Similarly the first quartile can be defined as 1/4 of the way through the sorted data, and the third quartile to be 3/4 of the way through the sorted data. Second quartile is also known as the median. The range between the first and third quartiles includes half of the data. The size of the range (i.e., the difference between the third quartile and the first quartile) is another measurement of variability called the inter-quartile range or IQR. For normally distributed data: IQR = 1.35 From the above calculations it appears the reorganization exercise has not been a grand success. Though it appears to have tightened some loose ends but still the average output remains the same.

The size of the range (i.e., the difference between the third quartile and the first quartile) is another measurement of variability called the inter-quartile range or IQR. For normally distributed data: Taking a look at the mean, median figures of the production efficiency 'before' and 'after' the implementation of these steps, it is quite apparent that the consultants have not been able to improve the assembly line as much as desired by the company.
