Public Health Canada has issued a recall of a particular orthopedic implant. All facilities are requested to provide information on the number of patients receiving this implant over the last 5 years, aggregated by fiscal year. You would use:

A frequency distribution is a statistical tool used to organize and summarize data, particularly for categorical variables or data over defined intervals. In this scenario, Public Health Canada is requesting the number of patients who received a specific orthopedic implant over the past five years, broken down by fiscal year. Utilizing a frequency distribution would effectively present this data in a clear and organized manner, showing the count of cases for each year, which helps in understanding trends over time.

This method allows health information professionals to provide a comprehensive overview of the implant's usage, facilitating analysis of its prevalence and enabling quick identification of trends or anomalies in the data. The structured format of a frequency distribution makes it easy for stakeholders to interpret the data, which is crucial for effective decision-making following a recall.

While other options, such as a pie chart, may display proportions of data visually, they do not lend themselves as well to showing counts over intervals like fiscal years. Measures of association and t-tests pertain to analyses of relationships between variables or group comparisons, rather than summarizing counts within a defined timeframe. Thus, a frequency distribution is the most appropriate choice for presenting the requested information.
