An indirect measure is an unobtrusive measure that occurs naturally in a research context. The researcher is able to collect the data without introducing any formal measurement procedure. The types of indirect measures that may be available are limited only by the researcher's imagination and inventiveness.nobtrusive measurement presumably reduces the biases that result from the intrusion of the researcher or measurement instrument.

A post-office box or post office box (commonly referred to as a PO box or a postal box) is a uniquely addressable lockable box located on the premises of a post office station.
