Evaluation of model performance using Pearson correlation analysis on datasets designed to test sensitivity to language variation.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Pearson correlation analysis |
| Dataset (including any stated split) | Tasks sensitive to language variation |
| Metric | Pearson Correlation |
| Unit | SCALAR |
| Direction | Higher is better |
| Results loaded | 3 of 3 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Pearson Correlation](<https://www.sota2.com/research/sota/pearson-correlation-analysis-on-tasks-sensitive-to-language-variation.md?metric=Pearson%20Correlation>): Higher is better; unit: SCALAR.
