¶ … sampling methods that can be used in quantitative research. The first is simple random sampling. This method allows the researcher to get a truly representative sample of the population, free from any bias. Whether simple random sampling is easy or not depends to some extent on the nature of the population. Simple random sampling does not involve targeting any sub-grouping within the population, but it does deliver a more globally representative sample.
Another method is stratified sampling, wherein the researcher targets specific sub-groups. An example of this would be using demographics to break down groups. Marketers commonly use stratified sampling to understand how specific demographics respond to their products. A company might use simple random sampling, but if it wants to test a specific ad campaign for effectiveness in a target demo, then it would use stratified sampling in order to ensure that all members of the sample are within that demo. The advantage is that you have a more targeted population, in particular one that should be more meaningful to the study. The downside is that there is no feedback gained from anybody outside of the strata, which reduces the ability of the results to be replicated universally.
Systematic sampling is another method. This is when the researcher samples every nth person. The approach is fairly easy, and would seem to deliver a random sample, but that assumes that the population is distributed randomly. If the population is not distributed randomly, the researcher...
Introduction This paper examines three scholarly articles and discusses the sampling technique associated with the studies. The first is a critique by Mayes (2015). The second is a Level VII study by Wetter and Hodge (2016). The third is a Level V study by Pause (2017). These three studies offer different approaches to the sample of data used in each of the studies and thus examining each provides an opportunity to
Sampling Techniques Reveal Media Psychology The first study of focus regards perceptions of news media bias and how individual and interpersonal factors affect those perceptions. The sampling method used in this study is non-probability. The researchers worked in conjunction with an international marketing company. The company contacted a massive quantity of people via mail inquiring for participation via mail and via telephone; they had more than 500, 000 participants. The researchers
Bluegill Fish Populations: Sampling Methods Field research can often depend on the quality and reliability of the equipment used to record samples and observations. If researchers fail to understand their sampling measures and any potential limitations they present, the end result of the data collection and observations may not have the validity required to make realistic conclusions about the population in question. Such is the case for studying fish populations, as
Methods for Recording ObservationsThere are many methods available for recording observations namely video and audio recording, note taking, drawing sketches, photographs, or using computerized recorders. The most effective method for recording observations is video and audio recording. This method will not only allow for the capture of behavior, but also capturing the exact manner of how the behavior is enacted. Using video and audio recording, one can also capture the
Sampling Strategy and Sample Size for a Quantitative Research Plan [To what extent do African-American men who live in an urban setting and exhibit aggressive behavior due to early development factors associated with depression receive a diagnosis at local medical facilities of conduct disorder as opposed to depression?] The question posed in this study is one asking 'To what extent do African-American men who live in an urban setting and exhibit aggressive
Sampling Size Sampling Strategy and Sample Size for a Qualitative Research Plan A grounded theory perspective on the victimization of women and human trafficking The formulas for determining appropriate sampling sizes for quantitative research studies are fairly formalized, given the need to make generalizations about the macro-level population based upon the findings of these experimental or quasi-experimental studies. However, the purpose of qualitative studies is to come to conclusions based upon the researcher's
