Both measurements shown in Table 4.2 is repeated for about 10 times, would the standard deviations of the measurements be considered significantly different from each other or not has to be identified. Concept Introduction: The significant difference in standard deviations is determined by using F test. If calculated F value is greater than Table F value with number of trials – 1 degrees of freedom the standard deviations are considered as significantly different.
