👉 Deviation math is a branch of mathematics that focuses on the study of deviations from expected values or distributions, often used in probability theory and statistics. It quantifies how much a random variable or a set of data deviates from its mean or expected value, providing insights into the variability and uncertainty in data. Key concepts include measures like standard deviation (which captures the average distance of data points from the mean), variance (the square of standard deviation, representing spread), and percentiles (which describe how data points fall below a certain threshold). These tools help in understanding the spread, risk, and reliability of statistical models, making deviation math crucial for fields like finance, engineering, and data science where predicting and managing variability is essential.
