What is covariance ? What is the difference between covariance and correlation ? | Neeraj Sharma

To the point and easy-to-understand explanation of what is the covariance or
what is covariance in statistics. It would be better if you will see 'what is the correlation' before watching this, if not still you would be able to understand both covariance and correlation. In this video, you will also understand what is the basic difference between covariance and correlation. you will be very clear about that 'what does covariance tell us?'
To explain all things easily I have taken some easy-to-understand examples. The full video is in the Hindi language.

How to calculate and when to calculate covariance:

What is correlation:

I am not even sure the whole lecture is in English or not, but still this was clearer than other fully English lectures. Thank you very much!

You explained it as smooth as butter, Kudos :) & All the best in everything what you do !

brother...i search almost 2 hr bt not get the percept information about the correlation and covarience...bt by this 2 video it clear...thanx for this wonderful video....

[shaziakausar]

So somple and clear expiation well done

You deserve million views on this video...
Impressive & interesting way of teaching.

How large covariance means strong relationship between 2 variables. .. although covariance means how much 2 variables vary each other???

Excellent video Sir

Thanks best video short in time as well as concept clearing

[tanumishra]

If both the variables are independent in nature then what will be the covariance of function X and y

[tanweerashif]

0:06 - WRONG.
Covariance doesn't tell relationship between two random variables.
Covariance tells relationship between random variable and random variate.
