extraneous variable a factor that is not itself under study but affects the measurement of the study variables or the examination of their relationships.
independent variable in a mathematical equation or relationship between two or more variables, any variable whose value determines that of others; it represents the treatment or experimental variable that is manipulated by the researcher to create an effect on the dependent variable.

## variable

(1) Any attribute, phenomenon or event that can have different qualitative or quantitative values. Typically, a form of metadata goes with the variable, there is a variable definition that describes what is varying and there is a value for the variable. Variables are typically assessed in a clinical trial.
(2) In Study Data Tabulation Model (SDTM), variables describe observations with roles that determine the type of information conveyed by the variable about each observation and how it can be used.

In SDTM, variables include specific subtypes used in clinical research: "study variable" in trial design refers to a variable to be captured on the case record form (CRF); an "assessment" is a study variable pertaining to the status of a subject/patient, is usually measured at a certain time and is usually not compounded significantly by combining several simultaneous measurements to form a derived assessment (e.g., BMI, or a result of statistical analysis); an "endpoint" is a variable that pertains to the trial objectives.

All class variables including average small-end diameter of logs grappled per turn, average length of logs, the number of logs grappled per turn, and product type did not significantly affect most of the loading elemental times.
To determine whether the influence of classmate esteem is significantly higher for government funded students, we ran an unbalanced ANOVA in which the standardized beta weight for classmate esteem was the dependent variable and funding source the independent class variable. This analysis indicated marginally significant differences (p=.072) across the three funding source categories.

Although the results are constrained by limitations discussed in a subsequent section, overall, responses revealed that counselor educators demonstrated low to moderate levels of cultural bias based on race, gender, sexual orientation, and social class variables. Results indicated that counselor educators' bias varied across cultural domains.

The central purpose of this paper, which deals with the impacts of riding characteristics on voting behaviour, is to show: firstly, that more diverse tidings (in terms of bilingual, immigrant, or visible minority composition) are more likely to vote for the Liberals; secondly, that more affluent ridings support the Conservatives and reject the NDP; thirdly, that the two class variables (income and education) have opposing effects on NDP (and Conservative) support; and, lastly, that the Bloc Quebecois is rejected in the more ethnically diverse and more affluent ridings of Quebec.
All harvests data including lint yield, micronaire, UHM, UI, and strength were analyzed by Proc GLM, with year, replicate, gap type, and target OBPD as class variables. Where interactions involving year were significant, Proc GLM was run by year with replicate and gap type as class variables and OBPD as a continuous variable, fitting linear and quadratic main effects for OBPD as well as interactions with gap type.
Having said this, there is a high degree of consistency between the paternal class variables at the two time points, with 57.7% of the fathers remaining in the same class, and a correlation between the two variables of .55 (df = 4,201, p<.001).
Social class variables often influence the extent to which African Americans express certain culturally derived behaviors such as code switching, a practice in which individuals alter their behavioral patterns to conform to the current environment (Celious & Oyserman, 2001).
