Standard deviation and other answers

I can make a list(l1) and run the calc to get most the answers I need. But how do you do the same thing with a freqlist in addition to the first list?

Sample: list 1=25,40,60,75,93 freqlist=30,50,20,40,30

Thanks
John

How do I compute population standard deviation on the TI 84 plus?


Put the data into a list using whatever scheme you prefer. Press STAT right-arrow to bring up the STAT CALC menu. Select "1-Var Stats" and specify the list containing the data. You'll get a screen showing the various statistical values. The population standard deviation is designated by a lowercase sigma.

How do I get the variance on the calc.


The following is an example for the dataset {5,7,18}. This will generalize to any dataset that you would like to use.
  1. Enter your datapoints:
    Press "5", "SIGMA+", "7", "SIGMA+", "1", "8", "SIGMA+"

  2. Calculate the standard deviation
    Press "2nd", "sigma_(x n-1)"

  3. Square the standard deviation to get the varience:
    Press "x^2"

    If you followed the correct steps you should see "49" as your answer.

Standard deviation


pulse F1(CALC), F1(1VAR) and it goes to 1-Variable Screen and shows the following:
x-(mean): 49.3333333
Sumx:296
Sumx^2:15066
xon:8.78761755
xon-1:9.62635271
n:6

I guess that you wanted the x- and xon

Also are available in RUN mode through VARS, F3(STAT), F1(X), F2(x-) and F5(xon)

Standard deviation


Here goes if you still need this...

STAT, EDIT, put information into L1 if only one variable stats, but put info into L1 and L2 if it is frequency table stats.

Then choose Stat, over to CALC, 1, enter...if 1 variable stats then press enter again. If frequency table stats, then choose STAT, over to CALC, 1, 2nd, 1 [L!], 2nd, 2 [L2], enter.
