Average sentence length in novels dataset (Avg-Sent-Len)

This dataset includes values on average sentence length per novel, as well as very basic metadata (author name and year of firstpublication), for several sets of 100 novels in multiple languages (English, French, German and Hungarian, for the period 1840-1920) derived from the European Literary Text Collection (ELTeC) as well as for one larger set of 1150 English-language novels from Project Gutenberg (for the period 1800-1960). 
This dataset is suitable for learning data visualization (scatterplots and regression plots) as well as data analytics (linear / polynomial regression).
