Statistics Lecture 2.2: Creating Frequency Distribution and Histograms

[@MLeoM]

9 years later professor is still changing the world just with this video... Thank you, sir....

[@dalisabe62]

Dr. Leonard is a firefighter. He took the fire of subtle and boring details out of this subject and made it look like a breeze. This honorable professor deserves noble prize in teaching. He writes down and notes every little important (every point) in this class and cuts no corners leaving no chance for any student to be confused about any part in his magnificent lectures. He seems never tired or bored to make sure that his class understands and gets it. First, I thought that his pace was too slow and demanding, to only fall in love with his presentations and rewind the video to watch it or part of it over again if needed. Hats off to Dr. Leonard!

[@joanne1967100]

Thank you Prof Leonard. I am 49 years old, from South Africa and studying part time. Your lectures help me a great deal.

[@TheBestestKitty]

I made the mistake of taking my Stats 1000 class as "online only" Your lectures here are saving my bacon.

[@StaticBlaster]

I love bacon. lol.

[@Gigikelli]

Professor Leonard~ You are the BEST instructor I've had for stats. I am doing stats online all by myself. My class has no recorded lectures so you are helping me greatly and I am a student at the University of Idaho and I am finding my better instruction from you! Thank you so much for putting these lectures out here for us!

[@maggiesandoval2886]

Please never stop posting! I watched your videos and because of them I got 100 percent on my first quiz. THANK YOU!

[@siilentkiillah1]

Great lecture! i learned so much more from yu in this hour than i did with my professor of 3 hrs. Thank you so much!

[@sauravbhandari3273]

[@DvdRC9702]

I just transferred from a small liberal arts school to an ivy league, and my number #1 regret is missing out on professors like this. You're a blessing and are currently saving me from the worst professors of all time. Thank you so much.

[@rvalenta4]

Hey Mr Leonard, I wanted to wholeheartedly thank you for this super clear, logically organized course full of relevant examples. I'm starting economics major next semester and I never expected to revise statistics during the summer but man did I forget all of this stuff. Pity the teachers/professors in our country can't explain it the way you do, I would have gotten an A instead of a D.

[@sophyrules]

THANK YOU PROFESSOR LEONARD!!! you are saving my life with these lectures. I have a terrible teacher with an extremely thick accent and you are the exact opposite. You are one of the best teachers i've seen.

I am so glad i found your page you seem like an amazing professor I understood this entire lecture never taking statistics and It helped tremendously!!

[@selinamo6769]

As many have said in the comments below, you are such an amazing teacher and have saved my life. You explain things in such a matter that makes it easy to understand. Thank you. My stats prof is simply too lazy and just reads off slides and goes way too fast without going into detail. Thanks again!

[@thatdentalchickandherjourney]

You were my life saver professor Leonard! I was struggling to understand the concepts on my online Statistics class until I found your lessons in the middle of the night. I was desperate to complete my exam/project, thank you so much for the help!!!

[@lorilihime]

+Janet Moake I was foolish enough to think I could do the online course. My teacher doesn't have any form of lectures or explanations. Can be really hard. I found this earlier today and decided to start from the beginning. I am sooo going to ace my next exam!

OMG. Same here.

[@alliceson6464]

Can I just say, as a dyscalculic you helped me understand this so well because of your ability to throughly go through each step. Thank you so much professor

Just came across your video. I agree with all the comments. your so calm and not rushed. I just dropped my statistics class today because the teacher did not care if we understood the materials. I was only in the class for 3 days and frustrated. I'm losing 600.00 . Thanks for really caring to teach the material in a way that's understandable.

I want to thank you Professor Leonard! I'm a Los Angeles, California student and taking statistics at this moment. I came home today with a failed understanding of my first exam. I would say I got a D. My professor assigns our homework through Math XL which I despise! By God's blessings, I found your lectures here and determine to learn through this material another way. I look forward to virtually learning here and thank you for including the homework problems at the end of your lectures. May God Bless always and I'll be here in your channel for the rest of my semester!

[@glizzard1894]

Made the mistake of taking an 8 week college stats class online. I literally have the textbook for support and the textbook is the driest, most awful textbook I have ever had the misfortune of reading. This class makes sense. This is the best math teacher I have ever, well, watched. Suddenly the homework is starting to make sense. Statistics shouldn't make you cry. I've pulled my 65% up to an 80% in three weeks. Thanks, Professor Leonard!

I've been searching for an example of Sturge's Guideline for figuring the # of classes for a frequency distribution. The formula given was 1+(log n)/(log 2). If I remember correctly, the class size was 39, and I came up with 7.45..... Only whole numbers were an option, so I rounded up to 8 and got the answer wrong. Apparently I was supposed to round down to 7. Thank you for the video's they are really helping!

[@nickerz81]

this was great! It helps back the information I am learning in lecture. Quick question though, you have arbitrarily chosen 8 classes but no real explanation further as to how you would determine this if you have larger numbers. In my class we learned the "power of 2" method to determine the number of classes. Do you teach that later on in your lectures?
