hey Brittany, I am far from being a fieldtrip profi, but as far as I can
get you can either use

ft_freqgrandaverage and average over frequencies (cfg.parameter='freg'), or
you precise cfg.avgoverfreq      = 'yes' in the  ft_freqstatistics. Of
course you could also change the steps of ft_freqanalysis to bigger
steps... (for example cfg.foi          = 7:1:31 for analysis from 7 to 31
in steps of 1 hertz

cheers k
