💡 Hint

Common Mistakes

Using a dash '-' instead of a colon ':' for ranges.

Separating cells with commas or semicolons instead of a colon.

The correct range syntax in Google Sheets uses a colon to specify a continuous range of cells, like A1:A5.

💡 Hint

Common Mistakes

Using a colon ':' when cells are not continuous.

Using semicolons or dashes instead of commas.

To average specific cells that are not in a continuous range, list them separated by commas inside the function.

💡 Hint

Common Mistakes

Using a dash '-' instead of a colon ':' for ranges.

Using commas or semicolons inside range references.

The colon ':' is required to specify a range from C1 to C3 in Google Sheets.

4fill in blank

Fill both blanks to calculate the average of cells D1 to D4 and ignore empty cells.

Google Sheets

=AVERAGE([1][2])

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

BD1,D4

CD1;D4

DD1-D4

💡 Hint

Common Mistakes

Adding extra characters after the range.

Using commas or semicolons instead of a colon.

The correct way to specify the range is D1:D4. The second blank is empty because the range is complete.

5fill in blank

Fill all three blanks to calculate the average of cells E1, E3, and E5.

Google Sheets

=AVERAGE([1],[2],[3])

💡 Hint

Common Mistakes

Including cells not intended like E2.

Using semicolons or dashes instead of commas.

List each cell separated by commas inside the AVERAGE function to include non-continuous cells.

Practice

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

easy

A. It adds all numbers and divides by the count of numbers.

B. It finds the biggest number in a list.

C. It counts how many numbers are in a list.

D. It multiplies all numbers together.

Solution

1. Step 1: Understand the purpose of AVERAGE

   The AVERAGE function sums all numeric values in a range and divides by how many numbers there are.

2. Step 2: Compare options with definition

   Only It adds all numbers and divides by the count of numbers. correctly describes this behavior.

3. Final Answer:

   It adds all numbers and divides by the count of numbers. -> Option A

4. Quick Check:

   AVERAGE = sum ÷ count [OK]

Hint: AVERAGE means sum numbers then divide by count [OK]

Common Mistakes:

• Thinking AVERAGE finds the biggest number
• Confusing AVERAGE with COUNT
• Assuming it multiplies numbers

2. Which of these is the correct way to write the AVERAGE formula for cells A1 to A5?

easy

A. =AVERAGE{A1:A5}

B. =AVERAGE[A1:A5]

C. =AVERAGE(A1:A5)

D. =AVERAGE A1:A5

Solution

1. Step 1: Recall correct formula syntax

   Google Sheets formulas use parentheses () to enclose cell ranges or arguments.

2. Step 2: Check each option

   Only =AVERAGE(A1:A5) uses parentheses correctly: =AVERAGE(A1:A5). Others use brackets, braces, or no parentheses, which are invalid.

3. Final Answer:

   =AVERAGE(A1:A5) -> Option C

4. Quick Check:

   Formulas need parentheses () [OK]

Hint: Use parentheses () for function arguments [OK]

Common Mistakes:

• Using square brackets [] instead of parentheses
• Using curly braces {} incorrectly
• Omitting parentheses

3. Given the values in cells A1=10, A2=20, A3=, A4="text", A5=30, what is the result of =AVERAGE(A1:A5)?

medium

A. Error

B. 15

C. 25

D. 20

Solution

1. Step 1: Identify numeric values in range

   Cells A1=10, A2=20, A5=30 are numbers; A3 is empty and A4 is text, both ignored by AVERAGE.

2. Step 2: Calculate average of numbers

   Sum = 10 + 20 + 30 = 60; Count = 3; Average = 60 ÷ 3 = 20.

3. Final Answer:

   20 -> Option D

4. Quick Check:

   Ignore empty/text, average numbers only [OK]

Hint: AVERAGE ignores empty cells and text [OK]

Common Mistakes:

• Including empty cells in count
• Including text as zero
• Expecting error due to text

4. The formula =AVERAGE(A1:A4, 10) returns an error. What is the likely cause?

medium

A. The syntax is incorrect; extra parentheses needed.

B. The formula is correct; error is elsewhere.

C. You cannot mix ranges and single numbers in AVERAGE.

D. You must separate arguments with semicolons, not commas.

Solution

1. Step 1: Verify formula syntax

   =AVERAGE(A1:A4, 10) is valid in Google Sheets; AVERAGE can take a range and a constant value as arguments.

2. Step 2: Determine error source

   Since the syntax is correct, the error must originate elsewhere, such as invalid data in A1:A4, cell references, or spreadsheet settings.

3. Final Answer:

   The formula is correct; error is elsewhere. -> Option B

4. Quick Check:

   AVERAGE(range, number) is valid [OK]

Hint: AVERAGE accepts ranges + numbers; check data/range [OK]

Common Mistakes:

• Assuming mixing ranges and numbers is invalid
• Using wrong argument separators
• Missing equal sign at start

5. You have sales data in cells B2:B10, but some cells contain text notes. Which formula correctly calculates the average sales ignoring text?

hard

A. =AVERAGE(B2:B10)

B. =SUM(B2:B10)/COUNTA(B2:B10)

C. =AVERAGEIF(B2:B10, ">0")

D. =AVERAGE(B2:B10, "text")

Solution

1. Step 1: Understand how AVERAGE handles text

   AVERAGE automatically ignores text and empty cells when calculating the average.

2. Step 2: Evaluate each option

   =AVERAGE(B2:B10) uses AVERAGE directly, which works correctly. =SUM(B2:B10)/COUNTA(B2:B10) counts text cells, causing wrong divisor. =AVERAGEIF(B2:B10, ">0") averages only numbers >0, excluding zeros. =AVERAGE(B2:B10, "text") includes text as argument, causing error.

3. Final Answer:

   =AVERAGE(B2:B10) -> Option A

4. Quick Check:

   AVERAGE ignores text automatically [OK]

Hint: Use AVERAGE directly; it skips text cells [OK]

Common Mistakes:

• Using COUNTA which counts text too
• Trying to filter numbers manually
• Adding text as argument causing errors
