@krish u explain way better than the PhD professors at University

[vishalmishra]

Hi Krish,

I really like your videos. Indeed you are doing a great work. This gives me motivation in my Data Science journey.

Just to put my thoughts regarding the probability calculation,

Total Area in the graph = 1+2+3 = 100
From the z score table we will get area 3 = 6.68
Now we are interested in 2+3 which we can get directly by 100-6.68 =93.32%

Thanks

[akakarun]

Nice explanation. It can also be calculated in simple way 1 - 0.0668 = 0.932

Then oneday years laters, may be a decade later comes a guy like Krish and within less than 1 mins erases a doubt longer than 1 decade. You are a Guru, the true beholder of the sanskrit word of removing darkness and, in this case doubt.

Sir, you have no idea how big a blessing you are ...thank you for your work!

[procrastinator]

hello krish sir, i actually studied about pdf in one of our btech subjects, at that time i only knew how to find the answer to the question using z score table but never understood the real significance of that, but today u made the concept clear and also its significance in real life .Thanks

[helalali]

I cant explain my love towards you...love you for your efforts 🤩🤩

[aashishchaubeyschannel]

Dude, you nailed it, I was just checking the resources to send to my younger cousin and ain't this the best when I know a thing or two in statistics! Great one!

[jatin]

without that symmetry part, if we directly subtract that 6.68 percent from 100%, we would have an answer = 93.32%

[SabujGhosh]

You could have just substracted the value from the table from 1.0

[dartistkuldeep]

very very effective way to understand someone, god bless you sir

[amolmolerakhi]

Thank krish sir, i got clarity in concept.

[ayselceferzade]

perfectly explained! Thanks Krish naik

[firta_banjara]

Hi Krish,
just wanted to ask question at 9:07, why cant we directly do 100 - 6.68?

[thalanayarswaminathansaipr]

Best Explanation EVER! Hats off Man. !

[kishanlal]

Nice explanation.... we can also get the answer by subtracting 6.68% - 100% ( = 93.32%) . As we don't require that 6.68%(students less than 60 marks) from our entire bell curve, we could just remove that 6.68% from our entire 100% bell curve. Correct me if I am wrong!

[pbanerjee]

Great job. Your sincerity shows. Wonderful effort.

[ajaynayak]

really its very interesting and I liked the way u taught....

[almadv]

Thank you for explaining why the z score is needed. Good going!

[MrJaga]

Hi Krish,
Could you please make a video on p test, anova, chi square test. How to use them and when to use what
