TI BA II Plus Geometric Mean

In this video I will show you how to calculate the geometric mean using your TI Business Analyst financial calculator. In principle this is very easy to do however the calculator does it in a slightly clumsy way.

Can I just say, thank you so much! What a quick easy perfect video for exactly what I needed.

Video is incomplete because it does not address how to contemplate negative numbers, which is something very frequent when dealing with rates of returns. To do this, you'd need to use the following formula:
geo mean = [(1+r1) x (1+r2) x ... (1+rn)]^(1/m) - 1

where 1, 2 and n are periods. r1 is the rate of return at period 1; r2 is the rate at period 2, etc.
m is the total number of rates,

I have been trying to figure out how to do this for almost a week. Thanks for uploading this video.

Thanks for sharing your expertise with us. This was very helpful.

Great explanation to the math as well. Thank you!

Very helpful, thanks a lot. I have a TI-30XIIS and realized that it requires a parenthesis in the set. So: 4, then 2nd, (nth root) then (7*5*9*4) equals the correct answer. I'm using a TI-30x IIS.
Thanks again!

You REALLY had to use 1/x just to find out what 1/4 was...? Really? Spoiler: 1/4 = 0.25. Simple math.
