Thank you for the informative video. I've tried the (DATA) function in the calculator, entering returns as X values and probabilities as Y, then computing variance and standard deviation using the (STAT) function. Would I get away with this shortcut every time, or am I missing something?
Yes, but you would need to input each of the variable combinations as observations the right number of times, corresponding to their probability of occurence, e.g. 40% would require you to make the input 4 times out of 10.
@@letmeexplaincfa Firstly, thank you very much for the reply, but when I do it this way my answer is b for some reason, yet I am doing it exactly as you said, and my mean or in this case Ex R is the same as yours
Your videos are really great and are helping me get through the CFA lvl1 books. How much % of the exam would you say that your videos cover?
Thank you very much. I think the content covers something like 5 - 8% of the Level 1 content but I have big plans to expand this channel in 2024👍

Brilliant, absolutely go with this shortcut and use it! It should be ok, as long as you enter the relevant inputs the right number of times :)
very helpful thanks
Nice 👍 Thank you
How did you get that E(RA) is 0.49% and E(RB) is 2.37%?
They come from the previous video in the Quantitative Methods playlist. Here's the link: ruclips.net/video/fLHwDy_pUM8/видео.htmlsi=6PGLMhLpkH5LFyBr
Is there a faster way to solve this with a ba 2 plus calculator?
Also, for the variance doesnt the formula include n-1 in the denominator?
Yes, but you would need to input each of the variable combinations as observations the right number of times, corresponding to their probability of occurence, e.g. 40% would require you to make the input 4 times out of 10.
Because you are not dealing with observations here but probabilities, there is no n or n-1

@@typicalgamer5560 ok, but the answer to the question is indeed B :)
