Correlation measures the strength and direction of a relationship between two variables, but it does not imply that one causes the other. A small standard deviation indicates that the values are clustered tightly, while a large one suggests a wide variation across the dataset.

It quantifies the likelihood of an event occurring, expressed as a number between 0 (impossible) and 1 (certain). The range provides the simplest view by subtracting the smallest value from the largest.
This is where sampling comes in, and it introduces the critical concept of bias. Simple random sampling gives every member an equal chance of selection, reducing selection bias and allowing researchers to generalize findings back to the larger group with a measurable degree of confidence.

It provides a structured framework for asking questions, testing hypotheses, and drawing reliable conclusions from evidence rather than intuition alone. Within quantitative data, we further classify numbers into discrete counts and continuous measurements, a distinction that dictates which statistical methods are appropriate.
