• If share semantic and cube similarity
• Use only if necessary
• Bigger sample size will decrease confidence interval

• Some dimensions are clear: Age
• Some are fuzzy: Occupation
• May need domain knowledge
• Cell value similarity
• How to determine if two cells’ samples come from the same population?
• Two-sample t-test (confidence-based)
