Testing a population of 16 where only one is positive would require 16 tests. However, if the tests were pooled into 4 groups of 4 (as could be done with PCR for COVID-19 for example) only 8 tests would be needed. 4 tests for 4 groups of 4, then a further 4 individual tests for the 4 in the one group that was positive.
