From the analysis of variance
, it was determined that there is a significant difference in the average modulus of elasticity in film 9 (LLDPE + UV absorber 0.60% w).
Analysis of variance
showed that the effect of experimental factors within probability level 1% on ratio root to shoot is significant (Table 1).
Analysis of variance
showed that different doses of nitrogen level alone and in combination with constant doses of phosphorus and potassium had no significant effect on plant height.
Fluorescence variables were analyzed using one-way analysis of variance
with means separated with Duncan's Multiple Range Test.
In order to determine the relationship between the experimental variable (site index parameters) and strength properties, all the data measured were subjected to an analysis of variance
and Duncan's mean separation test.
Least squares means, correlations, and analysis of variance
were calculated from these data using a Statistical Analysis Systems package designed and implemented by Barr and Goodnight, Department of Statistics, North Carolina State University.
Results of two-way ANOVA (Analysis of Variance
) also show significant interaction effect of gender and employment status.
To move beyond traditional research methods and into effect analysis, use statistical tools such as analysis of variance
, correlation analysis, multiple regression and structural equation modeling (these are described below).
The Analysis of Variance
revealed no significant difference in the performance times for the three trials.
The combination of a multi-factor analysis of variance
(ANOVA) with various subsidiary, ad hoc approaches suggested by the ANOVA or directly by the data, can establish an instructive hierarchy of salient physical and subjective parameters and illuminate some of their specific details.
Statistical techniques, including analysis of variance
, data distribution fitting, and bootstrap analysis, will be used for the evaluation of the analytical results.
A Friedman two-way analysis of variance
and a post-hoc test yielded a statistically significant difference between the lowest and highest mean ranks, [chi square] (22, N=36)=53.37, p [is less than] .001.
The analysis of variance
offers an excellent procedure for making tests about three or more means that is reliable.
The statistical analyses are based on the analysis of variance
. There is no shortage of ANOVA tables here!
The standard univariate and bivariate descriptive statistics are covered, including cross-tabulation, t-test, analysis of variance
, linear regression, and nonparametric techniques.
