Eliminating duplicates improves the reliability of findings, supports accurate segmentation and helps create more personalized marketing campaigns.

Removing duplicate phone numbers from focus group lists can eliminate skewed results, ensure a representative sample and draw insights that reflect customer behaviors and preferences. Ignoring this step could lead to flawed insights and misguided strategies.
