    Dang! That is wonderful to hear that you think my work is a masterpiece. I really appreciate that because I do put a lot of time and energy into my videos.

      do you have a series on anova and modeling/testing in r studio

      what makes it a masteriece is that after each essential sentence or statement you take a second thus giving an audience time to understand

      Thank you so much for this, you've saved my life (and my grades). This is genuinely such a simple concept to grasp when explained like this - I wish all of my math teachers and lecturers had explained the logic behind these concepts like you do because I would have fallen in love with mathematics sooner.

      Saying your own work product is a “masterpiece” seemingly apropos of nothing (at least post it as a reply to a viewer comment) is going to make you appear a lot more arrogant than you probably are. It’s a cheap “social proof” advertising technique

    I use a variety of different software including photoshop, illustrator, HTML5, Final Cut, GarageBand and a few other products. Each video takes me a long time to create. My rule of thumb is each minute of video takes about 12 hours to create, so a 7 minute video takes me about 84 hours of development time.

      "1 minute of video takes about 12 hours".....U R exceptional!!!

    No one has been this good at teaching ANOVA literally

    • @vees_magic_barbell
      @vees_magic_barbell 3 ปีที่แล้ว +1

      Seriously! I'm taking second year stats for psychology and our uni brought in a PhD candidate guest lecturer for this concept (literally the most complicated part of the course) who took a whole hour to explain what this video did in 10 minutes 🤦‍♀️

    • @lawjef
      @lawjef 3 ปีที่แล้ว

      You mean apart from at least a half dozen other TH-cam videos? Literally.

  • @ThyMousa
    @ThyMousa 10 ปีที่แล้ว +95

    WOW, spot on man. So far your videos have been the cleanest, and most presentable for easy visual learning, and your explanations the most straightforward, practical, and logically applicable! Truly beautiful. You have a gift, don't stop, please!

  • @jamesanderson2939
    @jamesanderson2939 4 ปีที่แล้ว +1

    Seven years have gone by and this is still the best video out there for two-way ANOVA. Prove me wrong I'll wait
    (As in, this video is awesome... but if you can prove me wrong I'd appreciate it. There are some really impressive videos out there for linear algebra, calculus, etc that this doesn't quite compare to)

  • @katieb1996
    @katieb1996 2 ปีที่แล้ว +4

    You are deadset incredible. Our entire class is struggling with our lecturer who makes a lot of errors and is not good at explaining concepts. We have completely been reliant on you and are all planning to include this in our unit feedback so that the university may have a look and see what is expected of succinct teaching. Thank you thank you thank you

    this was amazing. i hated stats because the profs and teachers keep using big words and throw this ratio that ratio and whatnot right at the beginning.
    with your example and very clear presentation, i was able to understand the concept behind ANOVA perfectly, within minutes!

  • @WilliamSones
    @WilliamSones 10 ปีที่แล้ว +2

    It's a great introduction, It's been about 4 years since I last used two-way ANOVA and needed a quick reminder. I remember covering at Mach 7 during my course using algebra so I liked your gentle pace. The only suggestion I have for improvement is to provide better explanation of the concept of interaction otherwise great!

    I've watched all the videos on ANOVA one way, but somehow I am still confuse how does the ultimate result (reject/fail to reject) relates to the null hypothesis. What is the initial null hypothesis for the one-way anova example (level of stress)? thanks, you made things a lot simpler

    Is this correctly understood: The difference from 1-way and 2-way is; in 1-way anova you can only include 1 independent variable, and in 2-way anova you can include 2 independent variables?

    But I have some questions:
    1., is Two Way ANOVA the same that factorial ANOVA?
    2., for a experiment design 2x3 (factorial 2x3) the unique way for conduct a statistical analisis, is mediated for two way ANOVA? (with assumptions true e.g. normality).
