Natural Resource BiometricsSequential SamplingIn sequential sampling we are taking a sample without knowing the sample size before we start. As opposed to the classical sampling, where we have two possibilities (accept or reject the null hypothesis). In sequential sampling we have three or more possibilities (accept, reject or uncertainty about the null hypothesis). Then you are in the uncertainty condition you usually continue to sample. A simple exampleIn Krebs (1989), he presents an example of rainbow trout put in the effluent coming from a coal processing plant. We are know from previous studies that the mean survival time should be less than 36 hours. We follow these steps:
