HP-25 Two Variable Statistics
Hi all. Am I missing something?
After I enter x, y data pairs, when I press the mean or standard deviation button, I only see the calculation for the x values. Is there something I’m supposed to do to calculate those for y values? Also, R0, R1, R2, and R7 were available. So, since I could enter x, y data pairs, why wasn’t the calculation for Σ(y^2) in one of the spare registers? Thanks. |
