Statistics teacher | Experienced educator in USA

With a Statistics major from George Fox University, my passion lies in deciphering the patterns hidden within data. As a seasoned tutor, I thrive on unraveling complexities and transforming them into understandable insights. From probability theory to regression analysis, I offer tailored guidance across various statistical realms. My mission is to empower students with the analytical tools they need to excel. Let's navigate the world of numbers together, making every concept crystal clear along the way.
