In order for estimates to be statistically efficient, the units within a sample should as different as possible. O b. In order for estimates to be statistically efficient, the units within a cluster should be as different as possible. O c. In order for estimates to be statistically efficient, the units within a cluster should be as same as possible. O d. In order for estimates to be statistically efficient, the units within a sample should be as same as possible. A survey frame: Select one: O a. Is a list of names of the population of a country or any region. O b. Provides a non-randomly selected list of a survey population. O C.
