A researcher numbers 850 employees from 001 to 850. Using a random digit table, she reads three-digit numbers and selects the corresponding employees, ignoring repeats and numbers above 850, until she has 50 distinct employees.
This procedure produces a
- A
Cluster sample
- Bcheck_circle
Simple random sample
- C
Systematic sample
- D
Stratified sample
Explanation
Each employee has equal chance of selection and every group of 50 has equal probability. This is a standard SRS using a random digit table.
