[Type of fallacy] Statistics of small numbers [Example] "Our membership has increased 100% in the last year." (In reality, this could mean that the one prior member has recruited an additional member, and says nothing about the total number of members. An organization with 100,000 members which grows by 100% has increased its membership by 100,000, a far cry from increasing membership by one more member.) [Definition]
