Hi,
We're looking at the frequencies, forms, and functions of adjectives found in child directed speech in different types of corpora e.g. shared book reading and toy play. We'd like to conduct a power analysis to find out the minimum of data points required. I've previously used GPower to calculate sample sizes required to detect a particular effect size for experimental data, but I'm unsure about how to do this for corpus data, given that we're more interested in data points required rather than number of participants.
Any help would be much appreciated!
Thanks,
Jamie
