to numeric value, or range that contains numeric values.

Usage notes 

The MAX function can be used to return the largest value from a set of data. For example, the slowest time in a race, the hightest temperature, or the top sales number. Arguments can be provided as constants, or as cell references or ranges, for example:

=MAX(5,10)
=MAX(A1,A2,A3)
-MAX(A1:A10)

2. MIN FUNCTION ()

Summary 

The Excel MIN function returns the smallest numeric value in a range of values. The MIN function ignores empty cells, the logical values TRUE and FALSE, and text values.

Purpose 

Get the smallest value.

Return value 

The smallest value in the array.

Syntax 

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

Arguments 

• number1 - Number, reference to numeric value, or range that contains numeric values.
• number2 - [optional] Number, reference to numeric value, or range that contains numeric values.

Usage notes 

The MIN function can be used to return the smallest value from a set of data. For example, the fastest time in a race, the lowest temperature, or the smallest sales number. Arguments can be provided as constants, or as cell references or ranges, for example:

=MIN(5,10)
=MIN(A1,A2,A3)
-MIN(A1:A10)

3.AVERAGE FUNCTION ()

Summary 

The Excel AVERAGE function returns the average of values supplied as multiple arguments. AVERAGE can handle up to 255 individual arguments, which can include numbers, cell references, ranges, arrays, and constants.

Purpose 

Get the average of a group of numbers

Return value 

A number representing the average.

Syntax 

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

Arguments 

• number1 - A number or cell reference that refers to numeric values.
• number2 - [optional] A number or cell reference that refers to numeric values.

Usage notes 

1. The AVERAGE function returns the average (arithmetic mean) of a group of supplied numbers.
2. To calculate the average, Excel adds the numbers together and divides by the total number of numbers. For example, AVERAGE (2,4,6) returns 4.
3. Numbers can be supplied as numbers, ranges, named ranges, or cell references that contain numeric values. Up to 255 numbers can be supplied.
4. The AVERAGE function will automatically ignore empty cells.

4.COUNT FUNCTION ()

Summary 

The Excel COUNT function returns the count of values that are numbers, generally cells that contain numbers. Values can be supplied as constants, cell references, or ranges.

Purpose 

Count numbers

Return value 

A number representing a count of numbers.

Syntax 

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

Arguments 

• value1 - An item, cell reference, or range.
• value2 - [optional] An item, cell reference, or range.

Usage notes 

The COUNT function counts the number of numbers in supplied values. Values can be items, cell references, or ranges. For example, =COUNT(1, 2, "apple") returns 2. And COUNT(A1:A10) will count the number of numeric values in the range A1:A10.

• Count can handle up to 255 additional values.
• Use COUNTA to include text and logical values. Use COUNTIF to count based on criteria.
• Error values or text values that cannot be coerced into numbers are not counted
• The logical values TRUE and FALSE are not counted.
• Empty cells and text are not counted

5. COUNTIF FUNCTION ()

Summary 

COUNTIF is a function to count cells that meet a single criteria. COUNTIF can be used to count cells with dates, numbers, and text that match specific criteria. The COUNTIF function supports logical operators (>,<,<>,=) and wildcards (*,?) for partial matching.

Purpose 

Count cells that match criteria

Return value 

A number representing cells counted.

Syntax 

=COUNTIF (range, criteria)

Arguments 

• range - The range of cells to count.
• criteria - The criteria that controls which cells should be counted.

Usage notes 

The COUNTIF function in Excel counts the number of cells in a range that match the supplied criteria

Non-numeric criteria needs to be enclosed in double quotes but numeric criteria does not:

=COUNTIF(A1:A10,100) // count cells equal to 100
=COUNTIF(A1:A10,">32") // count cells greater than 32
=COUNTIF(A1:A10,"jim") // count cells equal to "jim"
=COUNTIF(A1:A10,"<"&B1) // count cells less than value in B1

The wildcard characters ? and * can be used in criteria. A question mark matches any one character and an asterisk matches any sequence of characters.

To find a literal question mark or asterisk, use a tilde (~) in front question mark or asterisk (i.e. ~?, ~*).
