analysis

[ah-nal´ĭ-sis] (pl. anal´yses)
separation into component parts.
activity analysis the breaking down of an activity into its smallest components for the purpose of assessment.
bivariate analysis statistical procedures that involve the comparison of summary values from two groups on the same variable or of two variables within a group.
blood gas analysis see blood gas analysis.
chromosome analysis see chromosome.
concept analysis examination of the attributes of a concept as it occurs in ordinary usage in order to identify the meanings attached to the concept.
content analysis a systematic procedure for the quantification and objective examination of qualitative data, such as written or oral messages, by the classification and evaluation of terms, themes, or ideas; for example, the measurement of frequency, order, or intensity of occurrence of the words, phrases, or sentences in a communication in order to determine their meaning or effect.
correlational analysis a statistical procedure to determine the direction of a relationship (positive or negative correlation) between two variables and the strength of the relationship (ranging from perfect correlation through no correlation to perfect inverse correlation and expressed by the absolute value of the correlation coefficient).
analysis of covariance (ANCOVA) a variation of analysis of variance that adjusts for confounding by continuous variables.
data analysis the reduction and organization of a body of data to produce results that can be interpreted by the researcher; a variety of quantitative and qualitative methods may be used, depending upon the nature of the data to be analyzed and the design of the study.
ego analysis in psychoanalytic treatment, the analysis of the strengths and weaknesses of the ego, especially its defense mechanisms against unacceptable unconscious impulses.
gait analysis see gait analysis.
gastric analysis see gastric analysis.
multiple-locus variable number of tandem repeat analysis (MLVA) a laboratory tool designed to recognize tandem repeats and other qualities in the genome of an individual to provide a high resolution DNA fingerprint for the purpose of identification.
multivariate analysis statistical techniques used to examine more than two variables at the same time.
power analysis a statistical procedure that is used to determine the number of required subjects in a study in order to show a significant difference at a predetermined level of significance and size of effect; it is also used to determine the power of a test from the sample size, size of effect, and level of significance in order to determine the risk of Type II error when the null hypothesis is accepted.
qualitative analysis the determination of the nature of the constituents of a compound or a mixture of compounds.
quantitative analysis determination of the proportionate quantities of the constituents of a compound or mixture.
SNP analysis analysis of single nucleotide polymorphisms to assess artificially produced genetic modifications or identify different strains of an organism.
transactional analysis a type of psychotherapy based on an understanding of the interactions (transactions) between patient and therapist and between patient and others in the environment; see also transactional analysis.
analysis of variance ANOVA; a statistical test used to examine differences among two or more groups by comparing the variability between the groups with the variability within the groups.
variance analysis the identification of patient or family needs that are not anticipated and the actions related to these needs in a system of managed care. There are four kinds of origin for the variance: patient-family origin, system-institutional origin, community origin, and clinician origin.
vector analysis analysis of a moving force to determine both its magnitude and its direction, e.g., analysis of the scalar electrocardiogram to determine the magnitude and direction of the electromotive force for one complete cycle of the heart.

Dietary analysis. - A total [greater than]7700 food particles were digitized or counted for the 50 individuals sampled in this study.
Although the dietary analysis and the species analysis were conducted on different animals 2 yr apart, each shows a changing trend through the LTR continuum which may be linked.
In discussing these conflicting results, they discounted the balance of the scientific literature on the subject, which supports a beneficial cholesterol-lowering effect of oat bran, noting that few, if any, studies have included adequate low-fiber controls and dietary analysis of the possible "substitution effect." In an editorial regarding the oat bran controversy, Connor[11] recommended that a larger controlled and randomized study using hypercholesterolemic subjects in a crossover design similar to the Swain study be undertaken to answer these questions more conclusively.
Students are also encouraged to purchase the dietary analysis software to analyse their own and 'Bobbie's' diet.
In addition, the dietary analysis was completed before the availability of the improved database for fatty acids composition of Australian foods (27).
Key words: database, diet, dietary analysis, fatty acid, food composition, n-3 polyunsaturated fatty acid (PUFA)
For most foods, these low values often round down to zero when reported to a single decimal place and so it is likely that such fatty acids will be consistently underreported in any dietary analysis. Hence there is a need to measure and report fatty acid concentrations in foods as mg/l00 g edible food portion or g/100 g to two decimal places (e.g.
The first involved dietary analysis of food provided using the Guide's invoice method and included foods from core food groups.
In the past, researchers, dietitians, nutritionists and teachers were the primary users of dietary analysis programs.
Compared to other dietary analysis programs based on Australian foods, FoodScan 2000, in my opinion, ranks at the top end.
