Calculating statistics
How do i calculate the mean salary, standard deviation etc with these numbers?
Is there a way to mulitply two rows in the statistics app like in a spreadsheet?

Salary (x1000) Frequenzy
(200, 300) 28
(300, 400) 42
(400, 500) 33
(600, 700) 14

Please note that the salary is in NKR not USD Wink

RE: Calculating statistics
Go to Statistics 1 variable. Put salary in column D1, put frequency in column D2.

Then in CAS, mean(D1,D2) and stddev(D1,D2) should do it.

Do the same thing, but then define your data in SYMB of the stat 1 var app (indep, and freq) and then press STATS in the NUM screen. That is the "normal" way to do it.

Tried it this way now and it works fine as you described it, i thought this was the way i tried in the first place but I must've done someting wrong in the SYMB view or something.
