  2. Dependent and independent variables - Wikipedia

    en.wikipedia.org/wiki/Dependent_and_independent...

    A variable is considered dependent if it depends on an independent variable. Dependent variables are studied under the supposition or demand that they depend, by some law or rule (e.g., by a mathematical function), on the values of other variables. Independent variables, in turn, are not seen as depending on any other variable in the scope of ...

    Example 22:53, 19 December 2024 (UTC) Things to include in your description: Identify the subject: Link to several major articles or lists within the scope of the proposed project. Show the subject is big enough: Link to categories within the scope of the proposed project.

  4. Design of experiments - Wikipedia

    en.wikipedia.org/wiki/Design_of_experiments

    The same is true for intervening variables (a variable in between the supposed cause (X) and the effect (Y)), and anteceding variables (a variable prior to the supposed cause (X) that is the true cause). When a third variable is involved and has not been controlled for, the relation is said to be a zero order relationship. In most practical ...

  5. Repeated measures design - Wikipedia

    en.wikipedia.org/wiki/Repeated_measures_design

    The independent variable is the time (Levels: Time 1, Time 2, Time 3, Time 4) that someone took the measure, and the dependent variable is the happiness measure score. Example participant happiness scores are provided for 3 participants for each time or level of the independent variable.

  6. Regression analysis - Wikipedia

    en.wikipedia.org/wiki/Regression_analysis

    The response variable may be non-continuous ("limited" to lie on some subset of the real line). For binary (zero or one) variables, if analysis proceeds with least-squares linear regression, the model is called the linear probability model. Nonlinear models for binary dependent variables include the probit and logit model.

  7. Mediation (statistics) - Wikipedia

    en.wikipedia.org/wiki/Mediation_(statistics)

    Simple mediation model. The independent variable causes the mediator variable; the mediator variable causes the dependent variable. In statistics, a mediation model seeks to identify and explain the mechanism or process that underlies an observed relationship between an independent variable and a dependent variable via the inclusion of a third hypothetical variable, known as a mediator ...

  8. Wikipedia:WikiProject Council/Proposals - Wikipedia

    en.wikipedia.org/wiki/Wikipedia:WikiProject...

    In 2024, we are changing the proposal process. We are trying to reduce the number of failed attempts to start groups. While we re-structure the pages, please do not propose any new groups. In the meantime, please consider two thousand existing projects and/or try to revive one of the many dormant WikiProjects. If your group can't wait for the ...

  9. Variable and attribute (research) - Wikipedia

    en.wikipedia.org/wiki/Variable_and_attribute...

    Attributes are closely related to variables. A variable is a logical set of attributes. [1] Variables can "vary" – for example, be high or low. [1] How high, or how low, is determined by the value of the attribute (and in fact, an attribute could be just the word "low" or "high"). [1] (For example see: Binary option)
