This report presents a comprehensive statistical analysis of call center employee data from two locations. The analysis investigates relationships between variables such as original vs. replacement staff, median call time, the proportion of calls exceeding 3 minutes, and the number of complaints. Descriptive statistics, including averages, percentages, and correlations, are calculated to compare the performance of original and replacement staff across the two call centers. Furthermore, the report utilizes inferential statistics, including t-tests and confidence intervals, to determine the significance of differences in median call times and proportions. Scatter plots are used to visualize the relationship between median call time and the number of complaints. The findings indicate that original employees tend to have higher median call times and a greater proportion of calls exceeding 3 minutes compared to replacement employees. Moreover, a positive correlation is observed between median call time and the number of complaints. The report concludes by highlighting the significant differences in performance between original and replacement staff, providing valuable insights for management to make informed decisions.
