Question

1. at which stage of the scientific process should a scientist look at experimental data from other scientists to set up a new experimental study?

a. observing

b. testing a hypothesis

c. forming a hypothesis

d. evaluating results

Explanation:

To determine the correct stage, we analyze each option:

• Option a (observing): This stage involves noticing phenomena, not reviewing others' data for a new experiment setup.
• Option b (testing a hypothesis): This is about conducting one's own experiment to test a hypothesis, not using others' data to set up a new study.
• Option c (forming a hypothesis): Before forming a hypothesis for a new experimental study, scientists often review existing experimental data (from other scientists) to identify gaps, trends, or areas to explore, which helps in formulating a relevant hypothesis and setting up the new study.
• Option d (evaluating results): This is about analyzing one's own experiment's outcomes, not using others' data to set up a new experiment.

Answer:

c. forming a hypothesis
