Statisitics question dont understand
Original post by ElectronDonor
i) What happens to the mean and variance/standard deviation when coding?
ii) How can you find the combined mean?
Spoiler
what is the m-5 part is that x bar or is that one independent value
Also what does the mean and standard deviation have to do with coding.

Nothing per se. However, before the days of computing, coding values made it easier to compute means and sds. If you look in the section in your textbook on coding it should give you the basic rules that show how mean and s.d. are affected by coding the data.
