Thank you sir, cant wait for the next part!
It is no problem at all. There is always a new part every day.
What formula did u use to get standard deviation in 12a?
probably the first one in the formula sheet
on classwinz, go menu -> 6 statistic -> 1. 1-variable -> add your data -> AC -> OPTN (is under shift) -> 1 variable calc. For aqa it is σx and should be good, but I think a board asks for the Sx version which is the sample version
