Cluster sampling

1. “When investigating a large population, it is often impractical and usually unnecessary to measure all the elements in the population of interest. Typically, a relatively small number of subject or cases is selected from the larger population.” (McMillian, 2012, p.96) According to McMillian (2012), population is a target you want to study to develop knowledge and to create action plans to assist those individuals. An example is when a researcher use a group of students with autism to find out…

was conducted (Gerbner, Living). However, additional biases could have potentially included a limited sampling size, a social desirability bias, and/or an acquiescence bias. With the personal nature of the study and the dependence on polling something as abstract as a perspective, there are many variables. With only having three surveys with a total of 2,010 participants, there was a limited sampling size. Based on the questions asked by the questionnaire, it could have also been very easy for…

The Beastie Boys were known for their unique lyrics and became the first successful, white rap group. The members gained loads of fame over the past three decades of music making. People were negatively inspired by listening to the strange lyrics in their earlier productions. The Beastie Boys had more of a positive impact on society than negative as they grew older and wiser. The first successful, white rap group formed in 1981 and shortly became popular on college radio stations and clubs. The…

on 1 What is the overall meaning of the poll? what does it show? describe the trend that is occurring. The overall meaning of the poll was to determine who voters would potentially support other than their already decided upon candidate. To explain, voters who had already made a clear distinction about which candidates they were likely to vote for, were asked, to reevaluate their decisions based on the information they gathered during the New Hampshire Republican and Democratic Presidential…

obtain, as participants may easily be accessible and available (Frankfort-Nachmias & Nachmias, 2008). However, it may skew the sample, tainting it through introducing sampling bias. As a result, this strategy may not culminate in a representative sample of the population (Frankfort-Nachmias & Nachmias, 2008). Likewise, purposive sampling has the drawback of being based on the subjective judgment of a researcher to obtain a sample (Frankfort-Nachmias & Nachmias, 2008). Since it is impossible to…

This will give the sampling method a larger pool to gather information to complete the research needed. What is the appropriate sampling size? The appropriate sampling size is achieved by many factors. These factors are the size of the study, population size, the purpose of the study, and the risk of selecting a wrong sample design. The size of the sample must be in a certain criteria such as precision level, confidence level, and the variability degree. In the case of sampling the attitudes…

Sampling Strategy and Sample Size for a Quantitative Research Plan Introduction When a researcher is constructing a sampling method, the questions about the population where the sample will come from and the size of the sample to be used come into play for the purpose of seeking statistical validity (Frankfort-Nachmias & Nachmias, 2008). Parahoo (2014) explains that, in order for sampling method or strategy to be considered credible, defining the population to be sampled, type of sampling,…

are limited in number possibly due to the nature of the researched issue or phenomenon. Similarly, a non probabilistic sampling orientation was adopted because the goal of the study is not to generalise to the population, but to obtain insights about a phenomenon by selecting individuals that will increase the understanding of that underlying phenomenon through a purposive sampling method (Onwuegbuzie and Collins, 2007, P.…

Public Opinion Surveys Public opinion surveys, or polls, are exactly what they sound like; a survey that asks the public their opinion on a topic. Polls are a form of inductive generalization because they gather information from a number of people and generalize their findings to cover the rest of the population. With that said, polls are used specifically for this purpose, which we can see in the media every day. One of the largest problems with the polls we see every day is that the details…

It was decided to use a non-probability sampling method. Even though this method is less valid, due to not having access to a sampling frame the probability sampling method could not be done and therefore, the only option was a non-probability sampling method. The non-probability method used was quota sampling; this is where the population is divided into subgroups by their characteristics, traits or a focused fact. Following this quota sampling; the questionnaires were handed out to fifteen…
