Question

During a conference presentation, a scientist described the materials that she used and how she performed her experiments.

Which best explains why a scientist would share these details in a conference?
It tells the audience if the results support or contradict the hypothesis.
It tells the peers if the study is supported by mathematical models.
It informs the peers if the results are supported by other scientists.
It informs the audience if the study included controlled tests.

Answer 1

It informs the audience if the study included controlled tests.

Sharing materials and methods lets other scientists see the experimental design (including controls and variables) so they can judge the validity and reproducibility of the results.
