    We’re paying thousands to the universities that pay thousands to lecturers, just to learn statistics for free in videos like this. This guy is the best statistics lecturer ever.

    You are an absolute beacon in the darkness that has been my understanding and application of R , and you helped me remember all the stats from my masters a decade ago. In short, I couldn't have done my assignment without you. Love your presenting style and method of demonstration. Thank you for passing on your affinity with R!

    Although this isn't new to me, being at the end of my undergrad psych degree, I must say, this is the best introduction to statistics for University students I've ever come across (judged by pragmatism, conciseness, and spirit)

    Hi Greg. This video is the reason why I subscribed to your channel. Why?
    1) The pacing of the information is just right (it's fast enough that it doesn't 'drone' on and on) ... and the rapid pace only works because ...
    2) The zooming in on the where the audience's attention should be is VERY clear.
    3) You chunk the different parts of the lesson, which helps to know what is being worked on.
    4) You BUILD up on the final product, so the audience can see the incremental changes from beginning to end.
    5) You MINI lesson concepts that you suspect the audience may not have complete knowledge of (t Tests, log plots, linear regression)
    6) You save the in-depth explanation of certain sub-topics to other videos! Awesome. Focusing only on the lesson at hand.
    7) You managed to squeeze an hour-long concept into a 15-minute video. 'Nuff said.
    8) You didn't bother the audience with how to install R, R-Studio, etc. Thank you (this is probably just a personal preference).
    9) I'm a teacher. This make me want to explain topics that I teach better.

    When following video from 6:26 to 7:07 it will get the average of the average_life. So what i did was first group by country:
    gapminder %>%
    group_by(country) %>%
    select(country, lifeExp) %>%
    filter(country == 'South Africa' | country == 'Ireland') %>%
    summarise(Average_life = mean(lifeExp)
    BTW im using R version 3.6.3 can't update any futher in jupyter notebook.
    just put this as reference for others thank you. nice vid! :D

    This is really really great but far from being for beginners, when I was a beginner I did not understand probably 80% of what is being said here. You need to have a solid foundation in Stats to get this. Maybe this video acts a motivation for people to learn Stats and R.

    • @henriqueb8538

      I agree. I'm not from the programming field and the amount of time and energy I use learning R sometimes makes me wonder if learning it is worth. Should I be taking my hours of study to improve skills in a more compreensive software? I frequently think about that.

      Same here. I really enjoy watching your videos throughout grad school and now I'm working for the CDC :) Keep up the great work! This is the error I received.

      I have similar problem. I downloaded the package "gapminder" (1.9MB) but after it, I cannot open it on the global environment.

    As part of my job, I've spent a combined 7 years using JMP and Minitab for statistical analysis. I've starting delving into R and found it a bit of a headache to use (the luxury of having GUI's!), but R is free so no complaints.
    This was a great tutorial and you made it very easy to follow. I already knew the statistics (which you did a good job explaining) but it was good to follow the coding. Thanks!

    the statistical part is a bit unprecise and incorrec in a general contextt!!!

      Jonathan thanks for the feedback. I'm sure you are right I'm really a beginner with R and am not a statistician (hopefully my demonstration wasn't too far off though) 👀

    regardless from the content, it can be easily claimed that this video also a good example of “how to prepare a good video by simple visualisation”. big youtubers have to follow this guy. i watched lots of programming videos, i will lose my eyes while i was searching commond lines and mouse movement.. where is that mouse sign? are you in which window mate?
    thanks o lot for good presentation and visaualization of the video and R programming introduction as well. this will really help lots of students.

    I'm using R for about 3 years now and also work with it daily. Especially at the beginning it took a while until I found my way around. Your videos would have helped me a lot back then. However, will recommend your videos to one or the other, if someone asks me for some basics again.

  • @LucasCarvalho-fn8eu
    @LucasCarvalho-fn8eu 6 ปีที่แล้ว

    I was kind of mad by having to learn R since there's plenty of softwares doing the same stuff and I already know how to work with them. I also think that demanding programming skills in every single area is getting absurd, it's very stressful to be asked to be constantly learning new techniques and technologies at the same time you have a ton of work to deal with. But I'm not mad anymore! This video really shows fastly how R can be extremely useful and FAST to work with once you get familiar. And I was very impressed with the level of customization in the plotting. Superb video and awesome teacher!

    This lesson is gold. I am doing public health, and we mostly work with IBM SPSS but I decided to take it a step forward by learning R since I am more interested in becoming an epidemiologist. Do you have a full course on R for future epidemiologists? I will gladly buy your course.
