Thanks for your response @Mishab Abbaz. I can definitely do a video on skewness and kurtosis. However, I have observed that in practical terms, measures of spread used alongside graphical representation provide a stronger sense of shape (tails) and symmetry. Skewness and Kurtosis will largely satisfy an academic perspective. Let me know if you want me to take it up separately.
Sir.... please clear my query... why can't Geometric Mean and Harmonic mean be of negative values?? Like if we have negative values, we can still calculate it ... and we can also make amendments in the formula like adding one to each value then subtracting that 1 in the end.... "it can be calculated for negative values na" or else how can we calculate daily stock returns... they have negative values too... and Arithmetic Mean isn't suitable for it
Yes. For GM, the workaround you have mentioned is often used for special cases. Often we also do use a the concept of CAGR in such cases. In so far, as the HM is concerned, HM is used when we use "rates" which are almost always positive e.g. speed is a rate (2 numbers with different units). There are extremely special and rare instances when a rate can be negative e.g. internal bank interest rates in case of severe or impending deflationary trends. However, they are internal to the institution and does not involve the consumer directly. The treatments are a little different. Yes, sometimes the same workaround is employed here as well. Hope this clarifies.
The figure of 7.56% is the arithmetic mean for the column "Rate of Returns %". 27.08 is the (notional) average amount received across 5 years. The idea in this example is to convey that both these figures are inaccurate to depict the "Average Growth Rate". The correct method will be to use the GM for the calculation. The same gets clarified going ahead on the example.

Helped in clearing my exam easily :), So thankful
Glad it helped! Most welcome!!
Sir, can you Give an idea about skewnes n kurtosis

@@LearningPuree okey sir, I refer your channel for net/jrf commerce Preparation. I apreciate your initiative of experiential learning
Sirr... I don't know how to thank you... But really really gooddd
Glad it was helpful!
Thanks Sir. Cleared the concept. What's your profession btw.
Appreciate it. Solution consultant.
YOUR VIDEOS ARE VERY INFORMATIVE.. WHY ARE YOU NOT UPDATING MORE VIDEOS ?? LOVE AND RESPECT ..
Working on them ... More are on the way soon! Caught up in project work that takes up considerable amount of time.
Thanks. Your support is much appreciated!

Sir plz do on moments . iam your new subscriber. First time watched your videos. They are greay
Yes.. This is WIP.. Coming soon..
Nice video sir
Thank you. Do subscribe to the channel and share the videos for better reach with others.
Really useful information!!
Glad it was helpful!
Please sir how did you get 7.56%? You got 27.08 as the average in the first example when you showed that AM can be used in rate of returns
