Research Methods - past exam paper - Assignment Example He explained that variance process explains the relationship between the dependant and independent variables leading to an outcome while the process theory explains the patterns of events that led to the outcome of an event. Selection bias is the process of selecting group of objects or individuals in a manner so that the selected sample does not represent a particular segment of population. In such a case, the estimated sample would be biased in nature due to random approach of selecting the sample size. Selection bias is likely to occur more commonly as a result of the random sampling method. The given summary statistics could be used to interpret and compare the average scores of the class in the two tests and also comment on the dispersion of the scores from their average scores, the comparison among the highest and lowest scores in those two tests. The mean values suggest that average score for Test2 is more than Test1. The standard deviation shows that more number of students has variation from average score in Test1 as compared to that in Test2. The median suggests that the mid-point score for all students arranged in ascending order for both the tests is same. The 1st quartile shows that the lowest score for the two tests are different while the 3rd quartile shows that highest score is same for both the tests. Analysis of Variance (ANOVA) is a statistical method that could be used to test the relative dispersion among the variables captured by the researcher. As the measurement units are different, the data set may not follow normal distribution. For this reason, ANOVA method would be useful for testing the relative dispersion among variables. Sample distribution is the statistical distribution of a random variable selected from a sample size in a random manner out of the entire population. It is said to be normally distributed when the mean, median, mode are all equal and the

Heritage Valley Medical Center Assignment Example | Topics and Well Written Essays - 1000 words

Heritage Valley Medical Center - Assignment Example In the past, Heritage Valley Medical Center was a very successful medical facility, serving all its patients with dignity and equality to an extent that both the community and the staff of the facility were completely satisfied with the services. However, this has changed over time, with the introduction of a change in the medical policy that allowed more minority population to access the services offered by the facility. This change saw the community patient ratios change from the initial 80% Caucasian, 15% African American, and 5% Hispanic, to a new ratio of 50% Caucasian, 40% African, and 10% Hispanic. With this change, the financial capacity of the medical center has gown down, since the increase in the minority community patients means a reduction in private pay patients and thus money paid for the medical services (Buchbinder & Thompson, 2010). However, the ethnic composition of the health medical center staff did not change, having the facilities team dominated by the Caucasian medical professionals, while the African Americans dominated the support and the administrative staff segment of the facility. The Hispanic community was barely represented, having just one manager in the entire team. The whole executive team was dominated by Caucasians who made a 100% of the team members. There was a good cooperation between the staff of the facilities, until a report regarding the satisfaction of the communities with the facility services was discussed at a meeting. During the meeting, it became apparent that the minorities were not satisfied with the services. ... This indicates that the facility staff composition has not put gender balance policy in place (Buchbinder & Thompson, 2010). Another issue identifiable in this case is the lack of diversity in the staff composition under some segments. While the executive and the medical professional segments are represented by the Caucasian predominantly, the administrative and support staff segment is represented by the African Americans. The Hispanics do not seem to have any representation in the staff team. This is a clear indication that there lacks diversity in the staff team (Buchbinder & Thompson, 2010). Cultural value disrespect is yet another issue that is apparent in this case. The Caucasian staffs do not seem to value the cultures of other communities, especially the minority communities. They regard the language of other communities as intolerable, while perceiving the accompanying of minority patients by their family members into the facility as uncivilized. The African Americans on the other hand do not seem to be proud of their culture, and they disregard the cultures of the Hispanics and the Asians, arguing they need to learn how to speak in English. Language barrier is yet another issue observable in the case, where the patients and the staffs do not seem to understand each other when they are communicating (Buchbinder & Thompson, 2010). The nurses argue that they cannot understand the language spoken by the Asians and the Africans, and as such, they may not be able to serve their needs appropriately. Nepotism is yet another issue identified in the case, where the Caucasian community patients seems satisfied with the services offered by the medical center, while the other
