Final answer:
Scientists should describe the limitations in their final report and may repeat the experiment to confirm the results.
Step-by-step explanation:
When scientists see that the data collection or analysis from their experiment has limitations, they should describe the limitations in detail in their final report. This is important because it allows other scientists to understand the potential weaknesses or flaws in the study. Additionally, scientists may repeat the experiment to see if it still has limitations and to confirm the results. Ignoring the limitations would be unscientific and could lead to inaccurate conclusions.
