What is the purpose of numbering the units on the frame from 1 to N?
What is the purpose of numbering the units on the frame from 1 to N?
- To select the random start
- To determine the total population size
- To ensure each unit has an equal chance of being selected
- To establish the sampling interval (correct)
How is the sampling interval (K) calculated in systematic sampling?
How is the sampling interval (K) calculated in systematic sampling?
- By dividing the total population size by the desired sample size (correct)
- By subtracting the random start from the total population size
- By dividing the desired sample size by the total population size
- By multiplying the random start by the total population size
What is the purpose of selecting a random number between 1 and K?
