Your Organization Collects Data On Individual Patients

2 1 Your Organization Collects Data On Individual Patients Shown In A

Your organization collects data on individual patients shown in Appendix Table 2. Identify whether each variable is measured nominally, ordinally, or as an interval/ratio variable. The Variables are Gender, Age, Convenience Satisfaction, Insurer, Same Day Appointment, Rx Coverage, and Co-pay.

What statistical measures would you use to summarize the variable for age? What about for gender? For convenience satisfaction? How would you present these graphically?

If you are interested in whether satisfaction scoring differed by the amount the individual paid as a co-pay, how would you state this inquiry as a testable hypothesis (the null and alternative)? What statistical test would you run to test this hypothesis?

Paper For Above instruction

In the realm of healthcare research, understanding the measurement levels of various patient data variables is foundational for selecting appropriate statistical analyses. The variables collected by the organization—namely Gender, Age, Convenience Satisfaction, Insurer, Same Day Appointment, Rx Coverage, and Co-pay—each possess distinct measurement scales that influence how they can be analyzed and interpreted.

Measurement Levels of Variables

Gender is a nominal variable because it categorizes patients into distinct groups without any inherent order, typically male, female, or other categories. Age is an interval/ratio variable since it represents measurable quantities with a true zero point, allowing for calculations of means or differences. Convenience Satisfaction is an ordinal variable because it often involves rankings or ratings (e.g., on a Likert scale from 1 to 5), indicating order but not equal intervals between categories. Insurer is nominal, categorizing patients by their insurance provider. Same Day Appointment and Rx Coverage are nominal variables representing yes/no responses, indicating the presence or absence of these features, thus categorizing patients without order. Co-pay, representing the amount paid by the patient, is an interval/ratio variable because it is a measurable amount with a numeric value allowing for mathematical operations.

Statistical Summaries and Graphical Presentations

To summarize the age variable, descriptive statistics such as the mean, median, standard deviation, and interquartile range are appropriate, given its interval/ratio nature. These measures provide insights into central tendency and variability. For gender, which is nominal, the suitable summary statistic is frequency counts and percentages. Graphically, a histogram or boxplot can visually depict age distribution, showcasing its spread and central tendency. For gender, a bar chart or pie chart effectively displays the proportion of each category. Convenience Satisfaction, an ordinal variable, can be summarized using median and mode, with frequencies also informing the most common ratings. A bar chart or stacked bar chart can illustrate satisfaction levels across the patient cohort, depicting the distribution of ratings.

Testing the Relationship Between Satisfaction and Co-pay

If the organization aims to investigate whether patient satisfaction scores differ based on the amount paid as a co-pay, this research question can be formalized as a hypothesis test. The null hypothesis (H0) posits that there is no difference in satisfaction scores across different levels or ranges of co-pay amounts. Conversely, the alternative hypothesis (H1) suggests that satisfaction scores do vary with the amount paid as a co-pay.

Given that satisfaction scores are typically ordinal or interval data and co-pay amounts are continuous, the appropriate statistical test could be an ANOVA if co-pay is categorized into groups, or a correlation analysis if using continuous measures. Specifically, if co-pay is divided into meaningful categories (e.g., low, medium, high), a one-way ANOVA would test for differences in mean satisfaction across these groups. If the co-pay is continuous, a correlation or linear regression analysis can examine the relationship between co-pay amount and satisfaction scores.

This hypothesis testing assists in understanding whether the financial burden influences patient satisfaction, guiding policy and operational decisions to enhance patient experiences.
