Logical functions in Excel are crucial for decision-making and data analysis. Here are some commonly used and important logical functions:
1) IF: Performs a specified action based on a logical test.
Example: =IF(B2>35, "Pass", "Fail") returns "Pass" if B2 is greater than 35, otherwise, it returns "Fail".
2) AND: Returns TRUE if all conditions are met.
Example: =AND(B2>35, C2>35) returns 'TRUE' if both conditions are satisfied.
3) OR: Returns TRUE if at least one condition is met.
Example: =OR(A1>5, B1<10) returns TRUE if either condition is true.
4) NOT: Reverses the logical value of a statement.
Example: =NOT(B2>35) returns TRUE if B2 is not greater than 35.
5) IFERROR: Returns a value if a formula results in an error, and a different value if there's no error.
Example: =IFERROR(B2/C2, "Error") returns "Error" if there's a division by zero error.
6) IFS: Checks multiple conditions and returns a value corresponding to the first true condition.
Example: =IFS(A1>10, "High", A1>5, "Medium", TRUE, "Low") returns "High" if A1 is greater than 10, "Medium" if A1 is greater than 5, and "Low" otherwise.
These logical functions are essential for creating decision-based formulas and conducting various types of data analysis. They play a crucial role in automating tasks and making informed decisions in our day-to-day use of Excel.
