    This is the most incredible UA-cam instructing channels to ever exist. I have been on the brink of so many mental breakdowns, and every time I turn to the Organic Chemistry tutor. This channel has saved my sanity, my grades, and my future too many times to count. Thank you so much for everything you do. You are doing a great service to the world by making these silly little videos. Thank you.

    Wow! Just wow! You explained this very well. You broke it down and explained the fundamentals, which increased my understanding of this subject so much. You did this all in 17 minutes while my professor just talks too much about theorems in an hour and 15 minutes and doesn't go over example problems too often. You are the best.

      @pakarmyisizindabad6206 2 роки тому

      I know you have passed your degree, but replying for those who will have the same question, when we are dealing with sample, we take 'n', and when dealing with population, we take (n-1), here the whole class is of 10 students, and we are dealing them, so this is population, if we take a sample of 4 students from whole class of 10, it'll be sample.
