Statistics - practice problems

Statistics is the mathematical science of analyzing and interpreting data. While its inputs may be uncertain or variable, its methods provide precise tools for uncovering patterns within seemingly random information. As classicists say, "Statistics is the exact sum of imprecise numbers."

At its core, statistics transforms raw data—no matter how chaotic it appears—into meaningful insights. By examining large datasets, statisticians can identify trends, test hypotheses, and make reliable predictions. Whether in science, economics, or everyday decision-making, statistics turns uncertainty into measurable knowledge.
