IFS Function Correction and Usage in Excel

This guide provides a corrected version of an Excel formula using the IFS function to categorize values in specific ranges, along with an explanation of its structure, logic, and practical examples for effective data analysis.

Prompt

=IFS(I14<= 144,1,AND(I14=>144,I14< 288),2,AND(I14>=288,I14< 432),3,AND(I14>=432,I14< 576,4,AND(I14>=576,I14< 720),5,AND(I14>=720,I14< 864),6,AND(I14>= 864,I14< 1008),7,AND(I14>= 1008,I14< 1152), 8,AND(I14>=1152,I14< 1296),9,AND(I14>=1296,I14< 1440),10)

Answer

Excel Formula Translation and Explanation

Formula Translation

The provided formula has a few issues, particularly in the syntax for the logical conditions and the structure of the IFS function. The correct translation of the logic using the IFS function in Excel is as follows:

=IFS(
    I14 < 144, 1,
    I14 >= 144, I14 < 288, 2,
    I14 >= 288, I14 < 432, 3,
    I14 >= 432, I14 < 576, 4,
    I14 >= 576, I14 < 720, 5,
    I14 >= 720, I14 < 864, 6,
    I14 >= 864, I14 < 1008, 7,
    I14 >= 1008, I14 < 1152, 8,
    I14 >= 1152, I14 < 1296, 9,
    I14 >= 1296, I14 < 1440, 10
)

Key Corrections Made:

The logical operator for "greater than or equal to" is >=, not =>.
The AND function isn't necessary when used with IFS and can lead to syntax errors.
Conditions are formatted using separate arguments in the IFS function.

Formula Explanation

Structure of the Formula

IFS Function: This function evaluates multiple conditions and returns a corresponding value for the first true condition.
Conditions and Values: Each pair of arguments consists of a condition followed by the value to return if that condition is true.

Logic

If I14 is less than 144, return 1.
If I14 is between 144 and 288, return 2.
If I14 is between 288 and 432, return 3.
The pattern continues up to 1440, with corresponding return values from 1 to 10.

Application Scope

This formula is useful in scenarios where you need to categorize values based on specified ranges. This is particularly applicable in performance metrics, grading systems, or any quantitative analysis requiring categorization.

Practical Example

Assuming you have the following values in cell I14:

I14 Value	Result
130	1
160	2
300	3
500	4
700	5
900	6
1100	8
1300	9

According to the formula:

If I14 is 130, it returns 1 since 130 is less than 144.
For I14 with a value of 160, it returns 2, which falls in the range of 144 to 288.
The same logic applies to other values based on the stated conditions.
