which best describes the purpose of a control sample?\no to have more quantitative data to analyze at the end of the experiment\no to have more qualitative data to analyze at the end of the experiment\no to compare its results to those of a well - known scientist\no to compare its results to those with the experimental sample

Answer

Brief Explanations:

A control sample in an experiment is used as a baseline. Its results are compared to the experimental sample to determine the effect of the variable being tested. It is not about getting more data (quantitative or qualitative) just for the sake of having more data, nor is it for comparing to a well - known scientist's results.

Answer:

to compare its results to those with the experimental sample
