Florencia used a systematic random sampling method by selecting every fourth name on the list. This is different from simple random sampling, where every member of the population has an equal chance of being selected, and stratified random sampling, where the population is divided into subgroups and a random sample is taken from each subgroup. Florencia's method is also not proportionate random sampling, as there is no consideration of the distribution of the population. Lastly, it is not a non-probability sampling method as she had a specific plan for selecting the sample.
