## Variable

An element in a model. For example, in the model RS&Pt+1 = a + b Tbill t + et, where RS&Pt+1 is the return on the S&P in month t+1 and Tbill is the Tbill return at month t, both RS&P and Tbill are "variables" because they change through time; i.e., they are not constant.

## Variable

Anything that does not have a set value. In basic algebra, a variable is often expressed as "x." Variables in economics and finance may be measures such as GDP, prices, or interest rates. Analysts use complicated equations to determine the value of some variables at the present time and even more complicated equations to predict their possible future values. See also: Regression.

## variable

Something, such as stock prices, earnings, dividend payments, interest rates, and gross domestic product, that has no fixed quantitative value. See also dependent variable, independent variable.

The loading productivity was significantly different among the above four class variables (Table 5).
To test for group-level differences in the emphasis placed on valence and expectancy, we performed an unbalanced ANOVA in which the standardized beta weights for valence and expectancy were the dependent variables and the student group was the independent class variable. We found no significant difference (p = .33) across groups in the importance of valence and no significant difference (p = .23) across groups in the importance of expectancy.
To verify the lack of any significant treatment effect for personal satisfaction, we ran an unbalanced ANOVA in which the standardized beta weight for personal satisfaction was the dependent variable and funding source the independent class variable. This analysis indicated no statistically significant differences (p=.749) across the three funding source categories regarding the influence of personal satisfaction.
There was also no significant linear trend (F(1,251) = 0.237, p = .627) nor quadratic trend (F(1,251) = 0.179, p = .170) of VMRT scores across the hand preference class variable. Figure 2 shows the VMRT means, standard errors and standard deviations for the hand preference classes.
This multidimensional thyroid disease dataset contains 29 attributes with 7 class variables. This dataset is collected from the website link [Andrew et.al.(2010)].

Major transformations are occurring in Turkey with regards to social class variables, such as income, education, occupation and neighborhood differentiation as well as consumption patterns and lifestyle.
This article takes the assumption that the latter two, student and class variables, are difficult if not out of the control of the teacher, suggesting that educators look more into their own role as facilitators in avoiding issues and if necessary in resolving them as professionally and as quickly as possible.
In seeking an empirical test of women's presence in the public sphere, Davidson grapples with a number of key issues, such as the ambiguities of a stark public-private distinction (recognizing that theaters, for example, harbor aspects associated with both); the significance of how women actually behaved in these public settings (was their public presence central and equal, or were they displayed in traditional roles as wives and mothers?); how class variables had an impact on the presence and on the type of presence shown by women (with differentiation being a more salient feature for middle and upper class women); and how regional variables within France may have played a role in women's public presence.
