WebJul 10, 2024 · 7. Degrees of freedom can be defined as the number of independent ways in which the space configuration of a mechanical system may change. Suppose I place an ant on a table with the restriction that the ant can move only through a tube on a line along x-axis. Then the ant will have only one degree of freedom in three dimensional space. WebSo 9 degrees of freedom for our 10 data points. We just took 10 minus 1. So if we look over here, so for a T-distribution with 9 degrees of freedom, you're going to have 95% of the probability is going to be contained within a T-value of-- so the T-value is going to be between negative, so this value right here is 2.262, and this value right ...
