Random sampling is helpful for several reasons, and your options highlight key benefits:
1. **Reasonably Accurate**: Random sampling can provide a sample that is representative of the larger population, which helps in making accurate inferences.
2. **An Economical Method of Data Collection**: It often requires less time and cost compared to other sampling methods, as it allows researchers to gather data from a smaller group while still reflecting the larger population.
3. **Free from Personal Biases**: Since individuals are selected randomly, the chances of introducing personal biases in selecting participants are minimized, leading to more objective results.
Therefore, the correct answer is **All of the above**. Random sampling incorporates all of these advantages, making it a valuable method in research and data collection.
