Question

question 3 when scientists report uncertainty in their data, they are ○ expressing concern over whether their data are correct. ○ stating that they do not know what their research means. ○ quantifying the degree of error and variability present in the data. ○ suggesting that others should not trust their conclusions.

Explanation:

• The first option is incorrect because reporting uncertainty is not about doubting data correctness, but about acknowledging inherent variability/error.
• The second option is wrong as uncertainty in data doesn't relate to not understanding research meaning.
• The third option is correct: Uncertainty in scientific data reporting is about quantifying how much error or variability exists (e.g., through confidence intervals, standard deviation), which helps in understanding the reliability of results.
• The fourth option is incorrect; reporting uncertainty is a transparent practice to show data reliability, not to dissuade trust.

Answer:

C. quantifying the degree of error and variability present in the data.
