Final answer:
Experimental controls provide a comparison baseline but do not remove the need for large sample sizes, statistical tests, or sufficient measurements in scientific experiments.
Step-by-step explanation:
Experimental controls are essential components in scientific experiments. They allow comparison between groups that differ in only the independent variable, hence addressing the cause-and-effect relationships. However, experimental controls do not eliminate the need for large sample sizes, statistical tests, or measurements. Large sample sizes are still necessary to ensure that the results are statistically significant and can be generalized. Statistical tests are used to analyze the data and determine whether the differences observed between groups are likely due to the independent variable or just due to chance.
Moreover, sufficient measurements are critical for obtaining reliable and precise data. Therefore, while experimental controls provide a baseline for comparison, they do not remove the need for these other important aspects of experimentation.
