1 2 52 100 STATISTICAL TESTS A combined test can be obtained using the test statistic χ = 2 K3 n × 3 6 (K2 ) 2 1 2 2 + K4 n × 2 24 (K2 ) 1 2 2 which will approximately follow a χ 2 -distribution with two degrees of freedom. Example Example A A large sample of 190 component measurements yields the following calculations (see table). Do the sample data follow a normal distribution? 96. Since u1 is less than this critical value we do not reject the null hypothesis of no difference. So for skewness the data are similar to a normal distribution.

Has the variability of the volume of fluid injected changed? 42. So we do not reject the null hypothesis of no difference. This means that we can still consider the variability to be set as required. 42 [Table 5]. 05 Do not reject the null hypothesis. The difference between the variances is not significant. THE TESTS 45 Test 16 F -test for two population variances (variance ratio test) Object To investigate the significance of the difference between two population variances. Limitations The two populations should both follow normal distributions.

Xn , the test statistic r where r r r r = (x2 − x1 )/(xn − x1 ) = (x2 − x1 )/(xn−1 − x1 ) = (x3 − x1 )/(xn−1 − x1 ) = (x3 − x1 )/(xn−2 − x1 ) if if if if 3 < n 7, 8 n 10, 11 n 13, 14 n 25. Critical values for r can be obtained from Table 8. The null hypothesis that the outlier belongs to the sample is rejected if the observed value of r exceeds the critical value. Example As part of a quality control programmed/implementation small samples are taken, at regular intervals, for a number of processes.
