Four semesters of graduate level statistics, and you accomplished in 10 minutes what four different profs failed to accomplish at all. Thank you!

No better explanation than this one. Can't thank you enough Dr. Piers. You're an exceptional instructor with the ability to clearly, precisely and simply explain very complex statistics topics. God bless you. Much appreciation from Uganda - East Africa.

I'm doing a stats class now and I understand more from this 10 minutes than the whole lecture on it. Much thanks

Watched this three times and finally I understood this. The best explanation I have found on this topic, no doubt!

Most clear explanation on this topic I have seen on youtube. You've earned yourself a subscriber.

Thank you so much, this is a wonderful tutorial. I am a TA for a data analysis course and was having the hardest time figuring out how to emphasize the difference between SD and SEM. You did it very clearly and simply!! You just saved my students from a very confusing lab explanation :)

[cajogos]

Really good refresher to these statistics ideas, I had completely forgotten what standard deviation and SEM was! Thanks a lot!

[soknya]

I need to watch it twice to confirm my understanding. Thank you for a clear explanation

[akshu]

Sad that I watched it too late. But as it is said, better late than never. Amazing video. Now, I will never forget the difference. Thank you.

[devong]

You have a gift. Needed to brush up on a few of these for a class and this was concise yet coherent. Thank you so much!

Excellent breakdown, thank you for your service.

[chitritaghosh]

Thank you very much for the video. I am a medical student. I needed a understanding of the difference between SD & SEM for community medicine. Your video helped me a lot...
