Blood samples following instillation of 2 drops of polymyxin B 10,000 units/ml and trimethoprim 1 mg/ml in the eye resulted in peak plasma concentrations of polymyxin B and trimethoprim of 1 unit/ml and 0.03 mcg/ml, respectively.
An Alternative Definition for IQR. In some texts, the interquartile range is defined differently. It is defined as the difference between the largest and smallest values in the middle 50% of a set of data.To compute an interquartile range using this definition, first remove observations from the lower quartile.Then, remove observations from the upper quartile. Then, from the remaining observations, compute the difference between the largest and smallest values.n Alternative Definition for IQR. In some texts, the interquartile range is defined differently.

The interquartile range is a value that is the difference between the upper quartile value and the lower quartile value. Coach Taylor can use the interquartile range to summarize the overall accuracy of his players. To find the quartiles of this data set use the following steps: 1  Order the data from least to greatest. 2  Find the median of the data set and divide the data set into two halves. 3  Find the median of the two halves.
