You want to find out which word categories (noun, verb etc.) are produced most frequently by the child (and which categories are produced at very low rates). Below you find a list of the categories produced by the child. For each of these categories indicate the frequency of occurrence and calculate percentages (based on the total number of words in the sample).

Treat compound nouns (back-pack, peanut butter, cinnamon roll) as one word, count names as nouns and do not count exclamations (e.g. oh) as a word.
