Practice - 5 Tasks

1fill in blank

easy

Complete the formula to color every other row starting from the first row.

Google Sheets

=ISEVEN([1]())

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

💡 Hint

Common Mistakes

Using COLUMN() instead of ROW()

Using CELL() which needs extra parameters

Using INDEX() which is for retrieving values

The ROW() function returns the row number of the current cell. Using ISEVEN(ROW()) colors even rows.

2fill in blank

medium

Complete the formula to color odd rows instead of even rows.

Google Sheets

=IS[1](ROW())

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

AEVEN

DISNUMBER

💡 Hint

Common Mistakes

Using ISNUMBER which just checks if a value is a number

Using MOD without proper parameters

Using EVEN which checks for even numbers

Using ISODD(ROW()) returns TRUE for odd rows, so you can color odd rows.

3fill in blank

hard

Fix the error in the formula to color every third row starting from the first row.

Google Sheets

=MOD(ROW(), [1]) = 0

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

A0

B2

C1

D3

💡 Hint

Common Mistakes

Using 2 colors every second row instead of every third

Using 1 which colors every row

Using 0 which causes an error

The MOD(ROW(), 3) = 0 formula returns TRUE for every third row (3, 6, 9, ...).

4fill in blank

hard

Fill both blanks to color rows where the row number is divisible by 4 and the column number is even.

Google Sheets

=AND(MOD(ROW(), [1]) = 0, ISEVEN([2]()))

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

A4

B3

CCOLUMN

DROW

Attempts:

💡 Hint

Common Mistakes

Using ROW() instead of COLUMN() for the second blank

Using 3 instead of 4 for the divisor

Mixing up the order of conditions

The formula colors rows divisible by 4 and columns that are even numbers. MOD(ROW(), 4) = 0 checks rows, ISEVEN(COLUMN()) checks columns.

5fill in blank

hard

Fill all three blanks to color rows where the row number is odd, the column number is odd, and the row number is less than 10.

Google Sheets

=AND(IS[1](ROW()), IS[2](COLUMN()), ROW() [3] 10)

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

AODD

C<

DEVEN

💡 Hint

Common Mistakes

Using ISEVEN instead of ISODD

Using > instead of < for the row limit

Mixing up row and column functions

This formula colors cells where the row is odd, the column is odd, and the row number is less than 10. It uses ISODD for row and column checks and < for the comparison.

Practice

1. What is the main purpose of using Alternating row colors in Google Sheets?

easy

A. To protect cells from editing

B. To sort data alphabetically

C. To add formulas automatically

D. To make rows easier to read by shading every other row

Solution

1. Step 1: Understand the feature's function

   Alternating row colors shade every other row to improve readability.

2. Step 2: Compare options with the feature's purpose

   Only To make rows easier to read by shading every other row describes shading rows for easier reading, others describe unrelated features.

3. Final Answer:

   To make rows easier to read by shading every other row -> Option D

4. Quick Check:

   Alternating row colors = shading rows [OK]

Hint: Think: Why shade rows? To read easier! [OK]

Common Mistakes:

• Confusing alternating colors with sorting
• Thinking it adds formulas automatically
• Assuming it protects cells

2. Which of the following is the correct way to apply alternating row colors using a custom formula in Google Sheets?

easy

A. Use formula =ROW() in the custom formula box

B. Use formula =ISEVEN(ROW()) in the custom formula box

C. Use formula =COLUMN()=1 in the custom formula box

D. Use formula =SUM(A1:A10) in the custom formula box

Solution

1. Step 1: Identify formula for alternating rows

   The formula =ISEVEN(ROW()) returns TRUE for even rows, perfect for shading every other row.

2. Step 2: Check other formulas

   =ROW() returns row number, not TRUE/FALSE; =COLUMN()=1 checks columns, not rows; =SUM(A1:A10) sums values, unrelated to row shading.

3. Final Answer:

   Use formula =ISEVEN(ROW()) in the custom formula box -> Option B

4. Quick Check:

   ISEVEN(ROW()) = alternate rows [OK]

Hint: Use ISEVEN or ISODD with ROW() for alternating rows [OK]

Common Mistakes:

• Using ROW() alone without ISEVEN or ISODD
• Confusing columns with rows in formula
• Using unrelated functions like SUM

3. Given the custom formula =ISODD(ROW()) applied for alternating row colors starting from row 2, which rows will be shaded?

medium

A. Rows 1, 3, 5, 7, ...

B. Rows 2, 4, 6, 8, ...

C. Only row 1

D. No rows will be shaded

Solution

1. Step 1: Understand ISODD(ROW()) behavior

   ISODD(ROW()) returns TRUE for rows with odd numbers: 1, 3, 5, etc.

2. Step 2: Consider starting from row 2

   Even if shading starts at row 2, the formula checks actual row numbers, so rows 1, 3, 5... are shaded.

3. Final Answer:

   Rows 1, 3, 5, 7, ... -> Option A

4. Quick Check:

   ISODD(ROW()) = odd rows shaded [OK]

Hint: ISODD(ROW()) shades odd rows, regardless of start [OK]

Common Mistakes:

• Assuming shading starts exactly at row 2
• Confusing odd and even rows
• Thinking no rows are shaded

4. You applied the formula =ISEVEN(ROW()) for alternating row colors but no rows are shaded. What is the most likely reason?

medium

A. The formula was entered without the equals sign

B. The sheet has no data

C. The formula should be =ISODD(COLUMN())

D. Alternating colors only work on columns, not rows

Solution

1. Step 1: Check formula syntax

   Conditional formatting formulas must start with an equals sign to work properly.

2. Step 2: Evaluate other options

   Sheet data presence doesn't affect shading; =ISODD(COLUMN()) shades columns, not rows; alternating colors do work on rows.

3. Final Answer:

   The formula was entered without the equals sign -> Option A

4. Quick Check:

   Formula needs = sign to work [OK]

Hint: Always start formulas with = in conditional formatting [OK]

Common Mistakes:

• Omitting the equals sign in formulas
• Confusing row and column functions
• Believing alternating colors don't work on rows

5. You want to shade every third row starting from row 2 in Google Sheets using a custom formula for alternating colors. Which formula should you use?

hard

A. =ISODD(ROW())

B. =ISEVEN(ROW())

C. =MOD(ROW()-2, 3) = 0

D. =MOD(COLUMN(), 3) = 0

Solution

1. Step 1: Understand the requirement

   Shading every third row starting at row 2 means rows 2, 5, 8, etc. should be shaded.

2. Step 2: Analyze the formula options

   =MOD(ROW()-2, 3) = 0 returns TRUE for rows where (row number minus 2) is divisible by 3, matching rows 2, 5, 8... Others either shade every even/odd row or columns, not every third row.

3. Final Answer:

   =MOD(ROW()-2, 3) = 0 -> Option C

4. Quick Check:

   MOD with ROW() controls row intervals [OK]

Hint: Use MOD(ROW()-start, interval)=0 for custom row patterns [OK]

Common Mistakes:

• Using ISEVEN or ISODD for every third row
• Applying MOD to COLUMN() instead of ROW()
• Not adjusting row number by start offset
