Based on the standard deviations and means across industries with respect to recognized variables, it can be argued that the technology and clothing sector have improved their financial performance over the last year. Note that the standard deviation of the technology sector is 1. 64 – a small variation from the mean. Note that the earnings per share of the same industry indicate an improvement. Note also that the mean returns on equity for both industries are 56. 58 and 18. 14 respectively with comparatively small deviations (using ratio).
