2.5.8. Statistical Analysis

All tests have been performed by taking the average of three (samples) readings. The standard error of the mean was calculated according to the equation given below and found to be + (−) 0.1

$$\mathbf{S} \mathbf{E} \mathbf{X} = \mathbf{S} / \sqrt{\mathbf{n}}$$

where S = sample standard deviation, and n = the number of observations of the sample
