| Abstract The existence of extreme values leads to a great confusion in analyzing data in case of using the traditional methods for evaluation and one of these methods is the least square method. Thus, it was resorted to the analyzing of data by excluding the extreme values and their comparison with the complete data analysis. The extreme values were treated in data by two ways: the first is increasing the size of the sample for other years where this sample becomes suitable for evaluation as in the original data analysis after excluding the extreme values. While the second way is to use the inaccessible methods in discovering, evaluating and comparing the two ways with each other concerning the accuracy. All this was applied on the data of electric power gaps Mw for all the sectors in Nineveh governorate for the period (2004 – 2007). We concluded the importance of the two ways and each one depends on saving data, and the accuracy meter assured that the size of the large sample gives the most accurate results for the study since the sample represents the society in the best way. | ||
