THANK YOU, GOD BLESS BROTHER! I pray for whoever reads this to excel through there current math class if you're facing any trouble!! Strive now and shine soon!

I think it should have been noted that there are two types of standard deviation: sample and population. The method used here is sample standard deviation because it divides using n-1. Population standard deviation divides using n. Which method used depends on the data being analyzed.

As a mother going back to college in her 40's, I was struggling with Statistics. My college course is online which makes getting help from an instructor very daunting. I appreciate what you do very much! Everything just sort of clicked and made sense while watching your video.

I don't even know how else to tell you "THANK YOU"



You're my superman... You literally saved my grade 😭😭😭

I always appreciate hearing that my videos are helpful. Thanks!

Thanks for the question. The 6 is the number of observations (n).

[statisticsfun]

Thanks for the compliment. I always appreciate the feedback. By the way I am getting ready to load a video about degrees of freedom (n-1) for standard deviation and variance.

Learnt more in 5 minutes than I did in hours of classes... thanks!

I have been studying for a comprehensive math exam covering algebra to calculus and this is by far the most helpful video I've watched. Excellent job!

[statisticsfun]

Wonderful! That is my goal to help students learn, so I appreciate your comments.

This helped me so much, my professor made it into something 10x harder thank you

[aneshaberry]

This video is 12 years old at this point, yet it helped me sooo much! If you're still out there doing these videos, I just want to tell you thank you! Before than any textbook can explain!

[timelesstovy]

I learned an entire unit in 5 minutes. Short and easy to understand, thank you !

It's been 30 years since my statistics class. I was hoping to refresh my memory so I could help my daughter.  I'm going to send her to this tutorial (and any other's you have posted)!  So easy to understand. Even your tone of voice says "you can do this!"

[Jacqueline-bmdi]

Wow! Thank you so much! I have been so confused for the past few days on how to figure out the standard deviation, I knew the formulas and procedures but you just explained it so incredibly clear and patiently. You are so amazing and you get a 10+ rating on teaching, thanks so much for posting up this video. Amazing tutorial!!!! (This is coming from a person whose weakest subject=MATH!).

Great video, one of the very few on youtube that put everything into simpler terms. This was extremely helpful.
