Sample size

Salt marshes are found amid human developments and coastal areas and play an important role in protecting these communities from the threats posed by being close to the coast. Depending on the density of vegetation, production of biomass, and the size of the marsh, salt marshes provide many critical ecosystem services, such as, stabilization of the shoreline, weakening of the waves, and reduction of floodwater (Shepard et. al. 2011). Wetlands include boreal peatlands and tropical mangroves.

particular application a client gave Quality Associates a sample of 800 observations taken during a time in which the client’s process was operating satisfactorily. The sample standard deviation of this data was 0.21; hence with so much data, the population standard deviation was assumed to be 0.21. Quality Associates then suggested that random samples of size 30 be taken periodically to monitor the process on an ongoing basis. By analyzing the new samples, the client could quickly learn whether the process

In performing a parametric test, it is essential to know if the data is normally distributed. Furthermore, we may have to determine to perform a nonparametric test. Thirdly, how many samples are involved? Such as, were there one, two, or three or more samples. And lastly, if we are utilizing two or more samples are the cases related

noted that several patients postoperatively provided positive feedback on music therapy and increased their comfort level. Analysis of Study Two There were a few limitations in this study one of them being that the study was conducted on a small sample size consisting of 30 women therefore, the results cannot be applied to all women who may be suffering for breast cancer or any cancer for that matter (Binns-Turner et al., 2011). Furthermore, the results can only pertain to women, and not men who may

In future studies, the sample should be drawn from more than one university, and that a larger sample size should be used as well. In 2006, Rothwell and Theodore explored the relationship between participation in intramural sports and value clarification among college students. Convenience sampling was used to help

The methods of this research article is strong because of the data analysis used. However, this was a short section in the paper. It only included three paragraphs, which is not nearly enough to cover all of the content of an eight-page paper. Although it was short, this article was convincing of the data provided (Batista et al., 2017). Protection of participants’ rights. In order to protect the rights of the participants, the study did a decent job in attaining consent. The participants were to

Our root node, which holds 100% of the sample, and average sleeping hour for mammals in the entire sample is 10.4 hours. Then, our decision tree diverges to left (for condition being true, that is, is body weight equal to or greater than 168?) One thing the data scientist should always to is to get an assessment of how the chosen algorithm is performing, as far as accuracy is concerned. Different packages and different methods often use different algorithms and it is important to understand how source
