Chi Square Test Degree of Freedom
 
10:44
Chi Square Test Degree of Freedom This video explains about how degree of freedom is determined when using chi square distribution and also why n-1 is commonly used instead of n to compute the degree of freedom in chi square distribution. Chi square distribution is the distribution of sum of square of a standard normal random variables. The degree of freedom depends on 2 factors: number of points in the sample, and the number of parameters required to be estimated.

Chi-Square Distribution Degrees of Freedom Definition (Technical)
 
10:12
Chi-Square distribution Degrees of Freedom explained using definition (Part 2) In this video, you will be learning about determining degree of freedom based on the definition of chi square distribution. Chi square distribution is obtained when you have sum of random variables X(i)'s which X(i)'s follows a standard normal distribution with mean (0,1). The number of points in sample and number of estimated parameters determines the degree of freedom. Chi square distribution is used in many tests, such as the chi square goodness of fit test. A lot of times when we performed chi square distribution, the chi square test degree of freedom is usually n-1 instead n. This is because our X(i)’s are sampled randomly not from a standard normal, but a normal distribution with mean mu and variance sigma^2, in which my mu is unknown. Because we have to estimated mu, as a results we would remove away one degree of freedom from the chi square distribution. Chi square distribution, unlike normal distribution, is asymmetrical. The application of it is wide, but it is important to know the fundamentals of chi square distribution before performing any goodness of fit test using it.

Casio fx-9750GII - Calculating Chi Square Upper Tail Area

Calculate the upper tail of a chi-square distribution on a Casio 9750 graphing calculator (http://amzn.to/1AVxr78). For more free statistics resources, visit http://www.openintro.org. Also, check out our free intro statistics textbooks at http://www.openintro.org/stat/textbook.php - - - Approximate script: To find the tail area for a chi-square distribution, first navigate to the Stat section using Menu and then hitting 2. Then hit F5 for Distributions, F3 for chi-square distribution, and then F2 for chi-square cumulative distribution. If needed, switch to enter the data as variables. In the first problem, I'm going to find the upper tail area for a chi-square distribution with 5 degrees of freedom for a cutoff of 12. So I'll punch in 12 for the lower distribution cutoff, and then I'll punch in a really big number for the upper cutoff. A value like 10000 will do just fine for almost any situation. Lastly, I punch in my degrees of freedom of 5 and hit execute. I get an answer of about 0.0348. I'll do one more problem: the upper tail when the degrees of freedom is 1 and the cutoff is 2.5. Here I get an upper tail area of 0.1138. If you liked this video, give it a thumbs up below and subscribe. Thanks for watching.
