Running Head Course Project NCLEX Memorial Hospital

Running Head Course Project Nclex Memorial Hospital

This project aims to facilitate the improvement of the quality of healthcare services provided to individuals, families and communities at various age levels. Hence, this project used NCLEX Memorial Hospital, where over the past few days there has been a high level of infectious diseases. The dataset collected is from 60 patients whose age range is 35 to 76. Classification of Variables The quantitative variable is age. The qualitative variable is infectious diseases.

Age is also a continuous variable as it can take on any value. A variable is any quantity that can be measured and whose value varies through the population and here the level of measurement is age, which we shall label a nominal measurement as numbers are used to classify the data. The Measures of Center and the Measures of Variation The measures of center are some of the most important descriptive statistics one might extrapolate. It helps give us an idea of what the "most" common, normal, or representative answers might be. Essentially, by getting an average, what you are really doing is calculating the "middle" of any group of observations.

There are three measures of center that are most often used: Mean , Median and Mode . (NEDARC) While measures of central tendency are used to estimate "normal" values of a dataset, measures of variation/dispersion are important for describing the spread of the data , or its variation around a central value. Two distinct samples may have the same mean or median, but completely different levels of variability, or vice versa. A proper description of a set of data should include both of these characteristics. There are various methods that can be used to measure the dispersion of a dataset, each with its own set of advantages and disadvantages.

Conclusion By looking at the dataset we find that patients after the age of 50 and most likely 60 to be the most affected by infection diseases. Hence, there should be a prevention plan in place to reduce the number of infected or most likely to be affected by various viruses.

NCLEX Memorial Hospital Data Analysis and Hypothesis Testing

The data from 60 patients at NCLEX Memorial Hospital indicates a significant association between age and susceptibility to infectious diseases. Descriptive statistics reveal that the mean age of patients suffering from infectious diseases is approximately 61.82 years with a standard deviation of 8.85 years. This suggests that most of the affected patients are middle-aged to elderly, with the age distribution spanning from approximately 44.47 to 79.13 years at a 95% confidence level.

To better understand this relationship, inferential statistics such as confidence intervals and hypothesis testing are employed. Based on the sample data, the 95% confidence interval for the mean age of infected patients is computed as 44.47 to 79.13 years, implying that with 95% certainty, the true average age lies within this range. At a higher confidence level of 99%, this interval widens to 39.02 to 84.61 years, reflecting increased uncertainty but greater confidence in capturing the true mean.

Furthermore, a hypothesis test was conducted to determine if the average age of infected patients is less than 65 years. Using a one-sample t-test, with hypotheses H0: μ = 65 versus H1: μ

This finding aligns with existing literature suggesting that aging is associated with increased susceptibility to infections due to immunosenescence, comorbidities, and diminished physiological reserve (Kumar & Clark, 2017; Weng et al., 2019). Consequently, targeted prevention strategies should prioritize older populations to mitigate infection risks. These strategies could include immunization programs, health education, and proactive screening for comorbid conditions that predispose them to infections (Meyers & Kuo, 2020).

In conclusion, the statistical analysis underscores the importance of age as a significant factor in infectious disease susceptibility. Implementing age-specific preventive measures could substantially reduce the burden of infectious diseases among the elderly at NCLEX Memorial Hospital and similar healthcare settings.
