This article presents information on the measures of testing for group differences between means. A summary of the more common measures of testing for group differences would include a simple t test for a pair of independent or dependent means and an F test for evaluating the difference between more than two means. The F test (named after R. A. Fisher) is also called the analysis of variance (ANOVA). The t value is computed through comparing the variance that is attributable to between-group variance to that attributable to within-group variance. The t value for dependent means is computed through comparing the variance that is attributable to between-subject variance to that attributable to within-subject variance. Computing for the F value for an overall test of the difference between more than two means is done through comparing the variance that is attributable to between-group variance to that attributable to within-group variance. When the obtained value exceeds the critical or tabled value, one can conclude that the probability of the obtained value occurring by chance alone is very small. Alternatively, the t and F values are interpreted using the results of a statistical package such as SPSS and the exact associated probability assigned to the obtained value.

Introduction In the history of Western music theory, technical works written in Greek on the general subjects of “music” (μoνσική) and “harmonics” (αρμoνικά) play an anomalous role. On the one hand, they are not “Western,” especially in the linguistic and geographic senses reinforced in the Middle Ages by the gradual schism between Eastern and Western Christendom. On the other hand, the tradition never ceased to exert an influence during this period, not only because some parts of it were carried over into the West by authors writing in Latin, but also because the early church readily acknowledged and accepted – though not without reservations – the ancient power of music and its centrality to human existence. This combination of causes was sufficient to sustain an interest in early writings on music, especially those in Greek, throughout the Middle Ages. Thus, unlike other early Eastern traditions, the tradition represented by Greek works on music and harmonics assumed a prominence in the West even as it acquired a sense of the esoteric and foreign, a duality of character it retains in the modern conception of “ancient Greek music theory.” Prior to the Middle Ages, the tradition of writing technical works in Greek “on music” (περì μoνσικηs), on the subject of “harmonics” (άρμoνικά), or as a general introduction (εìσαγωγη) to one or both subjects was extraordinarily resilient, extending easily over eight centuries. But by the collapse of Rome in the fifth century CE, the tradition had become moribund, though certainly not entirely forgotten. [ABSTRACT FROM AUTHOR]

A definition of the term "mean" is presented which refers to the arithmetic average of a series of numbers, computed by adding up the numbers in the series and dividing the total by how many numbers there are in the series.

A definition of the term "average household income," which means the estimated average income per household, is presented.

A definition of the term "average," which is accounting means a measure of central tendency used to indicate the size of the data taken as a whole as compared with that of particular items, is presented.

The entry presents a definition of the term x-bar chart. It is described as a quality control chart that shows the variations in the averages of samples.

A definition of the term "PASTA" is presented. It refers to Poisson Arrivals See Time Averages (PASTA). If arrivals to a queue are Poisson, the fraction of arrivals who find the process in some state is equal to the overall function of time the process is in that state.

A definition of the term "coefficient of variation" is presented. It refers to the ratio of the standard deviation to the mean of a random variable.
