a) Quantitative Analysis: In language acquisition research, the average length of child utterances at a given point in development is seen as an indicator of the child's development in terms of morphological and syntactic complexity. The average length of utterances (or mean length of utterances (MLU) is calculated on the basis of either words or morphemes. The procedure is as follows: (1) the number of words or morphemes is calculated for each utterance in the data sample; (2) the total number of words or morphemes is calculated; (3) the sum of the total number of words / morphemes is divided by the number of utterances.

Calculate the MLU value in words for the sample.

Treat compound nouns (back-pack, peanut butter, cinnamon roll) as one word. Do not count exclamations (e.g. oh) as a word. Give the MLU value with one decimal, e.g. 2.5 or 3.3.

b) Qualitative analysis: Analyse the word combination patterns in the child's two-word utterances, three-word utterances and four-word utterances and list the utterances corresponding to that type.

Word combination pattern in utterance 16: pronoun - verb
Further utterances corresponding to that pattern: 35

There are 14 additional patterns in the sample. Enter your answers in the blanks below in the same form as in the example.

Choose from the following list of categories:

noun, verb, adverb, preposition, pronoun, determiner.

If there are no other examples of a pattern enter / in the blank.

If there is more than one additional example of a pattern list them by using commas (e.g. 16, 35, 46).
