Random sampling examples include: simple, systematic, stratified, and cluster sampling. Non-random sampling methods are liable to bias, and …
Nettetsuggests instantaneous sampling to calculate the variation size between two behaviours, for instance the variation between females and males. While using continuous sampling, Martin and Bateson (2011) state that each behaviour is recorded along with the time it started and the time it ended, in a way that the behaviours'
