Math Correlations Data

Seven study-level correlation matrices for achievement and mathematics teaching-efficacy variables. The object is stored as a list containing the correlation matrices and their corresponding sample sizes, and is useful for examples involving correlation-matrix synthesis and path modeling.

Usage

math_correlations

Format

A nested list with two elements:

math_correlations

A named list of seven 3-by-3 correlation matrices. Matrix variables are ACH (achievement), PTE (personal teaching efficacy), and GTE (general teaching efficacy).

sample_size

Numeric vector of study sample sizes aligned with math_correlations.

Source
