The results of sentence length on ease and interest

There is an interesting relationship between the average sentence length, interest level of sentence, and ease of understanding. As the length of the sentences becomes longer, on one hand, it reduces the ease of the sentences, so it makes the sentences difficult to understand. On the other hand, it increases the level of sentence interest. The scale of the average sentence length has a direct positive linear correlation with the scale of interest level and a negative correlation with the scale of ease. For example, at an avereage sentence length of three words, the interest level is only one whereas the ease is ten. In contrast, at a high average sentence length of 20 words, interest has increased to seven while ease has dropped to four.
