    This statistics video tutorial presents the idea of a histogram as well as a density plot.
    A histogram is a common plot to see, which helps describe the distribution of a single numeric variable. A (Kernel) Density plot may be less commonly known by name, but is a useful companion to a histogram; you may have seen the density plot without knowing their name.
    These plots are very useful in helping us to visualize and describe the distribution of a numeric (quantitative/continuous) variable. Here we will talk about what these plots display and why they are useful in statistics and in research.

    By the way, I love your way of presentation on the board. Putting board in front of you makes me see every bit of information. Love everything about it.
    DO NOT CHANGE A THING!!!

    Great videos for someone who wants to learn the basics...These are the best on CZcams, no videos were that much helpful.. Thank you!

    Your videos are so easy to follow. With them broken down into small "bites" I can choose how much or how little time I can spend each day. I also find that watching at least one a day keeps things fresh for me. Thank you

    I'm so grateful to have come across your videos.
    You explain them so beautifully and easily. And I can't get past the fact that you are writing everything in reverse and soo perfectly. It's as good as learning from you directly.
    I've never enjoyed studying so much before. Tried reading a book 📚 of statistics and it was okayish and confusing.. Your videos are done sooooo beautifully in every way. Verbal audio and visuals. I take screen shots in the end and it's as good have having notes for reference later. Thank you so much.
    Love your work. Just amazing.

    Before watching your videos I've faced difficulty in understanding some concepts. But after watching your videos ,those concepts became very easy. Thank you sir

    Under a density curve, the total area should be 1. So, in order to superimpose a density curve on a relative frequency histogram (such as one in this video), each bar of the relative frequency histogram should be further divided by the width of each bar, that is 10 in this video.

    DAMN !!!
    This explanation is top of the world!!!
    I love how you present this,, I mean we have all those techand software but this... This is the original and what I want to see, making me feels like I'm in a classroom

    Dear mister, another fabulous show back to the basic. Enjoy it every minute! 👏👏👏
    By the way, "You don't study art", typical excuse for not pursuing prefection... hahahahahaha🤣🤣🤣

      thank Leo! I will work on my art skills for the next videos for sure 😂

    My understanding has been that the bins should be 0-9, 10-19, 20-29 and so on. One should not have to choose which bin 10 year olds could be assigned as could happen in your example above.

    Sir, please tell us which book we should follow to compliment this course.

  • @Mindfulmeditationjourney24

    Thank you Very much

    for this type of graph, if you use relative frequencies, it would be much clearer to interpret and analysis what is going on in this data. Just a suggestion

  • @benpetro436
    @benpetro436 Před 2 lety

    if you were making a frequency table for temperature would the bins still start from zero?

  • @niteshtalukdar850
    @niteshtalukdar850 Před 5 lety +1

    sir kindly make videos on geometric, negative binomial dist. in R

    • @anaswahid8520
      @anaswahid8520 Před 5 lety

      You are right
      These videos are not uploaded on CZcams

    • @marinstatlectures
      @marinstatlectures  Před 4 lety

      we may make these one day...at the moment we haven't for a few reasons...the first is that they are eww commonly used...also, we felt that once one can work with normal, poisson, binomial, etc, that other distributions are a bit repetitive.
      but agree what it would be nice to have, and we may get to that one day, after we clear the queue of other videos on our list ;)

    you should not use arrow in your frequency graph for limited data Mr.

  • @elishaen3328
    @elishaen3328 Před 5 lety

    You better use normal position,mirrored made me feel dizzy

    • @marinstatlectures
      @marinstatlectures  Před 5 lety

      Elifuraha, Sorry that the video didn't work for you! unfortunately, the "normal position" would make everything reversed which I assume would be difficult for a lot of people to follow. writing on the glass that is the only way to present the material!
