TechFact Statistics based on a small sample size will appear more credible if the nature of the surveyed population is identified. Just describe the sample size in the "notes to TechValidate staff" field when you publish the TechFact.
Ex. (“beta customers”, “financial services customers”, "surveyed users") and TechValidate can attribute the source with more specificity (e.g. “Source: Survey of 15 Acme beta customers”)
