In the context of communicable diseases, understanding patient demographics is vital for tailoring effective treatment strategies. At NCLEX Memorial Hospital, the recent uptick in admissions related to a specific infectious disease has raised concerns among healthcare providers and administrators. A critical aspect of this investigation involves analyzing the age distribution of these patients to determine if age influences disease susceptibility, severity, or treatment outcomes. This analysis not only aids in clinical decision-making but also informs preventive strategies and resource allocation.

The primary variables in the dataset include patient identification number, infection disease status, and age of the patient. The infection disease status indicates whether the patient has been diagnosed with the infectious disease under study. For analytical clarity, comparing the ages of infected and non-infected patients can reveal significant insights about disease vulnerability across different age groups.

To initiate the analysis, descriptive statistics such as the mean, median, mode, range, standard deviation, and variance of patient ages are calculated. These measures provide a foundational understanding of the age distribution within the patient population. For example, the mean age offers an average age, while the median indicates the middle point, useful in skewed distributions. The mode reveals the most frequently occurring age, and the range shows the spread between the youngest and oldest patients. Standard deviation and variance quantify variability, indicating how dispersed the ages are around the mean.

Calculations are performed within the attached Excel spreadsheet, ensuring accuracy and transparency. The spreadsheet includes formulas for each statistical measure, which are then interpreted to understand the general age profile of the patient cohort. For instance, a high standard deviation suggests considerable age diversity, potentially affecting treatment approaches.

Following descriptive statistics, we construct a 95% confidence interval for the mean age of patients. This interval estimates the range within which the true population mean age likely falls with 95% confidence. The calculation incorporates the sample mean, standard error, and the critical value from the t-distribution, taking into account degrees of freedom based on the sample size. Interpreting this confidence interval provides clinical insights—for example, confirming whether the average patient age is within a specific age bracket that might influence treatment protocols.

Next, a full hypothesis test assesses whether there is a significant difference in the mean ages between infected and non-infected patients. The null hypothesis states no difference exists, while the alternative hypothesis suggests a difference. We use a two-sample t-test for independent samples, calculating the test statistic from the sample means, variances, and sizes. The resulting p-value indicates whether to reject the null hypothesis. A p-value less than 0.05 signifies a statistically significant difference, implying age could be a factor in disease susceptibility or progression.

In conclusion, this analysis offers valuable insights into the age-related patterns of infectious disease cases at NCLEX Memorial Hospital. Understanding whether significant age differences exist among patients can guide targeted interventions, optimize resource deployment, and reinforce preventative measures for vulnerable age groups. The statistical findings, including descriptive measures, confidence intervals, and hypothesis testing results, provide a comprehensive understanding of the role of age in this disease outbreak.
