Complete the formula to check if A1 is greater than 10.

Google Sheets

=IF(A1 [1] 10, "Yes", "No")

Drag options to blanks, or click blank then click option'

B<

C=

D<=

💡 Hint

Common Mistakes

Using '<' instead of '>' will check the wrong condition.

Using '=' will check if A1 equals 10, not greater.

The IF function tests if A1 is greater than 10 using the '>' operator.

Complete the formula to return TRUE if B2 equals 5.

Google Sheets

=IF(B2 [1] 5, TRUE, FALSE)

Drag options to blanks, or click blank then click option'

A=

B>=

C<

D>

Attempts:

💡 Hint

Common Mistakes

Using '>' or '<' checks for greater or less, not equality.

Using '>=' checks for greater or equal, not exact equality.

The '=' operator checks if B2 is exactly 5.

Fix the error in the formula to check if C3 is less than or equal to 20.

Google Sheets

=IF(C3 [1] 20, "OK", "Check")

Drag options to blanks, or click blank then click option'

A>

B<

C<=

D==

Attempts:

3 left

💡 Hint

Common Mistakes

Using '==' causes an error because Google Sheets uses '=' for equality.

Using '<' only checks less than, not less than or equal.

The correct operator for 'less than or equal to' is '<=' in Google Sheets.

4fill in blank

hard

Fill both blanks to create a formula that returns "Pass" if D4 is between 50 and 100 (inclusive).

Google Sheets

=IF(AND(D4 [1] 50, D4 [2] 100), "Pass", "Fail")

Drag options to blanks, or click blank then click option'

A>=

B<

C<=

D>

Attempts:

3 left

💡 Hint

Common Mistakes

Using '<' instead of '<=' excludes 100 from the range.

Using '>' instead of '>=' excludes 50 from the range.

The formula checks if D4 is greater than or equal to 50 and less than or equal to 100.

5fill in blank

hard

Fill all three blanks to create a formula that returns "Good" if E5 is greater than 70, "Average" if equal to 70, and "Poor" if less than 70.

Google Sheets

=IF(E5 [1] 70, "Good", IF(E5 [2] 70, "Average", IF(E5 [3] 70, "Poor", "Poor")))

Drag options to blanks, or click blank then click option'

A>

B=

C<

D>=

Attempts:

3 left

💡 Hint

Common Mistakes

Using '>=' instead of '>' changes the logic.

Using '=' in the first condition causes wrong results.

The formula first checks if E5 is greater than 70, then if equal to 70, else it is less than 70.

Practice

1. What does the IF function do in Google Sheets?

easy

A. It checks a condition and returns one value if true, another if false.

B. It adds numbers in a range.

C. It sorts data alphabetically.

D. It counts the number of cells with numbers.

Solution

1. Step 1: Understand the purpose of IF

   The IF function tests a condition and chooses between two results based on true or false.

2. Step 2: Compare options with IF's behavior

   Only It checks a condition and returns one value if true, another if false. describes this behavior correctly; others describe different functions.

3. Final Answer:

   It checks a condition and returns one value if true, another if false. -> Option A

4. Quick Check:

   IF function = condition check [OK]

Hint: IF means choose between two results based on true or false [OK]

Common Mistakes:

• Confusing IF with SUM or COUNT functions
• Thinking IF sorts data
• Assuming IF counts cells

2. Which of these is the correct syntax for the IF function in Google Sheets?

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 Google Sheets formula syntax

   Google Sheets uses commas to separate arguments in functions.

2. Step 2: Identify correct IF syntax

   =IF(condition, value_if_true, value_if_false) uses commas and parentheses correctly; others use wrong separators or brackets.

3. Final Answer:

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

4. Quick Check:

   Correct IF syntax uses commas and parentheses [OK]

Hint: Use commas inside parentheses for IF arguments [OK]

Common Mistakes:

• Using semicolons instead of commas
• Using curly braces or square brackets
• Missing parentheses

3. Given the formula =IF(A1>10, "High", "Low") and cell A1 contains 8, what will the formula return?

medium

A. TRUE

B. "High"

C. 8

D. "Low"

Solution

1. Step 1: Evaluate the condition A1>10

   Since A1 is 8, 8>10 is FALSE.

2. Step 2: Determine IF result based on condition

   Because condition is FALSE, IF returns the value_if_false, which is "Low".

3. Final Answer:

   "Low" -> Option D

4. Quick Check:

   8>10 is false, so result = "Low" [OK]

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

Common Mistakes:

• Assuming condition is true without checking
• Returning the cell value instead of IF result
• Confusing TRUE/FALSE with text results

4. The formula =IF(A1=5, "Yes", "No" is entered in a cell. What is wrong with this formula?

medium

A. Text values should not be in quotes.

B. Using = instead of == for comparison.

C. Missing closing parenthesis at the end.

D. IF function cannot compare numbers.

Solution

1. Step 1: Check formula syntax

   The formula has an opening parenthesis after IF but no closing parenthesis at the end.

2. Step 2: Verify other parts

   Using = for comparison is correct in Sheets, text in quotes is correct, and IF can compare numbers.

3. Final Answer:

   Missing closing parenthesis at the end. -> Option C

4. Quick Check:

   All functions need matching parentheses [OK]

Hint: Count parentheses to avoid missing one [OK]

Common Mistakes:

• Using double equals (==) like in programming
• Not putting text in quotes
• Thinking IF can't compare numbers

5. You want to create a formula that returns "Pass" if a student's score in cell B2 is 50 or more, and "Fail" otherwise. Which formula correctly uses logical functions to handle this condition?

hard

A. =IF(B2>=50, "Pass", "Fail")

B. =IF(B2>50, "Pass", "Fail")

C. =IF(B2=50, "Pass", "Fail")

D. =IF(B2<50, "Pass", "Fail")

Solution

1. Step 1: Understand the condition for passing

   Passing means score is 50 or more, so condition is B2 >= 50.

2. Step 2: Check each formula against the condition

   =IF(B2>=50, "Pass", "Fail") uses B2 >= 50 correctly. =IF(B2>50, "Pass", "Fail") excludes 50, =IF(B2=50, "Pass", "Fail") only checks exactly 50, =IF(B2<50, "Pass", "Fail") reverses logic.

3. Final Answer:

   =IF(B2>=50, "Pass", "Fail") -> Option A

4. Quick Check:

   Use >= for 50 or more condition [OK]

Hint: Use >= to include the boundary value [OK]

Common Mistakes:

• Using > instead of >= and missing exact 50
• Checking only equality (=50)
• Reversing true/false results
