Question

directions: practice what you learned about repetition and replication by applying knowledge to multiple - choice questions. question 10 replication reduces variability in experimental results. what other ways does replication of a scientific investigation help our world? a. it ensures that the investigation is sound and valid b. it makes sure that scientists become more famous for their work c. it gives more people access to the research d. it provides the opportunity for increased government funding restate what the question is asking (max 5 words) most common incorrect answer c. it gives more people access to the research explain why it is incorrect. correct answer explain why this is the best answer. question 11 you have just tested your hypothesis 20 times and when analyzing your data you noticed that the results are not what you hoped for. what might you do differently after analyzing your results? a. send your research out to get it added to textbooks b. start research over from the observation stage c. use the data they collected to make a new hypothesis. d. reach out to colleagues and ask if they would test your hypothesis and compare results restate what the question is asking (max 5 words) most common incorrect answer c. use the data they collected to make a new hypothesis. explain why it is incorrect. correct answer explain why this is the best answer. question 12 in 2021, american scientists are attempting to replicate a study done in antarctica in the year 1945. what would the current scientists need to do to ensure their results are similar to the original study? a. change the variables in the new experiment and repeat it until they get the data they were expecting. b. assume they did everything correctly and publish the results to a scientific journal. c. research similar experiments to try to find errors in the initial study. d. replicate the initial experiment using the same variables to make sure the results are accurate

Explanation:

Question 10:

Replication in scientific investigations helps ensure the investigation is sound and valid by verifying results through repetition. It doesn't primarily aim to make scientists famous, give more people access to research, or secure government funding.

Question 11:

When results don't match expectations after multiple tests, using the collected data to form a new hypothesis is a scientific approach. Sending research to be added to textbooks prematurely, starting over from the observation stage without analyzing the data further, or just asking colleagues to test the same hypothesis without modifying it are not ideal next - steps.

Question 12:

To replicate a study accurately, current scientists should replicate the initial experiment using the same variables to ensure the results are accurate. Changing variables until getting expected data is unethical, assuming everything was correct without verification is hasty, and researching similar experiments to find errors in the initial study is not the main way to replicate the original study's results.

Answer:

Question 10: A. It ensures that the investigation is sound and valid

Question 11: C. Use the data they collected to make a new hypothesis

Question 12: D. Replicate the initial experiment using the same variables to make sure the results are accurate
