    commenting again because i CANNOT OVERSTATE how amazing these videos are. I've always gotten really good grades in math, but watching literally 2 or 3 hours worth of your videos has given me more understanding of actual concepts than I've ever had. Undoubtedly, you are the best teacher I have ever come across. literal lifesaver for my AP exam, and for my future math classes. I've never enjoyed math until the last few days, when I started watching your videos.

    So for the 2 proportion z-interval, when are you supposed to pool? Is it that you don't pool for confidence intervals but do/should for the actual test?

    • @mporinchak
      @mporinchak  6 лет назад +4

      Yes, you do not pool for a 2 sample z-interval becasue there is no assumption of a null hypothesis being true. You only need to pool in a test between two proportions where there is a null that they are equal. Also, the pooled value is only used to calculate the standard error and no where else. Lastly, it's also ok if you forget to pool for a test, as the results won't be that different and you can still get full credit on the test.

    Also, when it comes to determining degrees of freedom for t-tests, when you plug the data into a calculator's t-test function, the degrees of freedom are less than those calculated and they're decimals. I understand that one is a conservative estimate and the other is the precise value. On the AP test, is there one we should use over the other?

    • @mporinchak
      @mporinchak  6 лет назад +1

      An estimate is totally ok on the AP test. The precise formula for degrees of freedom is quite complicated and not worth the time to use. using one of the two estimates, either the degrees of freedom from each sample added, or the smaller of the two is totally fine.
