Thanks so much. You saved my statistics course. I found it really better than our lecturer at Imperial. Now I can't believe I paid 30,000 to them.

Always my best channel to learn Stat

The tutorial collection is really good! It covers concepts that need hours of continuous lectures in college in a much simpler way. Thank you for the knowledge.

Thanks. It is so nice to have my efforts appreciated.

hello Dr Nic, i'm very new into your channel, and I just noticed that some of your videos are like 9 years old, but I am very grateful that you are still uploading a lot of knowledges... I want to say thank you for helping all of us to learn statistics. i'm now in an early year of engineering college which is non Math/Statistics major. But i suddenly have interests in AI and Machine Learning, which are out of my faculty scope of curriculum. So i started to self-learn from books, internets, and luckily i found your channel. 😁 (i mean why didn't I find your channel like years ago 😭) I hope i can always enjoy every knowledge from now on, and can build a strong math and statistics fundamentals through your Channel, so I can pursue in AI/ML career. Thank you very much Dr Nic! 😊🙏

So, it means we can reject the null hypothesis if the p is 0.02? Also, thank you a lot Dr.Nic, you made Statistics more enjoyable for me! Edit: I cannot access the web content anymore and it said 404 web page not found. Could you kindly check that as well?

You ARE amazing!

My favorite scene from any if your videos was when you said “In general,” and had a picture of Napoleon (I think). Also, when the question was “Male or Female” and the researcher was yelling at the subject “Make your choice!”

I know. My son used to edit my videos, or put a final funny touch on them and he has a real talent for it. He makes me laugh out loud at my own videos. I'm not as funny, though I do try to keep a light touch. I'm hoping my clear explanations will keep people coming back.

When sample size is 250 and population sd is unknown which test should i use tscore or z score ?

@DrNic

4 жыл бұрын

With a sample that size there is no difference.

My book says that when using the t-distribution, one should replace that s/sqrt(n) by s/sqrt(n-1)

@DrNic

3 жыл бұрын

This is not something I've heard of. For sample standard deviation you use n-1 in the denominator as opposed to the population standard deviation. But for the standard error, it is customary to use s/sqrt n. Perhaps you or the book have those two calculations confused?

@renjing

3 жыл бұрын

@@DrNic Ah, maybe it was me who got confused. May I check with you: Now after we calculate the sum of squares for the sample, we divide it by by (n-1) instead of by n? (and then take its square to get sample standard deviation) May I ask one more question, please: In this example, do we have to know that the population follows a normal distribution to use the t test, especially when the sample size is small?

Like the video before I’ve finished it?
