You're literally getting me through my data analytics masters way better than the lecturer does. Thank you!!

The quality of these animations and explanations have no comparison. The colors, font and characters used have a nice effect in the learner.

I have never been seen such a perfect guide, thank you very much for your hard work and highly appreciate it. And I have one suggestion that could you please continue to advance statistics and experimental design?

@mariaponomarenko3006 3 года назад

this channel is perfect, I wish my uni professors had taught me like that

@sexystranger6730 4 года назад

This is the best playlist for someone who has no prior knowledge of statistics like me. Thank you so much 😀

The best videos on statistics I've come across and trust me I've come across many. Keep up the amazing work.

@elizabethawa6351 3 года назад

the best there is especially if you are brand new to statistics like me. I will advise anyone to take it before enrolling in statistics

@zakarias86 4 года назад

Thank you so much for the straightforward and helpful videos! They are extremely enlightening! Please please keep enlighten us with your videos! There are so many subjects that we hugely need to understand in a such flawless way in the data science field.

I went to your website. It's down due to no funds. You are providing excellent content at no cost. I am from Afghanistan and I make just enough to support my family or I could help you on monthly basis.

@KashishSolkhiya Год назад

one thing i would like to ask that why you state that when determining correlation , explanatory and response variable are not necessary .

@jatinab Год назад

Excellent

@haneulkim4902 3 года назад

Thanks! One question, say I have 3 groups and want to see relationship between `GPA` and `study_time` to do this I calculate R for each group and get R = 0.5, 0.3, 0. Can I conclude that group1 has more sensitivy towards `study_time` which implies group1 gain most gain from studying?

@ajitkumar15 4 года назад

What are disadvantages of correlation.Which concept of statistics helps us to over come this disadvantages ?

@aniawo5119 Год назад

Sorry to bother, but how come that when I calculate SD standard deviation sx with excel, manually - it gives me 7.57 and, and when the same data pluck to the SD function on excel it gives me 8.28? I have checked few times, I can't find a mistake in my calcs :( the same for xy. When calculated it is 30.05, but when SD formula used in excel it is 32.91. What am I doing wrong?

@Urmapleleaf 2 года назад

Heya! Could you explain what kind of caclulations did you do during the simplification cuz Im lost? At 6:24. Thank ya!

@jr.gilitwala 3 года назад

@deimys1000 4 года назад

how did you calculated R .. how did you got r= 0,602. Ya missed lot of calculating steps.. what divide or multiply from what... because I dont know.. what / how..

@Simplelearningpro 4 года назад

Hi, so in the calculation for r, most of the steps were included in the green box at the top of the video. This is how you will know when to multiply and divide. Each step in the table is used to help us calculate the value of r with respect to the formula that I provided in the video. If you follow along, you should get the same answer. I hope that helps. Additionally, I would like to say that this is a very old video of mine that I created 5 years ago. I will be re-doing this video in the future since I assumed that each viewer remembered how to calculate the mean and standard deviations, and the truth of the matter is that people tend to forget and it's nice to have a review on those topics. But for now, you can look at my previous videos on how to calculate the mean and standard deviations for each of these variables. If you have any other questions please let me know, I hope that helps!

@MissMiniLila 3 месяца назад

Isn't the standard deviation 8.29?

@joyyang9396 4 года назад

even in a strong correlation would you also say there's an explanatory variable and response variable? But I learned that correlation doesn't mean caution.

@Simplelearningpro 4 года назад

Yes, correlation does not mean causation even if there is a strong correlation. Hope that helps.

@joyyang9396 4 года назад

@@Simplelearningpro thank you for answering, just to clarify this: both experiments and observational studies have explanatory variable and response variable, but in observational study the casual between the variable doesn't necessary exist?

@Simplelearningpro 4 года назад

@@joyyang9396 That is correct, both experiments and observational studies have explanatory and response variables. The difference is that in a properly conducted experiment, we can prove whether or not the two variables has a true relationship. Whereas in an observational study, the relationship is just a correlation and is just "casual" like you mentioned and we don't know if the relationship between the two variables is a real one.

I'm basically only able to focus on this if I'm playing some sort of music soundtrack behind it; Alien Covenant was the soundtrack I used for this video. Worked like a charm
