IF function in Excel - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the IF function do in Excel?

The IF function checks if a condition is true or false. It returns one value if true, and another if false.

beginner

Write the basic syntax of the IF function.

The syntax is: =IF(condition, value_if_true, value_if_false).

beginner

How would you use IF to check if a number in cell A1 is greater than 10?

Use =IF(A1>10, "Yes", "No"). It shows "Yes" if A1 is more than 10, otherwise "No".

beginner

Can the IF function return text values? Give an example.

Yes. Example: =IF(B1="Pass", "Well done", "Try again") returns text based on B1's value.

intermediate

What happens if the condition in IF is false and you leave value_if_false empty?

Excel returns FALSE by default if value_if_false is missing.

What will =IF(5 > 3, "Yes", "No") return?

A 3

B "No"

C "Yes"

D 5

5 is greater than 3, so the condition is true and the function returns "Yes".

Which part of IF function is the condition to check?

A condition

B value_if_false

C value_if_true

D result

The first part inside IF is the condition that Excel tests.

What does =IF(A1=10, 100, 0) do?

A Returns 10 if A1 equals 100, else 0

B Returns 100 if A1 equals 10, else 0

C Returns 0 if A1 equals 10, else 100

D Always returns 100

It checks if A1 is 10; if yes, returns 100; otherwise returns 0.

Can IF function be used to return numbers?

A Yes, it can return numbers or text

B Only logical TRUE or FALSE

C No, only text

D Only dates

IF can return any value, including numbers, text, or logical values.

What will =IF(FALSE, "Yes", "No") return?

A "Yes"

B FALSE

C TRUE

D "No"

Since the condition is FALSE, IF returns the value_if_false, which is "No".

Explain how the IF function works in Excel with an example.

Think about checking if a number is bigger than another.

Describe a real-life situation where you could use the IF function in a spreadsheet.

Consider grading students or checking sales targets.

Practice

1. What does the Excel formula =IF(A1>10, "Yes", "No") do?

easy

A. It checks if the value in A1 is greater than 10 and returns "Yes" if true, otherwise "No".

B. It adds 10 to the value in A1 and returns "Yes" or "No".

C. It always returns "Yes" regardless of A1's value.

D. It checks if A1 equals 10 and returns "Yes" or "No".

Solution

1. Step 1: Understand the IF function structure

   The IF function checks a condition first, here if A1>10.

2. Step 2: Determine the output based on the condition

   If the condition is true, it returns "Yes"; if false, it returns "No".

3. Final Answer:

   It checks if the value in A1 is greater than 10 and returns "Yes" if true, otherwise "No". -> Option A

4. Quick Check:

   IF(condition, true_result, false_result) = It checks if the value in A1 is greater than 10 and returns "Yes" if true, otherwise "No". [OK]

Hint: Remember: IF(condition, value_if_true, value_if_false) [OK]

Common Mistakes:

• Confusing the order of true and false results
• Thinking IF adds or changes values
• Assuming it always returns true result

2. Which of the following is the correct syntax for the IF function in Excel?

easy

A. =IF(condition; value_if_true; value_if_false)

B. =IF(condition value_if_true value_if_false)

C. =IF condition, value_if_true, value_if_false

D. =IF(condition, value_if_true, value_if_false)

Solution

1. Step 1: Recall Excel formula syntax

   Excel formulas use commas to separate arguments, not semicolons or spaces.

2. Step 2: Identify the correct syntax

   The correct syntax is =IF(condition, value_if_true, value_if_false).

3. Final Answer:

   =IF(condition, value_if_true, value_if_false) -> Option D

4. Quick Check:

   Arguments separated by commas = =IF(condition, value_if_true, value_if_false) [OK]

Hint: Use commas to separate IF arguments, not semicolons or spaces [OK]

Common Mistakes:

• Using semicolons instead of commas
• Omitting parentheses
• Not separating arguments properly

3. Given the formula =IF(B2<50, "Fail", "Pass") and the value in B2 is 45, what will be the result?

medium

A. Fail

B. Pass

C. 45

D. Error

Solution

1. Step 1: Evaluate the condition B2<50 with B2=45

   Since 45 is less than 50, the condition is true.

2. Step 2: Determine the IF function output

   Because the condition is true, the formula returns "Fail".

3. Final Answer:

   Fail -> Option A

4. Quick Check:

   Condition true returns first value = Fail [OK]

Hint: Check condition result first, then pick true or false output [OK]

Common Mistakes:

• Choosing the false result instead of true
• Returning the cell value instead of text
• Confusing less than and greater than

4. Identify the error in this formula: =IF(A1>100 "High" "Low")

medium

A. Wrong comparison operator

B. Missing commas between arguments

C. Extra parentheses

D. Incorrect use of quotes

Solution

1. Step 1: Check the IF function argument separators

   The formula lacks commas between the condition and the true/false results.

2. Step 2: Correct the formula syntax

   It should be =IF(A1>100, "High", "Low") with commas separating arguments.

3. Final Answer:

   Missing commas between arguments -> Option B

4. Quick Check:

   Arguments must be comma-separated = Missing commas between arguments [OK]

Hint: Always separate IF arguments with commas [OK]

Common Mistakes:

• Forgetting commas between arguments
• Using semicolons or spaces instead
• Misplacing quotes around text

5. You want to assign a grade based on score in cell C3: "A" if score is 90 or above, "B" if 80 to 89, and "F" otherwise. Which formula correctly uses nested IF functions?

hard

A. =IF(C3>90, "A", IF(C3>80, "B", "F"))

B. =IF(C3>=90, "A", IF(C3>=70, "B", "F"))

C. =IF(C3>=90, "A", IF(C3>=80, "B", "F"))

D. =IF(C3>=90, "A", IF(C3>80, "B", "F"))

Solution

1. Step 1: Understand the grading rules

   Score 90 or above = "A", 80 to 89 = "B", below 80 = "F".

2. Step 2: Check nested IF logic and conditions

   =IF(C3>=90, "A", IF(C3>=80, "B", "F")) correctly checks if C3≥90 for "A", else if C3≥80 for "B", else "F".

3. Final Answer:

   =IF(C3>=90, "A", IF(C3>=80, "B", "F")) -> Option C

4. Quick Check:

   Nested IF with correct ranges = =IF(C3>=90, "A", IF(C3>=80, "B", "F")) [OK]

Hint: Use nested IFs with descending conditions for ranges [OK]

Common Mistakes:

• Using > instead of ≥ causing wrong grade boundaries
• Incorrect second condition range
• Missing nested IF structure
