To perform achi-square test, you compare a sample’s chi-square to a critical value. To find the right critical value, you need to use thechi-square distributionwith the appropriate degrees of freedom. Thenull distributionof chi-square changes with the degrees of freedom, but in a different...

Chi-Square Distribution These tests are usually done to compare the observed data with the data that is expected to be obtained with a specific hypothesis. Degrees of Freedom is usually denoted by a Greek symbolν (mu)and is commonly abbreviated as,df. The statistical formula to compute the ...
different degrees of freedom will display different t-distributions. Calculating degrees of freedom is critical when understanding the importance of a chi-square statistic and the validity of the null hypothesis.
Degrees of freedom represent the number of free choices that we can make in a given situation. One of the hypothesis tests that requires us to determine the degrees of freedom is thechi-squaretest for independence for two categorical variables. ...
The content deals with: (1) Based on the velocity analysis and the unit vector set of velocity of kinematic pairs, this unit vector set can be rewritten into the form of velocity characteristic (VC). Hence, the VC set are defined, which is used......
