Yes, you can process it on a TI-83 or higher, your calculator can compute it for you. To do it your problem must include a list of data points. To enter the data on your calculator, push STAT. Then go to EDIT. In edit there is a chart. The top row says L1, L2, etc. If there are already values in your lists, you can clear them by going up and highlighting L1, press clear, and then the down arrow. That will clear the list. To enter data, move to the rectangular box under L1. Type in your first value and press enter. Continue to do so until all values are entered under list one. Next, press STAT. Move over to CALC and select 1-Var Stats. Press enter. A buch of data will pop up. The symbol on your calculator for standard deviation is Sx, and there will be a value listed. That is the standard deviation for your data set. Some other things that are good to know with the info we have produced: _ X = mean/average of data n = number of data points minX = minimum x value Q1= quartile 1 Med = median Q3 = quartile 3 maxX = maximum x value Sx = Standard Deviation And a Q looking thing and a X is (Population Standard deviation) "Qx"

The answer depends on what functions are built into your calculator. Read the calculator manual.
The standard deviation is the standard deviation! Its calculation requires no assumption.
Standard error of the mean (SEM) and standard deviation of the mean is the same thing. However, standard deviation is not the same as the SEM. To obtain SEM from the standard deviation, divide the standard deviation by the square root of the sample size.
Enter each data point followed by the E+ button. Ex: 1.052 "E+" 1.054 "E+" 1.054 "E+". After all data points are entered, press 2nd then the square root button. Ex: 2nd Square Root = 0.00115.
