Review Questions

  • How does statistical analysis contribute to data-driven decision-making in organizations?
    • Statistical analysis contributes to data-driven decision-making by providing a framework for understanding complex datasets. It allows organizations to identify patterns and trends that inform their strategies and actions. By quantifying relationships between variables, statistical analysis helps eliminate guesswork, enabling businesses to make informed decisions that are backed by empirical evidence.
  • Discuss the difference between descriptive statistics and inferential statistics in the context of statistical analysis.
    • Descriptive statistics focuses on summarizing and presenting the main features of a dataset through measures like mean and standard deviation.
