Student-Newman-Keuls test

FIGURE 5.8 Bioavailability of 60-mg CoQio single dosing (early absorption). AUCo 4 h (pmol/mmol x h) after a single dose of 60-mg CoQiq. Data are expressed as mean SD. Differences between formulations were tested with ANOVA and post hoc test Student-Newman-Keuls test. p < 0.05 (both solubilizates vs oily dispersion 1 and oily dispersion 2 vs crystalline) p < 0.01 (both solubilizates vs crystalline). 

When the ANOVA shows that the means are not equal, there are several post hoc that can be used to determine where the differences lie, such as the Tukey or the Student-Newman-Keuls test. However, the use of these tests is beyond the scope of this chapter. In addition to simple one-way or one-factor ANOVA described above, other types are available to analyse more complex situations involving several factors. Again, these are beyond the scope of this chapter. 

A one-way analysis of variance (ANOVA) (44, 45) was then performed on the data listed in Table V for each element. The ANOVA was followed with a Student-Newman-Keuls test (46) to determine the number of subgroupings that resulted from differences in the mean metal concentrations. Six elements (Cu, Fe, Mn, Ni, Pb, and Zn) were shown to be at significantly different concentrations when compared between the seven groupings. 

Figure 4.5 The effect of 6-(N.N-di- -propylamino)tetrahydrobenzo[6 thiophene (34) and 5-(N,N-di- -propylamino)tetrahydrobcnzo[6]thiophene (35) on the locomotor activity of reserpinised rats. Data are presented as mean S.E.M. (n = 4). P<0.05 (Student-Newman-Keuls test).

All results are expressed as mean SD or SEM. The group means were compared by analysis of variance (ANOVA) followed, when appropriate, by a comparison of means by Student-Newman-Keuls test. p<0.05 was considered significant. 

Means in each row with the same letter are not significantly different at 5% level (Student-Newman-Keuls Test). 

Different indices in the same line characterize significant differences (P < 0.05) found using the Student-Newman-Keuls test. 

Analyzing some specific strains. Parent I had the best performance of all parent strains its diploids also seem to be superior to all other diploids (not statistically tested). In the different crosses, however, the activity of their recombinants (Rec M//I, Rec Bin, Rec P//1) varied for example the cross between M and I yielded the best recombinants for biomass and COD (Student-Newman-Keuls test, a=0.05) with an intermediate performance in relation to that of the parents, while the cross between B and I produced recombinants for biomass and COD (Student-Newman-Keuls test, a=0.05) that were less efficient than the other recombinants and less...

Different letters indicate statistically significant differences found with a Student-Newman-Keuls test. Sample sizes are shown within bars. Groups male = male present in cage with female urine = female treated with male urine on the nasal philtrum saline = control females treated with saline. Adapted from Solomon et al. (1996).

Analysis of variance (ANOVA) was performed using the general linear model procedure to determine significant differences in the concentration of volatile compeunds of Rojal wines on different vintages. Student-Newman-Keuls test was conducted when the samples exhibited significance between them, with the level of significance set at P<0.05. Both ANOVA and Student-Newman-Keuls test were performed with SPSS 19.0 (2010) for Windows statistical package. 

Blend Ratios. Blends of 0, 1,3.3,10,33, or 100 pg of racemic lavandulol with 100 pg of racemic lavandulyl senecioate were tested from 2 to 23 May 2001, with traps and lures replaced on 16 May. In this and subsequent trials, data was transformed [(x + 0.5) ] and analyzed by one-way ANOVA, followed by a means separation test (Student-Newman-Keuls test, a = 0.05). 

Table 3 summarizes the mouse studies. There was a tremendous increase in the number of regenerated myelinated axons in the large pore conduits as compared to the small pore conduits, even though both were fabricated from the same collagen material (p < 0.05, Student-Newman-Keuls test). 

Results are expressed as average standard deviation. Significantly higher than small pore conduits, p is < 0.05 Student-Newman-Keuls Test. 

Duncan s assures a set alpha level or type I error rate for all tests when means are separated by no more than ordered step increases. Preserving this alpha level means that the test is less sensitive than some others, such as the Student-Newman-Keuls. The test is inherently conservative and not resistant or robust. 

Data obtained from animal experiments were expressed as mean standard error ( SEM). Statistical differences between the treatments and the control were evaluated by ANOVA and Students-Newman-Keuls post-hoc tests, p < 0.05 was considered to be significant ( p < 0.05 p < 0.01 p < 0.001). 

Data are expressed as the means SE. Statistical significance is assessed by two-tailed unpaired Student s t-test or one way analysis of variance (ANOVA) followed by either Dunnett s test for multiple comparisons vs. control or the Newman-Keuls test for all pair-wise comparisons. Tests indicating a value of P < 0.05 indicate a statistically significant difference between groups. 

All data were expressed as means SEM. The Student s t test was used when two groups of data were compared. For multiple comparisons the Newman-Keuls test was used. Other statistical tests, when used, are indicated in the appropriate figure legends. A value of P < 0.05 was considered statistically significant. 

Statistical Analysis. Data were statistically analyzed by a two-way analysis of variance, and where significant differences were found, a Student-Newman-Keuls (SNK) multiple range test or Duncan s multiple-range test at a probability of a =... 

Mean values for serum fatty acid composition (n = 5) within a row having different superscripts (m, n for fat effect x, y for CLA effect A, B, Q and D for interaction effect) are significantly different by two-way ANOVA and Student-Newman-Keuls (SNK) multiple range test (P< 0.05). The factorial design of dietary treatments allowed for an n = 10 in the statistical analysis of main effects. 

Statistical treatments. The data were processed with the SAS statistical package version 6.11, 4 edition (SAS Institute, Inc., Cary, NC). ANOVA analyses were performed at level a = 0.05, according to the model attribute = product + subject + product x subject, with subject as a random effect. Means were compared with the Newman - Keuls multiple comparison test (Student t...
