Tests
The following tests have been implemented and hopefully more will be implemented in the future
- Flesch Reading Ease
- Automated Readability Index (ARI)
- Flesch-Kincaid
- Coleman-Liau
- Gunning Fog
- SMOG
- Laesbarhedsindex (LIX)
How it works
The algorithms use a combination of sentences count and word length in grading the articles. It assumes that articles are written in a coherent manner. National Adult Literacy Study states the average U.S. adult reads at the 7th grade level. [1]
Known limitations
- The syllable counter included is inaccurate and will tend to over inflate scores on tests
- The graph for Fry test is non-linear along the y-axis and the fifth degree polynomial used to fit is only accurate to +/-1 block on the extremes
