these participants had to have at least been on one practical placement. This allowed the research findings to be relevant to what the researchers wanted to find out. The target group can have an overall impact on the main findings. The nature of the sample that is used in qualitative research designs are clearly focussed to the question that is being asked (Burns, N & Grove, S 2007). Within this study convenience sampling is used, this is a non-probability method. Convenience sampling involves choosing

Analysis of a Quantitative Research Report This paper analyzes a quantitative research report selected because it focuses on enhancing patient education by attention to patient perceptions of the nurse educator. “Quantitative research is the formal, objective, systematic process used to describe variables, test relationships between them, and examine cause and effect interactions among variables” (Burns & Grove, 2007, p. 530). The report being analyzed is titled, “Nurses’ Body Size and Public Confidence

The social advantages of being fluent in more than one language are obvious: the more languages you speak, the more people you can communicate with. Another purported advantage of multilingualism is enhanced “executive function.” The term executive function is used to describe the advanced cognitive functions that define human mental abilities such as exercising self-control, attending to one specific stimulus, switching attention between stimuli, and planning future actions (Yong, 2016). There are

When nurses understand research, they can begin to implement changes that will benefit client care and outcomes. However, many nurses do not know how to read research studies and are unable to advocate for change in their practice. The purpose of this paper is to critically appraise a research article titled, Quasi-Experimental Evaluation of a Telephone-based Peer Support Intervention for Maternal Depression by Letourneau, N., et al. (2014) by evaluating and critiquing sections of the study. The

each condition of the experiment has a different group of subjects (McLeod, 2007). Often, one group of subjects undergoes the experimental treatment while the other undergoes a control condition. After the experiment is complete, an independent samples t-test is usually conducted to see if there is a statistical difference in the dependent variable(s) between the two groups. Subjects should be chosen at random. This is to ensure that each subject has the same likelihood of being assigned either

attachment. Strength and weaknesses: Niemann and Weiss (2012) decided to exclude four families who were unable to submit children’s cortisol samples, and this could further guarantee internal validity. However, regardless of the fact that this was a pilot study, the small sample size could negatively impact on external validity. In addition to the small sample size, it is potentially possible that these mothers, whether consciously or unconsciously, gave themselves and their children high scores during

interpretation of study results. In this paper, I will provide a summary of p value followed by explaining how (1) a huge sample size, (2) a homogeneous sample, and (3) heteroscedastic error terms in regression models can lead to a small p value and how to make good use of it. P values are used all over statistics. It is the probability of obtaining an effect at least as extreme as the one in the sample data, assuming the truth of the null hypothesis (Lew, 2012). It depends on a null hypothesis, the data, as well

Lab Report #1 Project Title: BCA Protein Assay Purpose: BCA (Bicinchoninic acid) Assay otherwise known as the "Smith Assay" has the fundamental purpose of determining the protein concentration of the two given unknown proteins in the sample solutions. The absorbance is measured using a Plate reader and a Standard curve is generated. Also, the different types of pipetting techniques are assessed in this Assay. Methods: (1) There are two methods using which the BCA Protein Assay can be

of treatment effect evidence, the imprecision assessment for relative importance of outcomes scrutinise the confidence interval and the sample size. What is challenging is because diversified study designs, result presentations or methodologies are used, usually there is no confidence interval constructed, or there is not a simple way to calculate the minimum sample size with sufficient power to produce a narrow estimate for the relative importance outcomes.[53] 3.4.1. Confidence interval 3.4.1.1.

The selection criteria were based on sticking to the key PICO words. Studies that involved both kids and adults were avoided, as the population being studied was strictly adults. Of the final 11 articles in PubMed, three RCT’s, and one SR/MA were selected. Two of those eleven were studying babies/children in conjunction with adults, so they were excluded. One study focused only on the prevention of CDI, and there was no mention of AAD, so that was eliminated in order to stick to the dependent
