SummaryResults of ecological studies that involve the use of multivariate analysis of variance techniques for testing various hypotheses, interesting from the point of view of comparing the linear functions of parameters, were considered. For testing the most interesting hypotheses on a variety of interaction effects and on contrasts of class means, the application of a multivariate test statistic is recommended. Canonical variate analysis is used for graphical presentation of the results of multidimensional experiments. In this paper it is shown how a generalized form of canonical variate analysis can be useful to reveal which parametric functions of a multivariate analysis of variance model are responsible for rejecting the linear hypothesis. As an example, an analysis was made of an ecological study of trace element accumulation in plants of Italian ryegrass as a method of biomonitoring of air pollution.

Masseter Muscles

The purpose of this study was to compare the muscle activation of singers and instrumentalists while performing simple vocal exercises. Volunteer participants ( N = 28) were undergraduate music majors and minors, with an equal number being vocalists and instrumentalists. Participants performed five vowel sounds (ah, eh, ee, oh, oo), while electromyography of the zygomaticus and masseter muscles was sampled at 1,000 Hz. A statistically significant multivariate analysis of variance effect was obtained and follow-up analyses of variance showed instrumentalists had more masseter muscle activation than vocalists when performing “eh” and “ee.” Instrumentalists also had more zygomaticus muscle activation than vocalists when performing the “eh” vowel, but vocalists had more zygomaticus muscle activation when performing the “ah” vowel.

Variate Analysis

SUMMARYData for the quantity of ammo acids consumed and their flow rates at the proximal duodenum for 33 diets fed to sheep have been statistically analysed by both univariate and multivariate methods. Analysis of variance of net loss (g/day) between mouth and duodenum of individual and total acida was not conclusive. Canonical variate analysis which takes regard of the correlations between different acids both within and between diets provided a conoise method of discriminating between diets. The advantage of this method in generating a unified account of digestion within the rumen is that it effectively reduces the problem from one of many dimensions to a situation where only the first few transformed variables need to be considered.

This study examines the expression of selflessness – the tendency to ignore one’s own needs and serve others’ needs – in Rorschach protocols of women suffering from anorexia nervosa. The protocols of 35 women suffering from anorexia nervosa were compared to 30 protocols of a psychiatric comparison group. A multivariate analysis of variance over five variables (AG, PER, PHR, COP, and GHR) was significant: Anorexic patients showed higher characteristics of selflessness compared to the psychiatric comparison group. These findings contribute to the validation of the Rorschach technique and to the clinical observation of selflessness in anorexic patients, and they emphasize specific characteristics in the treatment of anorexia nervosa patients.

Anxiety Levels

Interactions of attention and verbalization were investigated for effects of self-reported arousal and state-anxiety. Levels of verbalization from silence through talking-without-a-listener to disclosure were compared while self-directed attention was manipulated for sensation versus general thoughts and feelings. Following a stimulus, disclosure of sensations was expected to reduce state anxiety and increase energetic arousal significantly more than disclosure of thoughts. Based on a randomly assigned sample of 120 men, a 3 × 2 × 2 multivariate analysis of variance indicated a significant interaction in the predicted directions. A significant interaction was also found for the 3 × 2 interaction for energetic arousal. For state anxiety means were in the predicted direction. Results indicate that verbalization of sensations is more energizing and calming than silence, while for general thought, silence is more energizing and calming than verbalization. The results suggest efficacy in reframing self-talk to quiet awareness and in communicating sensed distinctions as they emerge.

Curve Reduction

This paper identifies the leading causes for large variations in the calculated fatigue lives of the hypothetical pitch link experiment of the American Helicopter Society, conducted in cooperation with all U.S. manufacturers of military helicopters. Multivariate Analysis of Variance (MANOVA) is used to show that approximately 85 percent of the variations can be attributed to only two of the five analytical steps involved and the interactions between them. These steps are the method of cycle counting and the amount of S/N curve reduction.
