Verified step by step guidance1
Understand that 'empirical evidence' refers to information gathered through direct observation or systematic data collection, such as experiments or surveys.
Recognize that empirical evidence is based on actual data rather than theoretical reasoning or personal beliefs.
Note that empirical evidence can be subject to sampling variability and is not always exact, as it depends on the data collected.
Distinguish empirical evidence from conclusions drawn purely from logic or mathematical proofs, which do not rely on observed data.
Summarize that empirical evidence is the foundation for making informed conclusions in statistics because it relies on real-world data.
