do you use when df=212? Basically the standardized char max's out at 120 or infinity. I have df=212 and assume I should be referring to df=infinity when finding my t-value. Is this true or should I be using 120?
Thanks!
If the degrees of freedom in a t-test increase and as they approach infinity, the t-distribution starts looking like a normal distribution. So in this case we start using Z-scores instead of t-values because the t-distribution at this point looks almost similar to a normal (Z) distribution. Hope this helps.
