When developing an experiment design, which could a scientist take to improve the quality of the results?

The options missing are;

A. Make only a few changes to the manipulated variable.

B. Identify any biases about the answer to the scientific question.

C. Include as many details as possible when writing the conclusion.

D. Share her ideas through peer review.

B. Identify any biases about the answer to the scientific question.

Explanation:

Since the question is asking what can be done to improve the quality of the results, it means what can the scientist do to make sure that the result answers the question properly and has little or no biases.

Thus, looking at the options, the only one that comes close to actually improving on the quality of the results before finalizing is option B where the scientist is to identify any biases.
