How are the industry metrics calculated?
The calculation of industry indices involves two steps. The first is filtering the individual industry data for anomalies and the second is to create descriptive statistics (quartile values) for the industry. A subset of the quartile calculation involves defining small versus large firms within an industry. After the data are filtered for anomalies, firms are divided into groups based on median sales volume. Those firms above the median are defined as large, while those below are small. These values appear with the statistics for the entire industry (all). Future enhancements will allow users to specify the criteria for defining small versus large. This will allow them to sort the data by any of the denominators presented.
