I didn't understand a single word my professor explained in a 3 hrs class....but in 10 mins....i understood the whole of it!
Thank you Sir!
Thank you for your valuable comments...
Please share it to all your friends and groups.
O u to right
Yes, youtube is the best teacher - as for the mainstream institutions, just pretend to respect them. Lol
Thank you for your valuable comments...
Great work, Professor⚔️
The best video ever for beginners from a social science background. Highly recommended. Thank you so much for the guy explaining. He has a talent to explain complex things in such an easy way to understand. God bless him.
This is a great appreciation for us and we are really happy that our efforts are in the correct direction. Thank you so much for your valuable comments 🙏
This is what we call talent.
Thank you so much for your valuable comments and appreciation!🙏
You're a lifesaver! I was having a hard time understanding my stats classes at university but you've made everything seems so simple! Thank you!
Wow, I am glad that it is so helpful for you! Thank you so much for your valuable comments and appreciation 🙏☺
Residuals are computed as (Observed - Expected) and you need to do more tests in order to make sure that your model is corect and stable (when use OLS). 2 important tests: 1 check if the residuals follow a normal distribution, 2 check for heteroskedasticity. On the other hand you explained well
After reading psychology for 5 years, today i learned regression from a youtube video. Thanks a lot, you are a gem.
Thank you so much for your valuable comments and appreciation!

Seriously , student need teachers like you sir. Thank you so much , in just 10 mins you explained in such lucid way ,all the concepts which my professor was unable to do even in 3-4 hr class.
Thank you so much for your valuable comments..
I am slow learner in maths. but you made it so simple to understand.
at times, practising by hand makes me lose the focus on what to understand because it is too slow and easy for me to get distracted. but ur way of showing in excel is very effective for me.
A huge thanks, man!!! This was so easily explained, you’re a legend!

i didnt understand a thing when my dr teach me and i understand in 10 minutes all this marvelous thanks.
That's great! Thank you so much for your valuable comments and appreciation!
Another nice tool of Excel is on the x-y scatter plot. You can add a curve-fit line of a more complex nature. Instead of just linear regression, you can also use exponential, logarithmic, and polynomial. It can display the resulting function and corresponding r-squared fit. Great when the data is correlated by something more than simple linear relationship.
Yes, you can see that in other videos in the playlist. Thank you for your valuable comments 🙏☺
Nice video sir...thank u so much for providing so much valuable informations.
Thank you for your valuable comments...
really interesting, every thing cover less than 10 min. amazing. thank you.
Thank you for your valuable comments...
Thank you so much to clear our concept of correlation and regression.
Thank you for your valuable comments.
very well explained
thank you....I got some ideas
Thank you for your valuable comments...
@@learnandapply you are excellent teacher what do use to design your lessons
That's the problem of "Professor" - he/she is a perfect learner, but not a good teacher. But thanks to yt uploader, many of them are good teacher!!
Thank you for your valuable comments...
this video summarized the whole concept. thank you
Thank you so much for your valuable comments.
Please share it with your friends and colleagues..

Thank you for your valuable comments and appreciation! ☺️🙏
This channel is worth 10 million subscribers. Most underrated channel.
🙏🙏🙏
Thank you so much for your valuable comments, views, and appreciation 🙏🙏🙏
The explanation was too perfect. I want to know the relation between the correlation and regression with the decision making concept
Thank you so much for your valuable comments and appreciation
Congratulations show direction and degree of relation between 0 and 1. Regression shows this and also how one variable changes due to change in another and numerical relation and prediction can be made
This was really a useful video (with Excel examples as well) so far I've found after wandering for 4 hours on RUclips.
Thank you so much for your valuable comments and appreciation 🙏☺️
Very easy
+Ram Madhale
Thank you for your valuable comments
Generally I do not react to videos easily. But the method chosen here was extremely helpful. Thank you very much sir. Can you please do a video of Types of tests eg: T-Test, Z-test, Chi square Annova ?? maybe you already have done that video.. if yes, please help me with it.
Wow, that's great!
Thank you so much for your valuable comments and appreciation 🙏☺
For the videos on mentioned topics, yes, I had already made it. Please visit the playlist named "Hypothesis Testing".
Jesus, this is the simplest explanation for many courses combined. Too good for me
Thank you so much for your kind words and great appreciation 🙏☺
Explained Quite Well that too in very short time with examples.
Thank you so much for your valuable comments.
Hello sir, wonderful explanation.please upload video on stepwise regression and logistic regression
Thank you for your valuable comments...
I had already published video on Logistic Regression. For Stepwise regression, I will do it on future.
You can see it in Playlist named_ Correlation and Regression Analysis.
Thanks for such a wonderful lecture! So can we conclude that regression analysis is the followup of the corelation analysis as to see how to variable are related?
Thank you for your valuable comments.
Yes, you can say that.
EXCELLENT Thank you very much; I truly appreciate your time, explanation, and effort to produce this wonderful video.
Thank you so much for your valuable comments. Please share it with your friends and colleagues...
Found our video whilst looking how to use logarithmic equations on excel to analyze data. Super content, learnt something easily than reading a book. Keep it up.
Thank you for your valuable comments...
In the example of the temperature to ice-cream sales, how would it be calculated if at a certain temperature people just started staying home instead of going out to get ice-cream?
Thank you for your valuable question. Well, it will be reflected in our regression analysis with R-square value. We might be needed to conduct nonlinear Regression Analysis in that case.
I.e always Based on prablethings( prediction)
Thank you for explaining this so well! Love the accent too!
Thank you so much for your valuable comments and appreciation!!
