????
say
of cousmrse bt the best nethod is a+hu_
ok
bt it is also depnend in the marking if it get 3 marks so use deviation method
use direct method only when the class interval has small numbers use assumed mean for the middle one and step deviation for large numbers for easy calculation. U can use any but if it is written to use a particular method u will have to do that.
The usage of methods doesn't depends on marking scheme
yes it depends
tq u both
tq u so much
