Common Mistakes

Using Table or Matrix which display data but don't filter

Choosing Card which shows single values

A slicer visual allows users to filter report data interactively by fields like 'Region'.

💡 Hint

Common Mistakes

Using column name without table

Reversing table and column names

The correct syntax for SUM requires the table and column name in the format Table[Column].

4fill in blank

Fill both blanks to create a measure that calculates average sales per region.

Power BI

AvgSalesPerRegion = AVERAGEX(VALUES([1]), CALCULATE(SUM([2])))

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

ASales[Region]

CRegion[Sales]

DAmount[Sales]

💡 Hint

Common Mistakes

Swapping table and column names

Using incorrect table names

VALUES(Sales[Region]) gets unique regions, and SUM(Sales[Amount]) sums sales per region for averaging.

5fill in blank

hard

Fill all three blanks to create a calculated column that flags high sales over 1000.

Power BI

HighSalesFlag = IF([1] > [2], [3], "No")

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

ASales[Amount]

B1000

C"Yes"

DSales[Region]

💡 Hint

Common Mistakes

Using region column instead of amount

Using number as string incorrectly

This IF statement checks if Sales[Amount] is greater than 1000, then flags "Yes", else "No".

3. Final Answer:

   Resize and align visuals properly; use consistent font sizes in Format pane -> Option B

4. Quick Check:

   Fix layout + consistent fonts [OK]

Hint: Fix layout and fonts in Format pane, don't ignore problems [OK]

Common Mistakes:

• Ignoring layout issues
• Adding distracting colors instead of fixing layout
• Deleting report unnecessarily

5. You want to create a sales report that guides users to key insights. Which combination of design choices best achieves this?

D. Add all possible visuals on one page without grouping or titles

Solution

1. Step 1: Add clear titles to guide users

   Titles help users understand what each visual shows and what to focus on.

2. Step 2: Use color to highlight key data points

   Thoughtful color use draws attention to important insights without overwhelming.

3. Step 3: Arrange visuals logically to tell a story

   A logical flow helps users follow the data story step-by-step.

4. Final Answer:

   Use a clear title, highlight important data with color, and arrange visuals in a logical flow -> Option C

5. Quick Check:

   Title + color highlight + logical flow [OK]

Hint: Guide users with titles, colors, and logical layout [OK]

Common Mistakes:
