Thank you for teaching, you're one of my go to teachers here in youtube when it comes to math and stats. your explanations are simple and straight to the point and easy to understand!

You sure know how to put things into perspective for those of us fight for our lives in these online stats courses! !!!!!! I wish i could subscribe to you a million times!!!!
This man is the best tutor I ever had. I love his voice, l love the tidiness, love the calm way he explains and make problems look so easy to solve. I wish I could meet him in person. I am a teacher preparing for my GK Test to get my permanent teacher certification, I paid a tutor from a University, what a joke that "Doctor Harrington" is. I will never look for anyone different than JG The Organic Chemistry Tutor. If there is anything you need to learn or remember how to solve: Is here just ask the Organic Chemistry Tutor. Thank you so much JG you are truly the BEST!!!!
broooooooooo thank you very much. lecturer taught us for 110 minutes and understood nothing but just watched 12 minutes of your video and understood the whole topic
you’re The best tutor I could ever ask for . Thank you so much. I love how neatly you explain everything . It’s calm to watch and your voice is so soothing
Thank you for this video! Very easy to understand, you walked through the steps very nicely, and explained things simply. I was able to complete my homework because of your video!

oh muh gawd that was so tedious but absolutely taught so very well and thorough so I get it.....THANK YOU! My teacher is not so great at articulating stats...struggling w/ remote learning...anyone else....this page rocks!!
This is simply the best, i have being following all the videos you post and have found it simple to just let you do the explaination instead of other channels keep it up you are the best .
You are sent on earth special for mankind I wonder how your videos helping people around the globe . really I appreciate you a lot may the lord bless you and continue to strengthen your life span thank you very much great saint of mankind your channels is more helpful to me more than my lectures thank you sir I will continue to follow until I seeze my breathing.
You’ve helped me so much, I absolutely love your videos and teaching method! Could you also make a video about chebychev’s theorem? I would really really love a video of you explaining it....
Dear Tutor, You need uniform class interval i.e. of equal size, you've taken the last interval as 90-100 i.e. wrong either it should be 90-99 so that class size remains same or you should make the discontinuous class intervals to continuous class intervals viz. 49.5-59.5, 59.5-69.5, 69.5-79.5, 79.5-89.5, 89.5-99.5 and after this you'll get correct values for M. It goes wrong at 2:26 Hope you'll correct it.
Considering that these are grades and some individuals are capable of achieving 100%, wouldn't it make more sense to include 100? (Not trying to crush your comment, I'm just trying to gain more insight)
I noticed this too. For the ranges I would do 51-60, 61-70, etc etc. And then for your midpoint it's not 60-51, you're supposed to find the difference between the lower class limits. So it would be 61-51= your class limit = 10, then the midpoint is divided by 2, so 5. You CAN do this kind of thing with uneven class sizes, such as 0-60, 61-70, etc, where your lower class is a whopping 60 (midpoint of 30). You just have to multiply that frequency by that specific midpoint.
Great video. How do you solve the case where the lower or upper bounds of the first or last interval, respectively, are open e.g. "90 and above" or "less than 50"?

this is a wonderful work i enjoyed it in preparing for my exam,s

Thank you and loved watch all the videos . You explain better than my lecture.

I really do understand your video a lot..it's well explained
I really appreciate your videos so well explained
You have tought me how to learn to teach from others ! Thank you so much !
correct me if i am wrong, but in standard deviation i think we don't minus (-1) from N. formula is Fi(Xi-X bar) square / n
thats what my uni teacher taught too. im hella confused and got an exam in 8 hours
I like your teaching style so much! I got Math skills and English skills from you ! Many thanks !
