Statistics review 9: one-way analysis of variance. [PDF]

open access: goldCrit Care, 2004
This review introduces one-way analysis of variance, which is a method of testing differences between more than two groups or treatments. Multiple comparison procedures and orthogonal contrasts are described as methods for identifying specific differences between pairs of treatments.

One-way analysis of variance with unequal variances. [PDF]

open access: greenProceedings of the National Academy of Sciences, 1989
We have designed a statistical test that eliminates the assumption of equal group variances from one-way analysis of variance. This test is preferable to the standard technique of trial-and-error transformation and can be shown to be an extension of the Behrens-Fisher T test to the case of three or more means.

Heteroscedasticity in One Way Multivariate Analysis of Variance [PDF]

open access: hybridJournal of Physical Mathematics, 2018
This work aimed at developing an alternative procedure to MANOVA test when there is problem of heteroscedasticity of dispersion matrices and compared the procedure with an existing multivariate test for vector of means. The alternative procedure was developed by adopting SatterthwaiteA¢Â€Â™s approach of univariate test for unequal variances.

Role of analysis of variance (One way-anova) in music [PDF]

open access: goldInternational Journal of Applied Research, 2020
Testing a New Technique but not sure how it stack up against all the alternative is very difficult as most of the options sound similar to each other so picking the best out of them is a challenge. Consider a scenario we have three music treatment to be apply on student to see their reaction as music enhance the concentration and consequently help ...

ONE-WAY ANALYSIS OF VARIANCE (ANOVA) IN STATA SOFTWARE

open access: bronzeEkologiya cheloveka (Human Ecology), 2014
In the article, we have presented theoretical principles of one-way analysis of variance (ANOVA) for comparisons of three or more independent groups. Examples of the use of ANOVA with manual calculations using formulas have been given as well as algorithms of the use of ANOVA in STATA software.
