Statistics teacher | Tutor for 5 years
I earned my Statistics degree from Seminole State College of Florida. Equipped with a deep understanding of data analysis and interpretation, I'm here to guide you through the world of numbers. From probability theory to hypothesis testing, I'm committed to helping students grasp complex statistical concepts with clarity and confidence. Let's work together to unlock the mysteries of data and excel in your academic journey.
