Answer
Uncertainty in results diminishes the reliability of conclusions drawn. It is essential to quantify and discuss this uncertainty to understand the confidence level in findings.

Answer
Random errors can result from unpredictable variables in the experiment. Although they are usually less impactful than systematic errors, their presence can still challenge the validity of results.
