The answer is the Modeling tab’s New Measure button and right-clicking a table in the Fields pane to select New Measure. Both methods trigger the same DAX formula bar, allowing you to write calculated measures that dynamically aggregate data at query time rather than storing values in the table. On the PL-300 exam, this question tests your familiarity with the two primary entry points for measure creation, often appearing early in the modeling section to ensure you know the difference between calculated columns and measures. A common trap is confusing the “New Column” button with “New Measure,” so remember that measures live in the Fields pane under the table but are computed on the fly. Memory tip: think “Model or Right-Click” — both get you to the same DAX editor.
PL-300 Visualize and analyze the data Practice Question
This PL-300 practice question tests your understanding of visualize and analyze the data. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO of the following are valid ways to create a measure in Power BI?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
From the Modeling tab, click New Measure.
Option A is correct because the Modeling tab in Power BI Desktop provides a dedicated 'New Measure' button that allows users to create calculated measures using DAX (Data Analysis Expressions). This is the primary and most direct method for adding measures to your data model, enabling dynamic aggregations and calculations that are not stored in the table but computed at query time.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
From the Modeling tab, click New Measure.
Why this is correct
This is the standard way to create a measure.

✓
Right-click a table in the Fields pane and select New Measure.
Why this is correct
This is another valid method.

✗
From the Format pane, add a measure.
Why it's wrong here
The Format pane is for visual formatting.
✗
From Power Query Editor, add a custom column.
Why it's wrong here
Power Query is for data transformation, not measures.
✗
From the Visualizations pane, click New Measure.
Why it's wrong here
The Visualizations pane does not have this option.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the Format pane or Visualizations pane with measure creation tools, or mistakenly think Power Query Editor can create measures, when in fact measures are exclusively created via the Modeling tab or by right-clicking a table in the Fields pane.
Detailed technical explanation
How to think about this question
Measures in Power BI are DAX formulas that are evaluated in the context of the current filter, row, and query context, making them essential for dynamic calculations like running totals or year-over-year growth. Unlike calculated columns (which are computed row-by-row during data refresh and stored in memory), measures are computed at query time, which can significantly reduce model size and improve performance. A real-world scenario is creating a 'Total Sales' measure that sums the 'SalesAmount' column — this measure automatically recalculates when a user filters by date or region, without requiring additional storage.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
