What you mentioned is to compare the means of the groups. But in your case you can use the log likelihood test to find out whether the differences in the frequencies of the inflectional form and the periphrasic form in the two corpora are statistically significant, on the basis of four frequencies:

Frequency of the inflectional form in ICE-GB: a
Frequency of the inflectional form in ICE-SIN: b
Frequency of the periphrastic form in ICE-GB: c
Frequency of the periphrastic form in ICE-SIN: d

Hi, Dr. Xiao, I think, perhaps, the last category mentioned above is "ICE-SIN".

Frequency of the inflectional form in ICE-GB: a
Frequency of the inflectional form in ICE-SIN: b
Frequency of the periphrastic form in ICE-GB: c
Frequency of the periphrastic form in ICE-SIN: d

Yes thanks. I've corrected it.
