What is the table value of 5 percent significant level in f test?

It depends on the degrees of freedom for the f-test.


Why is it impossible to compute a T statistic for a sample that has only one score?

A T test is used to find the probability of a scenario given a specific average and the number of degrees of freedom. You are free to use as few degrees of freedom as you wish, but you must have at least 1 degree of freedom. The formula to find the degrees of freedom is "n-1" or the population sample size minus 1. The minus 1 is because of the fact that the first n is not a degree of freedom because it is not an independent data source from the original, as it is the original. Degrees of freedom are another way of saying, "Additional data sources after the first". A T test requires there be at least 1 degree of freedom, so there is no variability to test for.


How do you find degrees of freedom for a chi squared test?

(r-1)x(c-1)


What are the difference between static degrees of freedom and dynamic degrees of freedom?

Mass and damping are associated with the motion of a dynamic system. Degrees-of-freedom with mass or damping are often called dynamic degrees-of-freedom; degrees-of-freedom with stiffness are called static degrees-of-freedom. It is possible (and often desirable) in models of complex systems to have fewer dynamic degrees-of-freedom than static degrees-of-freedom.


How do you use the F Test to find the sample size for two sets of data?

The data sets determine the degrees of freedom for the F-test, nit the other way around!

What are the 6 degrees of freedom an object has in space?

A rigid object has up to 6 degrees of freedom: 3 degrees of freedom of location: In both directions of x,y,z axis 3 degrees of freedom of rotation (attitude): pitch, roll, and yaw, rotation about the x,y,z axis.


How do you find degrees of freedom for a chi-squared test?

The degrees of freedom for a chi-squarded test is k-1, where k equals the number of categories for the test.

How do you find the degrees of freedom when using the t distribution to estimate or test the mean of a sample from a single population?

If the sample consisted of n observations, then the degrees of freedom is (n-1).

Is the Z-test the same as Z-scores?

No, the Z-test is not the same as a Z-score. The Z-test is where you take the Z-score and compare it to a critical value to determine if the null hypothesis will be rejected or fail to be rejected.


How many degrees of freedom are there for an azeotropic mixture?

By degrees of freedom, I believe you meant dimensions. Everything in this universe has 3 degrees of freedom.


Is T test similar to Z test?

no t test is similar to z test because t test ie used for unknown observation and z is for the medicne
