Question

in this illustration, different sample sizes influence the results of the experiment. however, only male rats should have been studied, because they more accurately represent the population of humans who use cells phones. hypothesis: exposure to cell - phone radiation increases the incidence of cancer. control group: baseline placement into treatment groups (no independent variable change). independent variable: (what the researcher changes in an experiment.) cell - phone exposure. dependent variable: (what the researcher measures in an experiment.) incidence of cancer. results from data: male rats had higher incidence of cancer. cell - phone radiation increases the incidence of cancer in male rats, but not in female rats. conclusion: false; both sexes should always be presented whenever possible. true; sex rarely has an impact on the results of an experiment and a small sample size should always be the goal of the researcher. need help on this question?

Explanation:

In scientific experiments, to get more accurate and general - izable results, both sexes should be included whenever possible as sex can influence experimental outcomes. Also, a researcher should aim for an appropriate sample size rather than always a small one.

Answer:

False; both sexes should always be presented whenever possible.
