Shortcut computation sample skewness and sample excess kurtosis for HP12?

[Enlighten_me]

Is it necessary to memorize the formula of sample skewness and sample excess kurtosis?
Is it possible to easily compute it with a HP12C?

You needn’t compute them:

• Skewness: http://financialexamhelp123.com/skewness/
• Kurtosis: http://financialexamhelp123.com/kurtosis/

I checked the LOS and you are right. I actually don’t need to compute them.
0_o And wow! You really have everything the kurtosis and skewness summarized! Thank you very much!

My pleasure.

Yeah just remember leptokurtic is higher in the middle and fat tails. Like you lept high in the middle.

Haha Very effective! I see you are using mnemonics. Thank you for that.
If you have done that with other, I’d gladly want to know them.

Like a kangaroo: the Australian school of mnemonics.
And platykurtic is low to the ground in the middle, like a platypus.

You’re welcome.
That comes from an engineer with whom I worked years ago.
