COUNT FUNCTIONS

COUNT Function:
The COUNT function counts the number of cells that contain numbers, and counts numbers within the list of arguments. Use the COUNT function to get the number of entries in a number field that is in a range or array of numbers.

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

The COUNT function syntax has the following arguments:
value1    Required. The first item, cell reference, or range within which you want to count numbers.
value2, ...    Optional. Up to 255 additional items, cell references, or ranges within which you want to count numbers.
 
Note: The arguments can contain or refer to a variety of different types of data, but only numbers are counted.
 
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.
 
Q:
How to count the cells that they are contained only numbers in the selected range?
Type the function as follows in the cell that you would like to get the result in:
=COUNT(A1:F16)

COUNTA Function:
I have given the formula syntax and usage of the COUNTA function in Microsoft Excel.
 
Description:
The COUNTA function counts the number of cells that are not empty in a range.
 
Syntax:
COUNTA(value1, [value2], ...)
 
The COUNTA function syntax has the following arguments:
value1    Required. The first argument representing the values that you want to count.
value2, ...    Optional. Additional arguments representing the values that you want to count, up to a maximum of 255 arguments.
 
Remarks:
The COUNTA function counts cells containing any type of information, including error values and empty text (""). For example, if the range contains a formula that returns an empty string, the COUNTA function counts that value. The COUNTA function does not count empty cells.
 
Q:
How to count the cells containing any type of information in selected range?
Type the function as follows in the cell that you would like to get the result in:
=COUNTA(A1:F16)

COUNTBLANK function:
Use the COUNTBLANK function, one of the Statistical functions, to count the number of empty cells in a range of cells.
 
Syntax:
COUNTBLANK(range)
 
The COUNTBLANK function syntax has the following arguments:
Range    Required. The range from which you want to count the blank cells.
 
Remark:
Cells with formulas that return "" (empty text) are also counted. Cells with zero values are not counted.
 
Q:
How to count blank cells in the selected range?
Type the function as follows in the cell that you would like to get the result in:
=COUNTBLANK(A1:F16)

COUNTIF function:
Use COUNTIF, one of the statistical functions, to count the number of cells that meet a criterion; for example, to count the number of times a particular name of location appears in damage parts list of a company product.
 
In its simplest form, COUNTIF says:
=COUNTIF(Where do you want to look?, What do you want to look for?)
 
Syntax:
COUNTA(range, criteria)
 
Remark:
The COUNTIF function counts the number of cells that contain particular text in order to criteria and return the values for total of text within the list of arguments.
 
Q:
How to count particular cells that contain “>75” within the selected range?
Type the function as follows in the cell that you would like to get the result in:
=COUNTIF(C3:C13,”>75”)
=COUNTIF(C3:C13,”TL3”) This example for, when you need to use COUNTIF to count number of times a particular text in the list.

COUNTIFS function:
The COUNTIFS function applies criteria to cells across multiple ranges and counts the number of times all criteria are met.
 
Syntax:
COUNTIFS(criteria_range1, criteria1, [criteria_range2, criteria2]…)
The COUNTIFS function syntax has the following arguments:
criteria_range1    Required. The first range in which to evaluate the associated criteria.
 
criteria1    Required. The criteria in the form of a number, expression, cell reference, or text that define which cells will be counted. For example, criteria can be expressed as 32, ">32", B4, "apples", or "32".
 
criteria_range2, criteria2, ...    Optional. Additional ranges and their associated criteria. Up to 127 range/criteria pairs are allowed.
 
Important: Each additional range must have the same number of rows and columns as the criteria_range1 argument. The ranges do not have to be adjacent to each other.
 
Remarks:
Each range’s criteria is applied one cell at a time. If all of the first cells meet their associated criteria, the count increases by 1. If all of the second cells meet their associated criteria, the count increases by 1 again, and so on until all of the cells are evaluated.
 
Q:
How to count the students that they are how many of them have passed in both subjects with over 64 in maths and over 74 in science?
OR
How to count, how many students have marks(maths) that are greater than or equal to 65 in cells B3 through B13, and also have marks(science) that are greater than 75 in cells C3 through C13?
Type the function as follows in the cell that you would like to get the result in:
=COUNTIFS(B3:B13, ”>=65”, C3:C13, “>=75”)
