Using the example of the 20,000 university students above, let us assume that the researcher is only interested in achieving a sample size of maybe 300 students. In this case, we will talk in-depth about non-probability sampling. Further, the researcher is interested in particular strata within the population. The moving average difference en may include an exponentially weighted moving average of a difference between two consecutive exponentially weighted moving averages of an operation parameter un of the signal communication channel. The researcher picks a single person or a group of people for sampling. Continuous outcome variables (quantified on an infinite arithmetic scale, for example, time) have the advantage over dichotomous outcome variables (only two categories, for example, dead or alive) of increasing the power of a study, permitting a smaller sample size.
