    I have been wading through a stats text and have some quick basic yes-no for you guys:

    If you randomly sample a normal distribution, are you sure to have independence and identical distribution?
    Is Identical Distribution and Equal Variance the same thing?
    Are tests that use comparison of means largely robust to viloations of normality and identical distribution?
    I keep running into ¨ensure a representative sample¨ and ¨beware of recognizable subsets (different operators, batches, etc)¨…arent these two ideas conflicting?
    Does randomization equal independence?
    THANKS!!!!!!!!!!!!
