Statistical analysis is a fundamental tool for understanding and solving real-world problems. Through various techniques such as experimental design, graphical representation of data, probability calculations, and inferential statistics, we can make informed decisions, predict outcomes, and assess risks in diverse fields. By applying statistical methods, we can validate
claims, analyse trends, and estimate parameters that describe complex systems, from scientific studies to business and sports analytics.
A nutrition research company conducted a study with 25 volunteers to test the effects of a new supplement called “NutriCore” over 3 months. The company reported an improvement in energy levels based on participants’ self-assessment.
Why can’t we conclude from this study that “NutriCore” increases energy levels for the entire population?
Provide at least two strong statistical reasons related to sample size, bias, or study design.
