I hold a degree in Statistics from East Tennessee State University. With a passion for numbers and analysis, I thrive on simplifying complex concepts for my students. My approach blends theoretical knowledge with real-world applications, ensuring a comprehensive understanding. From probability to data analysis, I guide students to excel in statistics with confidence. Let's unravel the mysteries of numbers together.
