Define simple random sampling. Choose the correct answer below. A. Simple random sampling is the process of selecting individuals from a population using a convenient sample. The sample is then called a simple random sample. B. Simple random sampling is the process of using chance to select individuals from a population to be included in the sample. The sample is then called a simple random sample. C. Simple random sampling is the process of obtaining a sample of size \( n \) from a population of the same size \( n \). The sample is then called a simple random sample. D. A sample of size \( n \) from a population of size \( N \) is obtained through simple random sampling if every possible sample of size \( n \) has an equally likely chance of occurring. The sample is then called a simple random sample.

The Deep Dive
When it comes to simple random sampling, the magic lies in its fairness! Imagine everyone in a population has an equal ticket in a lottery; that’s how individuals are chosen for the sample. This method ensures that each member has an equal chance of being selected, which helps in creating a representative sample free from bias. In practice, this approach is widely used in studies ranging from market research to clinical trials. By employing techniques such as random number generators or drawing names from a hat, researchers eliminate any chance of favoritism, leading to results that can be generalized to the entire population. Who knew science could be so fair and exhilarating?
