A '''simple random sample''' (sometimes '''SRS''', oftentimes '''random sample''') is a method of taking a sample from the target population  with completely randomised selection in order to minimise bias. More complex versions of the simple random sample include [[stratified random sampling]] and introducing [[block design]] to random sampling.
