In terms of the frequency of letters, how is it possible to have different frequent letters when the length of the text I'm analyzing is shorter?
At the moment, I'm comparing the frequencies of a long text and a subtext from that text. To my surprise, the most frequent letters changed. In the long one it was the letter
e followed by the letter
t, however in the small text it was
t followed by
e. Also, when I checked the frequency of different types of texts (e.g news articles), the frequency of letters also changed as well as the most frequent one.
The bottom line is, how can that be possible? It makes no sense to me.
