How many utterances does MLU have?
Mean length of utterance (or MLU) is a measure of linguistic productivity in children. It is traditionally calculated by collecting
100 utterances
spoken by a child and dividing the number of morphemes by the number of utterances. A higher MLU is taken to indicate a higher level of language proficiency.
How do you count utterances in a language sample?
One you have a document with just the child’s utterances, go to Tools —> Word Count. Step Three:
Divide the number next to Words
(113 in this example) by 50 (the total number of utterances). This calculation gives you an MLU of 2.26.
What is the difference between utterance and sentence?

the sum divided by the count
.
