First you have to set the calculator in STAT mode, presumably Standard Deviation or SD. The display should show a STAT annoucer to the top. To enter values use the key M+ (or the key next to which is marked DATA. The screen displays the number of data values entered so far.
To get the statistics you must use the keys marked with x bar, n, Sigma x, etc.

Help! My Sharp EL-531x calculator is not calculating correctly.

EL 531x - can't find a manual online, and I can't work out how to put an answer in the memory and then re-use it. Please help! Thank you!


If you insist on finding the exact model number in the title of the manual it is possible your quest will be fruitless. Just take any manual for an EL-531 and you will get lucky. Besides, most calculators of the same manufacturer perform operations the same way.
Anyway, here is a screen grab to solve your problem.
