  2. Continuous or discrete variable - Wikipedia

    en.wikipedia.org/.../Continuous_or_discrete_variable

    In continuous-time dynamics, the variable time is treated as continuous, and the equation describing the evolution of some variable over time is a differential equation. [7] The instantaneous rate of change is a well-defined concept that takes the ratio of the change in the dependent variable to the independent variable at a specific instant.

  3. Continuum (measurement) - Wikipedia

    en.wikipedia.org/wiki/Continuum_(measurement)

    In social sciences in general, psychology and psychiatry included, data about differences between individuals, like any data, can be collected and measured using different levels of measurement. Those levels include dichotomous (a person either has a personality trait or not) and non-dichotomous approaches.

  4. Appraisal theory - Wikipedia

    en.wikipedia.org/wiki/Appraisal_theory

    Within the continuous versus categorical nature of appraisal and emotion, there are many standpoints of the flow of this appraisal process. To begin, Roseman's (1996) model shows that appraisal information "can vary continuously but categorical boundaries determine which emotion will occur".

  5. Log-linear analysis - Wikipedia

    en.wikipedia.org/wiki/Log-linear_analysis

    Violations to this assumption result in a large reduction in power. Suggested solutions to this violation are: delete a variable, combine levels of one variable (e.g., put males and females together), or collect more data. 3. The logarithm of the expected value of the response variable is a linear combination of the explanatory variables.

  6. Moderation (statistics) - Wikipedia

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

    If the first independent variable is a categorical variable (e.g. gender) and the second is a continuous variable (e.g. scores on the Satisfaction With Life Scale (SWLS)), then b 1 represents the difference in the dependent variable between males and females when life satisfaction is zero. However, a zero score on the Satisfaction With Life ...

  7. Categorical variable - Wikipedia

    en.wikipedia.org/wiki/Categorical_variable

    A categorical variable that can take on exactly two values is termed a binary variable or a dichotomous variable; an important special case is the Bernoulli variable. Categorical variables with more than two possible values are called polytomous variables; categorical variables are often assumed to be polytomous unless otherwise specified.

  8. Analysis of covariance - Wikipedia

    en.wikipedia.org/wiki/Analysis_of_covariance

    ANCOVA evaluates whether the means of a dependent variable (DV) are equal across levels of one or more categorical independent variables (IV) and across one or more continuous variables. For example, the categorical variable(s) might describe treatment and the continuous variable(s) might be covariates (CV)'s, typically nuisance variables; or ...

  9. Cognitive categorization - Wikipedia

    en.wikipedia.org/wiki/Cognitive_categorization

    Categorization is a type of cognition involving conceptual differentiation between characteristics of conscious experience, such as objects, events, or ideas.It involves the abstraction and differentiation of aspects of experience by sorting and distinguishing between groupings, through classification or typification [1] [2] on the basis of traits, features, similarities or other criteria that ...
