Dear List,
Having taken a look at Geremy's blog I dowloaded the above to check my
distant power calculations. Cant make head nor tail of it. Fruit and
veg pilot work indicated my Scots population ate a daily mean 3.6(SD
2.0) portions. We attempted to get a sample size that would demonstrate
a 1 portion per day increase in a RCT with 80% power and P<0.05 and came
up with 102 people. Don't seem to be getting that now can anyone
advise??
Many Thanks
Stephen
