The packet error rate (PER) is the number of incorrectly received data packets divided by the total number of received packets. A packet is declared incorrect if at least one bit is erroneous. The expectation value of the PER is denoted packet error probability pp, which for a data packet length of N bits can be expressed as
- ,
assuming that the bit errors are independent of each other. For small bit error probabilities, this is approximately
Similar measurements can be carried out for the transmission of frames, blocks, or symbols.

“we know our end
A packet of worm-seed, a garden of spent tissues.”
—Allen Tate (1899–1979)
“Meanwhile, if the fear of falling into error sets up a mistrust of Science, which in the absence of such scruples gets on with the work itself, and actually cognizes something, it is hard to see why we should not turn round and mistrust this very mistrust.... What calls itself fear of error reveals itself rather as fear of the truth.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“We honor motherhood with glowing sentimentality, but we don’t rate it high on the scale of creative occupations.”
