I wanted to draw that graph for a long time, as here in France we also have heated debates about the interpretation of international comparisons (mostly PISA).<br /><br />Three remarks about your graph:<br />- first, it would be useful to draw orthographic complexity against mean reading performance, since after all the real prediction is that orthographic complexity influences reading acquisition on average. I would therefore expect a stronger correlation than on your graph.<br />- Then, there is the complex issue of the relationship between mean and range. Many factors probably intervene. It might be that increasing the mean mechanically entails increasing the range. But maybe some countries manage to escape that law, and then it would be interesting to investigate why. At any rate, it would be informative to draw that graph for a start.<br />- the orthographic complexity scale that you used is obviously arbitrary. In fact it seems to be a simple ranking of languages (with some missing). Using a real estimate of orthographic complexity would push French and English higher up, and might change the relationship to some extent (perhaps more linear?). You can find such estimates in papers by Seymour, Borgwaldt, Landerl...Franck Ramushttps://www.blogger.com/profile/02656240693713885894noreply@blogger.comtag:blogger.com,1999:blog-5841910768079015534.post-26340493589105305142014-09-16T12:06:44.515+01:002014-09-16T12:06:44.515+01:0020% of children still failing.
