In Willems et al’s study of proprioception deficits among athletes with high rates of recurring lateral ankle sprains, they found that almost all of their subjects tended to under shoot the needed ankle during the test (Willems et al., 2002). In this study they had 4 groups of athletes to study. The control group were individuals who had no prior ankle injuries (Willems et al., 2002). The Instability group were individuals that had suffered from more than three inversion sprains and complained…

Growing up in the United States is not the same every child. Some parents expect more out of their children than others. The Academic article “The duty to succeed: honor versus happiness in college and career choices of East Asian students in the United States” written by, Lauren Dundes, Eunice Cho and Spencer Kwak tests the hypothesis that parents from East Asian decent are harder on their kids and expect more out of them compared to white parents. The article was written for college…

each domain will be selected according to the distribution of the threshold values across the latent scale and the discrimination value; item that has threshold values cross the whole latent scale and high discrimination value will be selected. Sample Size Graded response IRT model requires 250 subjects to be estimated. However, approximately 500 subjects are recommended to get more accurate estimation of the model parameters [56]. We have more than 500 subject in the database that we are…

According to the course text, here are many strengths and weakness of field research. These strengths and weakness include: validity, reliability, and generalizability. Conducting field studies of behavior is more appropriate than trying to measure behavior through surveys. For example, the counts of seatbelts use or theft by shoppers obtain through observation are not subject to the effects of social desirability that we may expect in survey questions about those specific behaviors. Next,…

a) Sample selection size varies for each experiment, depending on how large the whole group under investigation is or how much time it would take to sample a certain group (Rathburn, MacConnadchie, Zizler, Hill, & Moorman, 2012, p. 72) . Sample selection is important part of a studies experimental design because it usually decides how valid a study is. The validity of the sample size and study is usually decided through the peer-review process, which is one of the reasons why the peer review…

1. “When investigating a large population, it is often impractical and usually unnecessary to measure all the elements in the population of interest. Typically, a relatively small number of subject or cases is selected from the larger population.” (McMillian, 2012, p.96) According to McMillian (2012), population is a target you want to study to develop knowledge and to create action plans to assist those individuals. An example is when a researcher use a group of students with autism to find out…

a) The sample size in this survey should be large enough so that it can encompass the whole population. The sample size if too small can lead to misleading and inaccurate conclusions. The more people surveyed the more accurate the representation of the general population will be. b) 3% is an excellent random sampling because out of 17,000 people 3% would be 500 people, which is a fairly large sample size. c) The margin of era is .045 and the sample proportion…

Vincristine is the primary treatment for acute lymphoblastic leukemia (ALL) in children. Common toxicities include peripheral and autonomic neuropathies, which can be life threatening. Vincristine is metabolized extensively by CYP450 3A and its PK has a significant inter-individual variation. In addition to chemotherapy treatment, children are given antifungals for prophylaxis of infections. Itraconazole, voriconazole and fluconazole are commonly used agents. The azole family is an inhibitor of…

North Andaman Islands (NAI) are one of the major island groups of Andaman and Nicobar archipelagos (Fig.1), consisting tropical rainforest encompassing varied species richness and diversity coupled with high endemism (Prasad et al..). As per Champion and Seth [year] the predominant forest types of the study area are Andaman Evergreen (EG), Andaman Semi-evergreen (SEG), Andaman Moist deciduous (MD), Littoral and Mangrove forests. Major part of the island is covered with SEG which is scattered at…

of these studies attempt to prove causation, it is impossible with a correlational design method. Regardless of a positive or negative correlation, it cannot be used to prove causation. In several of the studies there is a small sample size, or even a sample size that is not indicative of the entire population. Additionally there is no knowledge of whether or not the studies used a double blind technique. If a double blind technique is used there is no researcher bias. Without this technique the…
