Calculate All Statistical Data For The Total
Calculate all statistical data for the Total
Analyze the provided data regarding various skill types and their associated performance metrics, including Number of Calls (NCO), Number of Calls Handled (NCH), Number of Calls Abandoned (NCA), percentage of Calls Abandoned (%NCA), Service Level, Average Speed of Answer (ASA), Average Handle Time (AHT), After Call Work (ACW), Max Delay, and other relevant statistics.
Without rearranging, moving rows, or deleting data, compute the overall totals for these metrics across all listed skill types. Focus on the highlighted area, primarily the total values, and demonstrate the calculation process by showing how each total was derived through summation or other appropriate aggregation techniques. Ensure to include the following:
- Total NCO, NCH, NCA
- Overall %NCA calculated as (Total NCA / Total NCO) * 100
- Aggregate Service Level, ASA, AHT, ACW, Max Delay, and other metrics as weighted averages or sums as appropriate

Analyzing call center performance data across different skill types necessitates comprehensive aggregation to understand overall operational efficiencies and challenges within the organization. This process involves summing the total number of calls (NCO), handling the total calls handled (NCH), and counting the total abandoned calls (NCA). From these totals, the abandonment percentage (%NCA) can be computed to evaluate customer service quality and identify areas requiring improvement.
The dataset provided includes various metrics, some of which are averages or percentages, such as Service Level, ASA, and AHT. To accurately assess total performance, these figures must be calculated as weighted averages, giving prominence to the relative volume of calls handled in each skill category. For example, the overall Service Level is derived by multiplying each skill's Service Level by its proportion of total calls, then summing these. Similarly, ASA, AHT, and ACW are averaged based on call volume, ensuring the aggregate reflects the entire dataset's characteristics.
Calculations begin with the summation of raw counts: adding all NCOs across the skill types provides the total calls initiated. Likewise, summing NCHs gives the total handled, and aggregating NCA yields total abandoned calls. The overall abandonment rate is then calculated as total NCA divided by total NCO, multiplied by 100 for percentage clarity. These totals produce a comprehensive picture of call traffic and abandonment rates, crucial for operational decision-making.
Furthermore, metrics like Max Delay and AHT are best represented through weighted averages, considering the call volume of each skill. For example, if one skill category has significantly more calls, its service level and handling time will influence the totals more heavily. Such calculations enable a more accurate understanding than simple averages, particularly when different skills serve diverse customer needs and operational contexts.
Ultimately, data aggregation facilitates strategic improvements by highlighting where inefficiencies or high abandonment rates occur. It also allows comparison across different skill groups to identify best practices and areas requiring resource reallocation. Proper calculation and interpretation of these overall metrics are vital steps in leveraging call center data for enhanced service quality and customer satisfaction.
