Question

Which phrase indicates a limit to the scientific accuracy of the experiment?

For the study of a particular drug, Marcus proposes an experiment with a particular population. Approximately 200,000 people in the United States take this drug. He started out with a sample size of 300 people. First, he conducts research on the medical history of the people in his study. He collects the information using reliable sources. He decides to repeat the experiment using a larger sample size.

Answer 1

The initial sample size of 300 people indicates a limitation in the scientific accuracy of Marcus's experiment, necessitating repetition with a larger sample to enhance validity and reliability.

Step-by-step explanation:

The phrase that indicates a limit to the scientific accuracy of the experiment conducted by Marcus is the initial sample size of 300 people. While sampling in research is a common practice, the sample size and how well it represents the population are crucial factors that establish the validity and generalizability of the experiment's results. Marcus's decision to repeat the experiment with a larger sample size suggests recognition of the potential limitations in the precision and reliability of his findings due to the smaller initial sample size compared to the population size of 200,000 people taking the drug.

Answer 2

The phrase that indicates a limit to the scientific accuracy of the experiment is when Marcus decides to repeat the experiment using a larger sample size.

Step-by-step explanation:

The phrase that indicates a limit to the scientific accuracy of Marcus' experiment is when he decides to repeat the experiment using a larger sample size. This indicates that the initial sample size of 300 people might not be representative enough of the entire population of approximately 200,000 people in the United States taking the drug. By increasing the sample size, Marcus can gather more data and increase the reliability and generalizability of his results.
