🔍 Using Segmentation to Find Insights
What is Segmentation?
Breaking data into smaller groups to understand behavior, preferences, or performance.
Filtering vs. Segmenting
-
Filters = hide data

Segments = compare data
Examples

Demographics (age, gender)
-
Geography (state, country)
-
Behavior (purchase patterns)
🧮 Creating Calculated Fields
Simple Math to Powerful Logic
Right-click → “Create Calculated Field” to build:
-
Profit = Revenue – Cost
-
Growth Rate = (Current – Previous) / Previous
IF, CASE, and LOD Expressions
Use IF-THEN, CASE, and Level of Detail (LOD) for advanced scenarios like cohort analysis.
When to Use Calculated Fields
Whenever your raw data needs transformation or enrichment.
📖 Turning Data into Stories
Using Storyboards in Tableau
Create “story points”—visual pages that guide your audience step by step.
Annotating Key Moments
Highlight trends, spikes, or outliers. Add callouts like:
-
“Sales dropped in Q2 due to X”
-
“This region outperformed others”
Presenting to Non-Technical Audiences
Use plain English. Show comparisons, trends, and outcomes clearly. Avoid jargon.
