In statistics, the number of degrees of freedom is the number of values in the final calculation of a statistic that are free to vary. [ 1] Estimates of statistical parameters can be based upon different amounts of information or data. The number of independent pieces of information that go into the estimate of a parameter is called the degrees ...
A single rigid body has at most six degrees of freedom (6 DOF) 3T3R consisting of three translations 3T and three rotations 3R. See also Euler angles. For example, the motion of a ship at sea has the six degrees of freedom of a rigid body, and is described as: [2] Translation and rotation: Walking (or surging): Moving forward and backward;
In probability theory and statistics, the chi-squared distribution (also chi-square or -distribution) with degrees of freedom is the distribution of a sum of the squares of independent standard normal random variables. The chi-squared distribution is a special case of the gamma distribution and the univariate Wishart distribution.
The six degrees of freedom: forward/back, up/down, left/right, yaw, pitch, roll. Six degrees of freedom ( 6DOF ), or sometimes six degrees of movement, refers to the six mechanical degrees of freedom of movement of a rigid body in three-dimensional space. Specifically, the body is free to change position as forward/backward (surge), up/down ...
In many scientific fields, the degrees of freedom of a system is the number of parameters of the system that may vary independently. For example, a point in the plane has two degrees of freedom for translation: its two coordinates; a non-infinitesimal object on the plane might have additional degrees of freedoms related to its orientation . In ...
Six degrees of separation. Six degrees of separation is the idea that all people are six or fewer social connections away from each other. As a result, a chain of "friend of a friend" statements can be made to connect any two people in a maximum of six steps. It is also known as the six handshakes rule.

1.365. In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure ( CP) to heat capacity at constant volume ( CV ). It is sometimes also known as the isentropic expansion factor and is denoted by ...
