## The IF Function with a single condition

IF Returns one value if a condition you specify evaluates to TRUE and another value if it evaluates to FALSE.

Use IF to conduct tests on values and formulas.

*Syntax
*

IF(logical_test,value_if_false)

A logical test is any value or expression that can be evaluated to TRUE or FALSE. For example, A10=100 is a logical expression: if the value in cell A10 is equal to 100, the expression evaluates to TRUE. Otherwise, the expression evaluates to FALSE.

**Arguments:
**

**1. Value_if_true** is the value that is returned if the logical test is TRUE.

**2. Value_if_false** is the value that is returned if the logical test is FALSE.

**Example:** Create the following worksheet.

Calculate the total cost paid by each customer given the condition that for the customer who bought 500 cartons and above they were charged 450 per carton others were charged 500. Find the total cost.

## NESTED IF STATEMENTS

A nested IF statement is an IF statement within another IF statement. You can write an IF statement with as many outcomes as you want.

*Syntax
*

=IF(CONDITION X, OUTPUT B, IF(CONDITION Y, OUTPUT C, OUTPUT D)))

In this structure, we have three outcomes with two conditions

We test IF condition X is false, we return output B

But if condition X is true, then we test condition Y

If condition Y is true, you have an output C and if it is false, you have output D

## Example: Three conditions and four outcomes

Using the **(Nested IF Formula**) find the **Grade** on condition that;-

Average |
Grade |

>=70 |
DISTINCTION |

>=60 |
CREDIT |

>=50 |
PASS |

<50 |
FAIL |

Type the first if statement

Put a comma, and type the next condition

Type another condition, value_if_true and value_if_false.

=IF(E2>=70,"DISTINCTION",IF(E2>=60,"CREDIT",IF(E2>50,"PASS","FAIL")))
