Critical analysis is defined as a systematic evaluation utilized to recognise the strengths and weaknesses of a scientific article in order to assess the usefulness and validity of research results.1,2 It is an essential skills that all researchers should have in order to distinguish deceptive information and filter out any low-quality research.3 The purpose of this paper is to critically analyze a scientific research article entitled “Time to manage: patient strategies for coping with an…

“Good design goes to heaven. Bad design goes everywhere.” – Mieke Gerritzen. This quote beautifully captures just how difficult it can be to create a solid research study. There are an incredible amount of things to consider when crafting a strong design and when it is done well there are numerous benefits. However, when it is does not go according to plan the intended outcomes crumble like a house of cards. The research study Predicting Adjustment During the Transition to College, had many…

ensure that all homophobic language and actions are challenged and eliminated. Although, this research project did not analyse the data collected from the questionnaires, it can be argued that the small sample size (one student teacher) has significant limitations on the results. A bigger sample size would allow for better understanding of the issues of teacher preparedness to address issues of homophobia within the school. Furthermore, only using quantitative data has its own implications, due…

significant impact on the depressive symptoms. There was no mixed finding on the effectiveness of music therapy to manage depression regardless of intervention type, duration, or intensity. However, in the future reviews randomized trails using a larger sample size are required to increase the consistency of study results, thereby maximizing the external validity in order to generalize study…

Beltway Shoe Company Statistics are everywhere, in business meetings in the form of graphs and charts, quality in the form of frequency of errors, and in the media as survey results and weather forecasts. Some folks may be nervous when they hear the word statistics; however, they are most likely using statistics and probability nearly every day of their life and not even notice it. Beltway Shoe Company is featured in this exercise reviewing the results of their Western and Eastern region shoe…

for future research. Additional research is required to determine effective noise reduction interventions, although Caitlin et al. (2008) did find that earplugs improved both patient and staff satisfaction. A majority of the studies had insufficient sample sizes that limit generalizability of the…

Pre-Lab Questions 1. A population is a group of the same species that live in the same area and sometimes compete or can mutually benefit one another. A group of organisms will only be considered a population if they live in the same area in space and time. N is the true population size for a given group of organisms. This number is unlikely to be completely known. Whereas N hat is an estimate of population size. 2. There are two methods of sampling, direct and indirect. Direct sampling is an…

Article Critique Anorexia is a classless, ageless, and genderless psychiatric disease that affects people all over the world. In the majority of the cases, it develops during adolescence a period of change an instability where proper guidance should be given.This study looked at inpatient treatment intervention (IP) versus a day patient treatment intervention (DP) on adolescents. The article’s title is self explanatory and just a few adjustments are needed for clarification to readers…

appropriate sample size, several factors were considered. These factors included important data elements such as quality, scope and the complexity of the data. A multidisciplinary research team was used in order to ensure rigor and accuracy of the conceptual…

when the sample size is large enough n>30, the population standard deviation is known, and population is normally distributed. Example: Is the mean of systolic blood pressure level for women use of oral contraceptives is identical with women does not use of oral contraceptives, the sample mean > 30, we known the population standard deviation and it is normally distributed. H0: µ1=µ2 H1: µ1≠µ2 2. t- test is used when the population standard deviation is not known, the sample…
