Calculate total sales using structured table references

Given an Excel table named SalesData with columns Product and Amount, what is the result of the formula =SUM(SalesData[Amount]) if the Amount column contains values 100, 200, and 300?

A SUM(SalesData)

B 100

C 600

D 3

💡 Hint

The formula sums all numbers in the Amount column of the table.

The formula =SUM(SalesData[Amount]) adds all values in the Amount column of the SalesData table: 100 + 200 + 300 = 600.

❓ Function Choice

Choose the correct formula to count rows in a table

You have a table named Employees with a column Name. Which formula correctly counts how many rows are in the table?

A =COUNTA(Employees[Name])

B =ROWS(Employees)

C =COUNT(Employees[Name])

D =COUNTIF(Employees, "*")

💡 Hint

Counting non-empty cells in a column counts rows.

COUNTA counts all non-empty cells in the Name column, effectively counting rows. ROWS(Employees) returns the number of rows including header and totals which is not valid for tables. COUNT counts only numbers, so it may miss text names. COUNTIF with a table reference is invalid syntax.

Result of formula using table and column references with filters

In a table named Orders with columns Status and Amount, the Status column has values: "Complete", "Pending", "Complete" and the Amount column has values: 150, 200, 100. What is the result of the formula =SUMIFS(Orders[Amount], Orders[Status], "Complete")?

A 450

B 250

C 200

D Syntax Error

💡 Hint

SUMIFS sums amounts where Status equals "Complete".

The formula sums Amount values where Status is "Complete": 150 + 100 = 250.

🎯 Scenario

Identify the error in a formula using table references

You wrote the formula =SUM(Table1[Price]) + Table1[Quantity] in a cell. What will happen when you enter this formula?

A It returns a #VALUE! error because you cannot add a range to a range directly

B It returns the sum of Price column plus the sum of Quantity column

C It returns the sum of Price column only

D It returns the sum of Quantity column only

💡 Hint

Adding two ranges directly causes an error.

You cannot add two ranges directly in Excel formulas. Adding Table1[Price] + Table1[Quantity] causes a #VALUE! error because Excel does not know how to add arrays without aggregation.

Determine the number of unique products sold using table references

Given a table named Sales with a column Product containing: "Apple", "Banana", "Apple", "Orange", "Banana", which formula correctly returns the number of unique products sold?

A =COUNTA(Sales[Product])

B =COUNTIF(Sales[Product], "<>Apple")

C =COUNT(Sales[Product])

D =SUMPRODUCT(1/COUNTIF(Sales[Product], Sales[Product]))

💡 Hint

Use a formula that counts unique text values in a column.

The formula =SUMPRODUCT(1/COUNTIF(Sales[Product], Sales[Product])) counts unique values by dividing 1 by the count of each product and summing these fractions, resulting in 3 unique products: Apple, Banana, Orange.
