It would really help to have more context, even hypothetical, but relevant, context. Are the behaviors independent, as in sequence doesn't affect outcome? If not, what would comparison with random pattern tell you? If the behaviors are associated with an outcome, is that outcome different for each behavior? Do combinations of behaviors result in different outcomes?

The target of the research is playing behavior of pre-schoolers. The different types of child play, e.g. construction play, are observed by coding individual behaviors which are - theoretically - indicative of this particular type of play. We want to test if what we see is random distribution of varieties of play behavior or if the sequence of behaviors can be interpreted as coherent and representative of a pre-defined type.

Have a look at this:

Article Sequence analysis as a method for psychological research

thank you, I will try and locate the publication

great material, exactly what I was looking for! Excellent!
