This was really well explained! Relating it to the same concept in physics was very helpful

Thanks Karl! The concept of Moments belongs to Physics and gets picked up in Statistics.

CORRECTION: Typographical error: The SD of 2.5 is actually Variance. The correct SD without considering it as a sample is square-root of 2.5 = 1.58. However, this DOES NOT CHANGE the essence of the context and the content.

Thanks, finaly. But I hope you do the same video with economic example instead of physics the next time... Thanks again

The "moments" as a concept is derived from Physics and not from Economics.

Can you plz do more videos about this concept of moments Like factorial, absolute moments and moments of bivariate random variables

@LearningPuree Жыл бұрын

Sure. However, the concept of 'moment' will NOT change. What needs to be understood is that a moment is around/about a certain defined point e.g. a mean. So, the video may effectively end up as a repetition of the concept. Thank you for suggesting the topic.

@nadasalah8973 Жыл бұрын

@@LearningPuree thx for ur response. I got ur point ,sir i want to understand the idea behind why we using the factorial or the absolute and when we do that it's like understanding the intuitive part behind these concepts. I hope u understand what I'm takin about, cuz my English isn't that good.

I don't understand the part where you made "the second moment independent of the first moment". It is independent in what sense can you elaborate?

@LearningPuree Жыл бұрын

Please see the formula for the second moment. We deduct the Mean which is the first moment. So, in a way we are removing the effect of mean in the calculation of the second moment.

@summy2607 4 ай бұрын

Second moment is 110 and 100 for the data sets.. given..i really don't understand..how . Moments is when you actually divide that by 4 .. but ut just the added squares..

@LearningPuree 4 ай бұрын

It is the squared distance when considered from origin as '0' (zero). Since the denominator is the same, it does not matter for the comparison. This was done only to simply and exemplify the point on shift of origin. The figures are correct. In fact when you move ahead in the tutorial you will notice the 2nd moment was also calculated using shift of origin to get 2.5 and 0 (zero) respectively for both cases. Hope this clarifies!

@Gangaprasad Tewary This format is meant to clarify topic specific concepts. Statistics & its application is a subject by itself and needs to be studied as a part of a time and resource intensive comprehensive course that has a commercial component. To say the least, even the bits and pieces component takes a considerable investment of time and resources to produce the content.

Thanks for pointing it out. It is a typographical error. I had written the variance value by mistake. The necessary correction has been made in the comments. However, with the correction the essence of the content and context DOES NOT change!!
