Sample size

The two-sample t procedure is appropriate to use in this experiment in order to see if there is a difference in the two population means of stride length in the two different species, N. rattus and N. squamipes. This is because the boxplots appear to be roughly symmetrical, as well as, both normal quantile-quantile plots look roughly linear. Considering two-sample t-procedures are quite robust to violations of the normality assumption, the t-procedure will likely perform well in this…

Stress Management App Efficacy: The Impact on Negative and Positive Affect Do various stress management apps effect negative and positive affect differently? The present study consisted of a randomized comparative efficacy trial, which aimed to unveil whether three stress management applications differed in their impact on negative and positive affect. Participants completed a pre-test assessment of their experiences of various negative and positive affects. The pre-test assessment also…

primary care doctor intervention, and family dynamics in the complex progression of hospice care. Researchers did acknowledge that improved communication could prevent readmission. The study should be replicated and expanded to reflect a larger sample size and patient/family perceptions of hospice care. The authors note the statistical insignificance of the study, but bring up potential measures for future research regarding the topic. Application to Nursing Practice The study is limited in…

With the innovations of the 21st century and its continuous development, young adults have much more benefits than our grandparents or even parents have ever had in terms of easy information access, exchange of ideas and thoughts with a large public, and communication with those who are physically far away from us. Additionally, devices that permit transmission of instant messaging and texts became a large part of the youth’s interaction in everyday life (Luo & Tuney, 2015, p.671). Some of them…

Introduction: Coffee is a popular ubiquitous beverage in the daily life of an undergraduate student. For many it is a habit that gradually forms and stays. Its popularity lies in the key ingredient, caffeine, which decreases fatigue and instead increases alertness, features that aid an undergraduate student 's academic performance when studying on little sleep and going through the day (Giles et al., 2012). However, besides coffee 's use as a stimulant, can it be used to influence cognitive…

Others were: farming experience (measured number of years in farming), beekeeping experience (recorded in years), non-farm income (measured as binary response on availability of other non-farm income on the farm (if yes =1, otherwise = 0), and household size (given by the number of household members). Also included…

The research done on the Suicidal Ideation Questionnaire used a sample of 35 adolescents (Boege et al., p.2). When compared to the sample 180 adolescents used in the research of the Multi-Attitude Suicide Tendency Scale, this number is relatively small (Osman et al., 2000, p.378). A problem that arises when using a small sample size is the generalizability of the study. When considering just this, the information gathered on the Suicidal Ideation…

3. Literature Review: In our paper we used three ways to get the leaf classification, one that was Random Forest, the other being Naïve Bayes and the third being Keras which is also known as Neural Networks. There have been many other cases like ours that have used Random Forest. Nantian Huang, Guobo Lu and Dianguo Xu have been one of the many who have used Random Forest and succeeded. In their paper, “A permutation importance based feature selection method for short term electricity load…

Overview Change Article The change article by Grant (2014), has been chosen for its in-depth psychological analyses of a predominantly human resource (HR) issue; executive coaching. It parades an analysis of executive coaching in times of change that eventuates into an opinionated, yet empirical outcome. Grant (2014) hypothesises that executives undergoing coaching, deliver on organisational goals more frequently. This is supported by a research case study that concludes building effective…
