Statistics teacher | Tutor for 7 years

With a degree in Statistics from Delaware State University, my passion lies in unraveling the complexities of data. Equipped with a deep understanding of statistical methodologies, I strive to empower students to conquer any numerical challenge they encounter. From probability theory to regression analysis, I am committed to fostering a clear understanding of statistical concepts. Let's navigate the world of numbers together, turning confusion into clarity one question at a time.

Questions

  • How do you find the median of an even number of numbers?
  • Assume that 10% of published books break even, 20% lose $10,000, 30% lose $20,000, and 40% net $10,000. What is the expected value of a random book?
