How do I calculate means, variances, and standard deviations?

Use the command "summarize." You can simply type "summarize," in which case you will get means, standard deviations, and so forth for all variables in memory. Or, you can type summarize VARNAME which will give you a summary of the variable VARNAME.

Also, add the option detail, as in "summarize, detail" or summarize VARNAME, detail to get various percentiles. Top of page. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
