In practice all calculators will give these results if the values of xi are keyed in. However, care must be taken that the correct key is pressed to obtain the standard deviation.
They can be combined to give an uncertainty in the final result, which provides a realistic range of values within which the true value of a measured quantity probably lies. This topic is dealt with in detail in Chapter 4. Bibliography The following books show the application of the statistical principles from this chapter in important areas of applied analytical chemistry. , 1991, Practical Statistics for Medical Research, Chapman & Hall, London.

295. From Eq. 05). Since the experimental value of ƒ t ƒ is greater than this, the difference between the two results is significant at the 5% level and the null hypothesis is rejected. 36, the difference is significant at the 1% level. In other words, if the null hypothesis is true the probability of such a large difference arising by chance is less than 1 in 100. The next example shows another application of this test, where it is used to decide whether a change in the conditions of an experiment affects the result.
