Nonprobability sampling

As of September 2016, over 260 million Americans have consumed at least 1 bag of potato chips. This means that at least 24375 tons of chips have been eaten in the past year. However, that calculation would only be true if each bag contained at minimum its labeled amount. When opening a bag of chips, it is easy to assume that the labeled amount is false due to the amount of empty space inside. Thus, the goal of this paper is to explore this idea and document the experimentation that follows in…

The foundation for this study was firmly based on the Factors Predicting the Use of Hazardous Drug Safety-Handling Precautions model. A model of the study (Figure 1) is provided for the reader’s educational purposes, and shows a relationship between the direct influences, such as employee’s level of experience and knowledge of the risks of choosing to not use proper protective devices, and indirect influences, such as influence from peers and managerial figures (p. E300). Overall, the…

Measuring validity is important because it determines the impact of research. Validity is defined as “an integrated, evaluative judgment of the degree to which empirical evidence and theoretical rationales support the adequacy and appropriateness of inferences and actions based on test scores or other modes of assessment” (Salkind, 2010, p.1). There are many criteria of rigorous research, for example, internal validity, external validity, objectivity of observer, replicability, and reliability…

When looking to get an overview on a topic, you don’t want to spend hours doing research; you want something quick and informative. You want your source of information to be quick to receive, and easy to understand. Above all, you want your information to be correct. This is why I think the documentary is a great resource for those who want to get an overview on what happened during the Holocaust. It is very easy to understand, and the information is delivered in a way that makes sense. It is…

The American Cancer Society has created a very powerful ad that has an effective layout as well. A good layout should be able to draw attention to the main point, have balance, clarity, and simplicity, which this ad has accomplished. This ad is very simple but effective because the main point of the ad is clear to the viewers. The ad is effective in the way of providing emphasis as well. Some ads can be scattered and have too many points trying to be portrayed, but with this ad, there is no room…

touches the political and socio-economic structures that a nation is built on. The study also revealed the general opinion of the public about what trading with others is like to them. First, the study employed a rather straight-forward methodology and sampling design. It should be noted that a structured questionnaire was administered through randomly selected telephone lines to people who have attained…

will use the nominal and ordinal scales to measure the dependent and independent variables. It will also include dichotomous questions. Sampling: My target population and the sampling frame are children ages twelve to eighteen, in grades sixth through twelfth grade, which are in disadvantaged environments, according to the United States Census. Probability sampling will be used so that it can be known in advance how likely it is that certain element of the population will be selected for the…

Another aspect that remains open for criticism is if the author should have taken a cross-methodical approach and thus included a document review in his data acquisition. Millar describes that his original approach was to review video footage from the TRC hearings and then conduct interviews based on them. However he ultimately chose not to include these archival sources, as he found them to be insignificant to the local population (Millar 2010: 484-485). However the analysis of such material…

Building on this research, one could vary the data by including more high school students from different backgrounds and socioeconomic statuses. Finding out how these factors contribute to the number of AP classes taken and cumulative GPA will increase the effectiveness of this observational study. The limitation of the research was that many of the students who took the survey were from Ms. Moneypenny’s AP Statistics class, and other AP classes, as listed in the Introduction. This gave the data…
