Summary Statistics and Correlation Matrix for Key Variables (N=1219)

Changning Ren's dataset provides the means, standard deviations, and a correlation matrix for a set of key variables, based on a sample size of 1219. It was last updated on June 1, 2026, and is available as a 5.5 KB XLS file under a CC-BY-4.0 license on figshare.

Use Cases

• Perform preliminary data exploration based on provided means and standard deviations.
• Conduct correlation analysis between variables based on the included correlation matrix.
• Use as a teaching example for descriptive statistics based on the summary metrics.
• Validate statistical assumptions based on the provided variable relationships.

Strengths

• Sample size of 1219 is explicitly stated.
• Key summary statistics (means, standard deviations, correlations) are pre-calculated.
• License is clearly defined as CC-BY-4.0, permitting reuse with attribution.

Limitations
