In this paper, I will demonstrate how to analyze audit data by constructing a frequency distribution in Excel, following instructions outlined in Chapter 2 of the textbook, and develop a comprehensive figure that includes frequency, relative frequency, and cumulative frequency. This process allows a clear understanding of data distribution, which is essential for audit analysis and decision-making. The steps involved include data organization, creating the frequency table, calculating relative and cumulative frequencies, and plotting the figure.

Introduction

Audit time data plays a vital role in auditing processes as it helps auditors understand the distribution and variation in audit durations. Analyzing this data via frequency distributions allows auditors to identify patterns, outliers, and trends that could influence audit planning and resource allocation (Arauz, 2018). The instructional focus involves using Excel to construct a frequency distribution, enhance it by adding relative and cumulative frequencies, and develop a precise figure (chart) that visually summarizes this information.

Data Organization and Preliminary Steps

The first step involves obtaining the audit data file, which contains individual audit times. Once downloaded, the data needs to be reviewed for completeness and accuracy. The audit times will be organized into classes or intervals—commonly known as bins—based on the range of data, ensuring that each class covers an equal interval (e.g., 0-10 hours, 11-20 hours, etc.). The choice of class width depends on the spread of the data and aims to balance detail with clarity (Ott & Longnecker, 2015).

Constructing the Frequency Distribution

Using Excel, the data is sorted, and classes are created. For each class, the frequency—i.e., the count of audit times falling within that interval—is calculated with the COUNTIFS function or by using Excel's Histogram tool (Microsoft Support, 2021). For example, if using 10-hour intervals, the number of audit times between 0-10 hours, 11-20 hours, and so forth, are counted and listed in the frequency table.

Calculating Relative and Cumulative Frequencies

Once frequency counts are established, the relative frequency for each class is calculated by dividing the class frequency by the total number of observations (N). This results in a proportion that indicates the relative standing of each class within the entire dataset (Everitt & Skrondal, 2010). Subsequently, the cumulative frequency is computed by successively adding each class's frequency to the total of all previous classes, providing insight into the cumulative data at each interval point.

Developing the Figure (Chart) in Excel

To create the figure, Excel's Chart tools are employed. The chart should include classes on the X-axis and the counts (frequency), relative frequency, and cumulative frequency on the Y-axis, preferably using a combination of bar and line charts for clarity. For instance, the bar graph can depict the frequency distribution, while lines overlay to show cumulative and relative frequencies—facilitating comparative analysis (Cleveland, 1993).

Presentation and Interpretation

The final figure should be neatly labeled with axes titles, a descriptive legend, and title for clarity. Analyzing this chart helps understand which audit durations are most common and how the data accumulates over classes. Such insights assist audit teams in planning and resource allocation, addressing outliers, and improving efficiency.

Conclusion

Constructing a frequency distribution with additional relative and cumulative frequencies using Excel offers a powerful method for auditing data analysis. It transforms raw data into an accessible visual format that enhances understanding of data patterns. Following the systematic steps—from data organization to chart development—ensures an accurate and insightful presentation of audit time distributions, supporting better managerial and operational decisions.
