simple maths [ statistics ]The simple maths formula is used to calculate the keyness score in Sketch Engine. This score is used to identify terms, keywords and also key n-grams and key collocations.

It uses relative (per million) frequencies and, therefore, makes it possible to contrast corpora of unequal sizes. see Simple maths.
