Automotive

✓Electronics is the largest sales category, contributing about 30% of total sales.

✓Clothing and Home & Garden are also significant contributors.

✓Smaller categories like Automotive and Books contribute less to total sales.

Bonus Challenge

Create a second pie chart that shows sales distribution only for categories with sales above 5000.

Show Hint

Use a filter or create a new table with only categories where Sales Amount > 5000, then create a pie chart from that filtered data.

Practice

1. What does a pie chart in Google Sheets best represent?

easy

A. Trends over time with lines

B. Parts of a whole as slices of a circle

C. Exact values in a table

D. Relationships between two variables

Solution

1. Step 1: Understand pie chart purpose

   A pie chart visually shows how different parts contribute to a total.

2. Step 2: Match chart type to description

   Only Parts of a whole as slices of a circle describes parts of a whole as slices of a circle, which is a pie chart.

3. Final Answer:

   Parts of a whole as slices of a circle -> Option B

4. Quick Check:

   Pie chart = parts of whole [OK]

Hint: Pie charts show parts of a whole, like slices of a pizza [OK]

Common Mistakes:

• Confusing pie charts with line charts
• Thinking pie charts show exact numbers
• Using pie charts for trends over time

2. Which of these is the correct way to insert a pie chart in Google Sheets?

easy

A. Right-click a cell and select 'Add Pie Chart'

B. Type =PIECHART() in a cell

C. Use the formula =CHART(Pie, A1:B5)

D. Select data, then Insert > Chart, and choose Pie chart

Solution

1. Step 1: Recall how to insert charts in Google Sheets

   You select the data range, then go to Insert menu and choose Chart.

2. Step 2: Choose the correct chart type

   After opening the Chart editor, select Pie chart as the chart type.

3. Final Answer:

   Select data, then Insert > Chart, and choose Pie chart -> Option D

4. Quick Check:

   Insert menu > Chart > Pie chart [OK]

Hint: Use Insert > Chart, then pick Pie chart from options [OK]

Common Mistakes:

• Trying to create pie charts with formulas
• Looking for pie chart options in right-click menu
• Using non-existent functions like =PIECHART()

3. Given this data in A1:B4:
Fruit | Quantity
Apple | 30
Banana | 20
Cherry | 50
What percentage slice will Cherry have in a pie chart?

medium

A. 50%

B. 30%

C. 20%

D. 50 slices

Solution

1. Step 1: Calculate total quantity

   Total = 30 (Apple) + 20 (Banana) + 50 (Cherry) = 100

2. Step 2: Calculate Cherry's percentage

   Cherry's percentage = (50 / 100) * 100 = 50%

3. Final Answer:

   50% -> Option A

4. Quick Check:

   Cherry = 50% of total [OK]

Hint: Divide part by total, multiply by 100 for percentage [OK]

Common Mistakes:

• Using raw quantity instead of percentage
• Adding quantities incorrectly
• Confusing percentage with slice count

4. You created a pie chart but it shows incorrect slices. The data range is A1:B5 but your data is only in A1:B4. What is the likely fix?

medium

A. Change data range to A1:B4 to match actual data

B. Add a new row with zero values at A5:B5

C. Use a line chart instead

D. Delete the chart and start over

Solution

1. Step 1: Identify data range mismatch

   The chart includes an extra row (A5:B5) which may be empty or have wrong data.

2. Step 2: Correct the data range

   Adjust the data range to only include actual data cells A1:B4 to fix the slices.

3. Final Answer:

   Change data range to A1:B4 to match actual data -> Option A

4. Quick Check:

   Data range must match data size [OK]

Hint: Match chart data range exactly to your data cells [OK]

Common Mistakes:

• Ignoring extra empty rows in data range
• Trying unrelated chart types
• Deleting chart unnecessarily

5. You want to create a pie chart showing sales by region, but your data has some regions with zero sales. How should you prepare your data for the pie chart?

hard

A. Use a bar chart instead because pie charts can't handle zeros

B. Keep zero sales regions; pie chart will show empty slices

C. Remove regions with zero sales before creating the chart

D. Replace zero sales with 1 to show small slices

Solution

1. Step 1: Understand pie chart behavior with zero values

   Pie charts do not show slices for zero values, which can confuse viewers if zeros appear as empty slices.

2. Step 2: Prepare data by removing zero sales regions

   Removing zero sales rows keeps the chart clean and only shows meaningful slices.

3. Final Answer:

   Remove regions with zero sales before creating the chart -> Option C

4. Quick Check:

   Exclude zero values for clear pie charts [OK]

Hint: Exclude zero values to avoid confusing empty slices [OK]

Common Mistakes:

• Leaving zero sales which create misleading empty slices
• Replacing zeros with fake values
• Switching chart types unnecessarily
