Eight Lessons You Can Learn From a Matchback

2. Statistical significance of your results. Did you receive enough responses to statistically prove that a result isn’t an anomaly but rather is representative of a pattern?

By performing a matchback, you increase the likelihood that groups will reach that minimum 50 responses, thereby enabling you to conclude statistically significant response patterns for each group.
