degrees of freedom
Degrees of freedom refer to the number of independent ways a system can move or be arranged. In statistics, it indicates how many values in a calculation can vary without breaking any constraints. For example, if you have a group of five people and want to know their average age, knowing the ages of four lets you determine the fifth, which means there are four degrees of freedom. In general, the concept can apply to various fields, such as physics, where it describes the different ways an object can move in space, based on its constraints.

Degrees of Freedom refer to the number of independent choices or variables in a given situation or system. In statistics, it often indicates how many values can vary while still conforming to certain constraints, like the total sum or average. For example, if you have five data points but know their average, only four can change freely; the fifth is determined by the others. In a broader context, it can relate to decision-making, social structures, or physics, where it describes how much freedom there is to move or vary without being restricted by other factors.
