Inferential Statistics: The Pearson r Coefficient

These flashcards cover key concepts related to the Pearson r correlation coefficient and statistical control methods.

Pearson r

A statistic that measures the degree of association between two variables, often used to determine the strength and direction of their relationship.

Degree of Association (DoA)

A measure that examines the relationship between two variables, which can indicate how one variable may be affected by another.

Independent Variable (IV)

A variable that is manipulated or categorized to observe its effect on another variable.

Dependent Variable (DV)

A variable that is measured or observed in response to changes in the independent variable.

Zero-Order Correlation

A correlation between two variables without controlling for any other variables.

Statistical Control

The process of holding other variables constant to isolate the relationship between the independent and dependent variables.

Correlation Coefficient

A numerical value that represents the strength and direction of the relationship between two variables.

Partial Correlation Coefficient

A statistic that measures the relationship between two variables while controlling for the effect of one or more other variables.

Bivariate Relationship

A relationship involving two variables, typically one independent and one dependent.

Scatterplot

A graphical representation of the relationship between two quantitative variables, displaying data points in a two-dimensional space.
