1001	Notebook	10	5	3
1002	Pen	20	2	1
1003	Notebook	5	5	3
1004	Pen	15	2	1
1005	Folder	7	4	2
1006	Folder	3	4	2

Dashboard Components

• Total Sales per Product (KPI card)
  Formula: =SUMPRODUCT((B2:B7=F2)*(C2:C7)*(D2:D7))
  Explanation: Calculates total sales for product in F2 by multiplying quantity and unit price for matching product rows.
• Average Sales per Order (KPI card)
  Formula: =AVERAGEIF(B2:B7,F2,C2:C7*D2:D7)
  Explanation: Finds average sales amount per order for product in F2.
• Profit Margin % (Calculated field)
  Formula: =((D2*C2)-(E2*C2))/(D2*C2) in row context
  Explanation: Calculates profit margin percentage per order by subtracting cost from sales and dividing by sales.
• Summary Table (Table showing Product, Total Sales, Average Sales, Profit Margin %)
  Uses formulas above for each product Notebook, Pen, Folder listed in F2:F4.

Interactivity

User can change the product name in cells F2, F3, F4 to see updated KPIs and summary table values for that product. This acts like a filter for product selection.

Self Check

If you change the product name in cell F2 from "Notebook" to "Pen", which components update their values?

• Total Sales KPI for F2
• Average Sales KPI for F2
• Profit Margin KPI for F2
• Summary Table row for that product

Key Result

Dashboard shows total sales, average sales per order, and profit margin for selected products using calculated fields.

Practice

1. What does a calculated field in Google Sheets do?

easy

A. Deletes data from the spreadsheet

B. Creates new values by using formulas on existing cells

C. Changes the font style of cells

D. Saves the spreadsheet automatically

Solution

1. Step 1: Understand the purpose of calculated fields

   Calculated fields use formulas to create new values based on existing data in cells.

2. Step 2: Compare options with this purpose

   Only Creates new values by using formulas on existing cells describes creating new values using formulas, which matches the definition.

3. Final Answer:

   Creates new values by using formulas on existing cells -> Option B

4. Quick Check:

   Calculated field = new values from formulas [OK]

Hint: Calculated fields always create new values from existing data [OK]

Common Mistakes:

• Confusing formatting changes with calculated fields
• Thinking calculated fields delete data
• Assuming calculated fields save files

2. Which of these formulas correctly calculates the total price if quantity is in A2 and price per item is in B2?

easy

A. =A2*B2

B. =A2+B2

C. =A2-B2

D. =A2/B2

Solution

1. Step 1: Identify the calculation needed

   Total price = quantity x price per item, so multiply A2 by B2.

2. Step 2: Match formula to calculation

   Only formula =A2*B2 multiplies the two cells correctly.

3. Final Answer:

   =A2*B2 -> Option A

4. Quick Check:

   Multiply quantity and price = total price [OK]

Hint: Use * to multiply quantity and price for total [OK]

Common Mistakes:

• Using + instead of * for multiplication
• Dividing instead of multiplying
• Subtracting values instead of multiplying

3. Given the formula =C2*D2+E2 where C2=5, D2=3, and E2=10, what is the result?

medium

A. 25

B. 15

C. 25.0

D. 18

Solution

1. Step 1: Calculate multiplication part

   Multiply C2 and D2: 5 * 3 = 15.

2. Step 2: Add E2 value

   Add 15 + 10 = 25.

3. Final Answer:

   25 -> Option A

4. Quick Check:

   5*3+10 = 25 [OK]

Hint: Multiply first, then add according to formula order [OK]

Common Mistakes:

• Adding before multiplying
• Ignoring order of operations
• Confusing cell values

4. The formula =A2*B2+C2 gives wrong results. Which fix is correct if you want to add B2 and C2 first, then multiply by A2?

medium

A. =A2*B2*C2

B. =(A2*B2)+C2

C. =A2+B2+C2

D. =A2*(B2+C2)

Solution

1. Step 1: Understand the desired calculation

   You want to add B2 and C2 first, then multiply by A2.

2. Step 2: Use parentheses to change order

   Formula =A2*(B2+C2) adds B2 and C2 first, then multiplies by A2.

3. Final Answer:

   =A2*(B2+C2) -> Option D

4. Quick Check:

   Parentheses change order to add first [OK]

Hint: Use parentheses to control calculation order [OK]

Common Mistakes:

• Ignoring parentheses and wrong order
• Adding all values instead of multiplying
• Multiplying all values without addition

5. You have a list of sales in column A and a fixed tax rate of 8% in cell B1. Which formula in column B calculates the total price including tax for each sale in A2, A3, etc.?

hard

A. =A2 + B1

B. =A2 / B1

C. =A2 * (1 + B1)

D. =A2 * B1

Solution

1. Step 1: Understand the calculation for total price with tax

   Total price = sale amount + tax amount. Tax amount = sale x tax rate.

2. Step 2: Write formula combining sale and tax

   Total price = sale x (1 + tax rate). So formula is =A2*(1+B1).

3. Final Answer:

   =A2 * (1 + B1) -> Option C

4. Quick Check:

   Multiply sale by (1 + tax rate) for total [OK]

Hint: Multiply by (1 + tax rate) to add tax [OK]

Common Mistakes:

• Adding tax rate directly instead of multiplying
• Multiplying only by tax rate (missing original amount)
• Dividing by tax rate
