In contrast, probability methods (methods that are randomized) include simple sampling, systemic sampling, and cluster sampling (Privitera, 2023; GCU, 2017). Simple sampling is a basic method where each individual has an equal chance of being selected. Thus, one major advantage to note is minimizing bias while one disadvantage is how time- consuming it is (Privitera, 2023). The second method, systemic sampling, is selecting every nth person after a randomized starting point (Privitera, 2023; GCU, 2017). One advantage of this method is the ease of implementing it compared to the simple randomized method. However, one disadvantage is the fact that it's less random which may still have space for bias (Privitera, 2023). The third and last method, cluster sampling, is dividing the population of interest into naturally occurring "clusters" or groups. (GCU, 2017). One advantage of this method is the ability to break down a largely dispersed population into subgroups (Privitera, 2023). while, one disadvantage may be its questionable accuracy when some clusters are omitted and others aren't really representative of the population in question (Privitera, 2023)." create a respone to this
