Excel Formula Construction

Formula Translation

User's Requirement

The user intends to create a formula that checks if the value in cell B31 is greater than or equal to the value in B17 and less than or equal to the value in B20.

Corrected Formula

The provided formula contains incorrect syntax. The correct formula to achieve this logic in Excel is:

=IF(AND(B31 >= B17, B31 <= B20), "YES", "NO")

Explanation of the Formula

Components Breakdown

• IF Function: This function evaluates a condition and returns one value if true and another value if false.

  • Syntax: IF(logical_test, value_if_true, value_if_false)

• AND Function: This function checks multiple conditions and returns TRUE only if all conditions are true.

  • Syntax: AND(condition1, condition2, ...)

Logic Flow

1. Logical Test: AND(B31 >= B17, B31 <= B20)
   • This checks if B31 is greater than or equal to B17 and less than or equal to B20.
2. Return Value:
   • If the conditions are met (result is TRUE), it returns "YES".
   • If the conditions are not met (result is FALSE), it returns "NO".

Practical Illustration

Example Scenario

Assume the following values in cells:

• B17: 10
• B20: 20
• B31: 15

Applying the Formula

Cell where the formula is entered (for example, B32):

• Enter: =IF(AND(B31 >= B17, B31 <= B20), "YES", "NO")

Evaluation

• Condition Check:
  • 15 (B31) >= 10 (B17) → TRUE
  • 15 (B31) <= 20 (B20) → TRUE
• Since both conditions are TRUE, the formula will return "YES".

Summary

The formulated Excel equation accurately evaluates the specified condition regarding the values in cells B31, B17, and B20, yielding a direct output of "YES" or "NO" based on the conditions specified. This mechanism provides a reliable method for condition-based assessments within datasets.
