In my physics honours lab to check our "goodness of fit" we have to use the Chi-squared and reduced Chi-squared equations. For the Lab we use the text Bevington Data analysis and error reduction. I'm having a problem on determining whether or not my chi-squared values are good because...

Compute the chi-squared value for this, with each face and an expected frequency of 1500 Compute the chi squared distribution usingchidistand 3 as the degrees of freedom The problem is, this is returning nonsensical values. For instance, on a d4, if I input 6000 evenly distributed rolls,c...
Let’s look a the primes, genuine and fake, less thanN= 200. We’ll take the distribution of digits in the list of primes as the expected values and compare to the distribution of the digits in the fake primes. When I ran this experiment, I got a chi-squared value of 7.77. This i...
Can someone explain why the distribution of Chi-square values I'm getting (using Pearson goodness-of-fit test) doesn't match the expected Chi-sqaure distribution? The test seems in this case to be massively conservative...my type 1 error rate never gets close to the .05 alpha level...
