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.
