I'm currently enrolled in a statistics class and am struggling. Normal distribution was the easiest part that I understood but almost immediately after, have gotten lost in the following material. I've found your lectures just yesterday and will be investing a lot of time viewing these videos as I've already learned something new from two videos I've watched. Your approach is very similar to my professor's, as she is very good, but with your videos you do dumb it down which is in some aspects, necessary. I'm relieved that I've come across your videos. Thank you for making them available to the public.
I know this video is redonkulously old but my god man! I'm halfway through my 2nd week of statistics for my BS and these videos are already a godsend! THANK YOU for posting these!
I am so glad to be back on your lectures. I used your calculus and differential equations series when I was on a physics degree, and now I have switched over to data science here you are again helping me with statistics!
I am very grateful I came across your videos Prof. Leonard.I am currently taking a summer class at a university and its one whole semester crammed into one month. Everyday is considered one week. I am so overwhelmed and lost on my third day. Watching your videos helps to make things easier. You are a godsend, thanks for everything.
Thank you so much for the stats series! The school I attend has a relatively awful math department, and often times students here pay money to teach themselves course material. I am so happy that you have decided to make these videos available to students of all ages everywhere! These first couple videos were just what I needed, as my stats teacher neglected to explain any of the terminology at all, and jumped right into stem/leaf plots, standard deviation, and the rule of fives in the first lecture. It's a basic stats class (251), so none of us knew what was going on at all! I have already started recommending these videos to fellow nursing students and friends, as well as other people in math classes ranging from algebra to calc. Everyone that has looked into them has found them very helpful and better than most of the lectures we get. Thank you so much! You've saved a ton of students butts here! All of us are so grateful to have your help.
I love this stuff and your way of teaching this stuff. "I must go on . . ." In just these lectures you have shown me that learning 'statistics' is not an alien encounter. You simply start with an understanding of why it is 'statistics' and its purpose. For me, the vocabulary and definitions did the trick. Thank you. I DON'T have a statistics example coming up -- but, "I must go on" with your Statistics Lectures. Thanks to you, my mathematical confidence is growing and I don't want it to stop.
I was doing calculus last semester and the was always that one guy that had a loud laugh and laughed at everything prof said. I always expect to hear that laugh, like the videos are weird without it😂😂. Oh and I passed calculus very well so I'm back!!!
I have went from failing pre-calc to passing all of calc, differential equations, and linear algebra all because of you and now watching these for fun! Thank you for everything that you do!
Thank you for your videos they are awesome I am a mom and college trying to graduate and I knew nothing about statistics and you broke it down to the simplest equation so that I can understand I am so grateful for your videos thank you Professor Leonard
I’m enjoying watching this as a review for a CLEP. I‘m familiar with the subject as I took HS statistics-Professor Leonard is easy to follow and quite knowledgeable. Very friendly demeanor!
Recently started your Pre-Calc series, and just started this one to augment a class I am taking at Harvard. It is already helping significantly! And love to see that after all these years you are still putting out wonderful content.
Walter McMain Well, good luck. I started stats this week. Its a 5 week course so looks like I will have no life during that duration. I prefer an A or a B but its to early to tell.
Get the vocab down, there are a lot of really subtle but important differences to various equations, some of it may even seem redundant at first but it will make sense later. Really get a hold of the concepts too, like that the Z-score(or standard score) is the number of standard deviations a value is away from the mean. It will help you with word problems and visualizing the data. It can be a really fun class, I didn't know there was so much you could extrapolate on data. If you're into histograms and confidence intervals, you'll love it.
OMG before seeing your lectures i thought statistic is a boring subject (H0) .......................but your lectures really helping in rejecting the null hypothesis .... Thank you
You good sir are going to be my lifesaver this semester and possibly help me keep my 4.0! God bless you and thank you for helping this make sense. Your videos are beyond helpful. 🙏🏻😊
You actually can do math with the nanometers of wavelenths that define colors of the spectrum so sorta yes you can average visible colors and get a complementary absorbed color
Awesome lesson! I just started a stats course and I want to make sure I have the introduction portion of it down packed before moving on to the harder stuff. Ty for the great explanations!
Generally 1.1 and 1.2 are combined in the introductory lesson, he covered both as I took a class from the same book. 1.3 introduces new information 1.2 is rehashing and building upon 1.1's lesson in more detail effectively he already did that at once with a detailed explanation.
17.27 , he was like "1st whole chapter is vocabulary" and swayed his hand like it was no reason.. BOI YOU AIN'T READY FOR WHATS COMING. lmao failed this class, and I need to retake it again, who else is studying sociology ??
Of course you can assign a number to gender, as well as you could assign a letter or shape but it's arbitrary, and used as a label. Gender isn't a hierarchical or continuous variable.
Colors are additive to create new colors. Ask a lighting director. It takes three lights to create white light. Not the same for paint. In paint, and dyes, the pigments combine. The human eye only sees the color that is NOT there. A light source is absorbed by all the colors in the pigments, reflecting back to your eye only the pigment that is not there.
I hate to say this, but you CAN subtract color from color and get a different color,,, In Fact, my cosmetology taught me how to do hair color using an algebraic system of addition, subtraction and equations. One CAN subtract blue from green and be left with yellow. You can subtract yellow from orange and be left with red... so this color example, I do not think can be put in an ordinal category if you are trying to say that one cannot be subtracted from the other. ALL hair color that a cosmetologist uses are numbered. For instance, there is 1-11Red, 1-11Brown, 1-11Blonde, etc.
The differences in color ARE meaningful and can also be categorized by orders. Also, my bank account can go into a negative status. So, some of these examples are kind of confusing for me. I have had down to negative $300 in my bank account before. One slight drop of color can change the entire desired outcome results into a totally different result... I think that means A LOT ;) There are scales in colors and tones.
Yes it can be substracted, but as long as you care about visible color, the difference doesnt tell you anything. Visible spectrum is ~380nm (purple) - ~740nm (red). If you substract purple form red ie 740-380=360 (lets say its visible purple), you would be saying purple is purple away from red. Doesnt make much sense.

