Page 1question 1 Tco A At An Outpatient Testing Center A Sample
Question 1. (TCO A) At an outpatient testing center, a sample of 20 days showed the following number of cardiograms done each day. a. Compute the mean, median, mode, and standard deviation, Q1, Q3, Min, and Max for the above sample data on number of cardiograms per day. b. In the context of this situation, interpret the Median, Q1, and Q3.
Paper For Above instruction
Analyzing the daily number of cardiograms performed at an outpatient testing center provides valuable insights into operational trends and resource allocation. In this context, calculating descriptive statistics such as mean, median, mode, standard deviation, quartiles, minimum, and maximum enables healthcare administrators to understand the distribution, variability, and central tendency of daily workload, which is essential for optimizing staffing and equipment use.
Firstly, computing the mean, which is the average number of cardiograms over the 20 days, gives a central value around which daily counts are dispersed. By summing all daily counts and dividing by 20, the mean provides a baseline for typical daily activity. However, the mean can be influenced by outliers; hence, median and mode offer additional measures of central tendency.
The median, the middle value when the data is ordered, indicates that half of the days had fewer cardiograms performed, and half had more. This measure is especially useful when data is skewed or contains outliers, providing a better sense of a "typical" day. The Q1 (first quartile) and Q3 (third quartile) values delineate the spread of the middle 50% of the data. Q1 signifies the 25th percentile, i.e., the value below which 25% of the days fall, while Q3 marks the 75th percentile, indicating the upper bound of the middle 50%.
Understanding the minimum and maximum values establishes the range of the data, highlighting the least and most active days. Standard deviation quantifies the dispersion of data around the mean; a smaller value indicates consistency among days, while a larger one signals variability. Mode identifies the most frequently occurring number of cardiograms per day, which can reflect common workload levels or sociodemographic factors influencing patient flow.
Interpreting these measures within the context of outpatient operations aids in planning for busy periods, identifying unusual days, and improving efficiency. For example, if the median is significantly different from the mean, it suggests skewness, possibly due to days with exceptionally high or low activity. Quartile analysis helps identify variability and identify outliers that could impact resource planning. Overall, these descriptive statistics serve as critical tools for data-driven decision-making in healthcare management.
