Get the largest value
Return value 
The largest value in the array.
Syntax 
=MAX (number1, [number2], ...)
Arguments

  • 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 ()

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.

  • 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.

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. ~?, ~*).