26:00 unless temp is in Kelvin. Love these videos
Yea temperature is really bad example, at least as long as you understand physics.
These students don't realize how lucky they are. My Stats Professor is dead inside while she's teaching, it's boring as hell.
He's amazing. I did dual enrollment with him and I wish I could have him as my professor for the college I'm going to.
I can definitely understand what you are saying cause I have same dilemma.
What a coincidence, I’m dead inside learning statistics too!

Time to piledrive a bunch of these videos just before stats final!
Walter McMain How did the final go? You ace it?
Walter McMain I have no idea yet, I gotta email my teacher sometime this weekend after they've had a chance to grade it. Will know soon hopefully :D
I'm a moron though, so I'm not expecting anything impressive like an ace. Maybe a casual floundering by, but not ace no. That's not me.

"You can't put a quantitative value on gender." The ancient Chinese did, associating odd numbers with masculinity and even numbers with femininity.
Of course you can assign a number to gender, as well as you could assign a letter or shape but it's arbitrary, and used as a label. Gender isn't a hierarchical or continuous variable.
In a sample how many males and how many females, would that not make it quantitative data
We can sub the colors on the basis of wavelength
Hi sir how r u
I love and like statistics and with u r lecture.
You are one in a trillion, u are wonderful, I'm so lucky for getting your videos.
What is there in Statistics Lectures 1.2 and 1.4..just curious..
Did a fly pass by, I was looking for it in my room.
10:00 discrete data
Hey Professor Leonard, nice lectures. Just a heads up, colors can be ordered according to their wavelength, frequency, intensity.
Do you know what book hes is using?
Had no clue , you have stat videos too.. glad i watched your calc 2 videos, really helping me for differential equations.
Colors are additive to create new colors. Ask a lighting director. It takes three lights to create white light. Not the same for paint. In paint, and dyes, the pigments combine. The human eye only sees the color that is NOT there. A light source is absorbed by all the colors in the pigments, reflecting back to your eye only the pigment that is not there.

Elementary statistics by Maria Trulio
Wonderful and easy to understand. Thanks a lot!!
Is there any recommended book I can follow through with your lecture?
Handsome professor with really helpful videos!!
24:40 I think color can be subtracted as they have a corresponding wavelength interval on the spectrum.
Yes, this is why the sky seems blue, although we are hit by white light(sum of all colours).
Yes it can be substracted, but as long as you care about visible color, the difference doesnt tell you anything. Visible spectrum is ~380nm (purple) - ~740nm (red). If you substract purple form red ie 740-380=360 (lets say its visible purple), you would be saying purple is purple away from red. Doesnt make much sense.
