A population contains 2,000 units, and a sample of 100 units is required. In systematic sampling, the sampling interval is:
Correct answer: B. 20
- A. 10
- B. 20
- C. 100
- D. 200
Explanation
The sampling interval is calculated as N divided by n, so 2,000 divided by 100 equals 20. After a random starting point, every twentieth unit is selected.
