Getting the Standard
Deviation from your calculator:

 

I have used the following data set to get the mean with
several different calculators.

 

1, 1, 1, 4, 7, 7, 7���
standard deviation = 3

 

Current Calculators that I have in my office:

 

  • Casio fx-115MS
  • Casio FX 115 ES
  • TI-30Xa
  • Ti-30XIIs
  • TI-36x
  • TI-83, TI-83Plus
  • TI-89

 

 

There are hundreds of calculators on the market that find
the standard deviation.If you do not
have one of these calculators, you have several options.

  • Look
    at the manual for your calculator.
  • Go to
    Google and type �standard deviation with __________ calculator�.

  • Click on the Mode button twice until you see
    �SD�. Select 1. This puts the calculator in Statistics Mode.
  • Enter the first number, 1.
  • Hit the M+. (n= 1 will appear in the window)
  • Enter the second number, 1.
  • Hit the M+ key.(n=2 will appear in the window)
  • . . .
    . .
  • Enter the last number, 7.
  • Hit the M+ key.(n=7 will appear in the window)
  • Hit shift, 2. (This invokes the S-Var option.)
  • Hit 1 for the sample mean. Hit Enter.
  • Hit 3 for the sample standard deviation that
    we will use in class. Hit Enter.

  • MODE button
  • 3 for STAT
  • 1 for 1-VAR
  • Enter your data 1, enter, 1, enter, etc
  • SHIFT 1 for [STAT]
  • 5 for Var
  • 3 for population standard deviation or 4 for sample
    standard deviation.  Also, 2 for mean. 

 

TI-30Xa

  • Enter
    the first number, 1.

    x2 (by hitting the 2nd key you are actually
    selecting the x-bar written above the key.) This gives you the mean.
  • Hit 2nd
    sqrt(x). This gives you the sample standard
    deviation which we will use in class.
  • Make
    sure you turn your calculator off and on for new data sets.

  • Hit 2nd, Data (this means really that
    you are entering the STAT menu)
  • Select 1-Var.
  • A blank screen will appear. Select Data again. X1
    will appear.

    down, you will see FRQ=1. Scroll Down.
  • . . . .
  • Enter the last number 7. Scroll down, you will
    see FRQ=1.
  • Select STATVAR.
  • Use the right arrow key to get: n, x-bar, and sx. If I ask you to compute the standard
    deviation by hand, I am looking for sx
    not the other listed values.

 

TI-36X

  • Hit the 2nd and x<>y button.
    (This puts us in Statistics 1 mode.)
  • Enter the first number, 1.
  • Hit the Σ+ (Sigma+) key. (1 will appear in
    the window)
  • Enter the second number, 1.
  • Hit the Σ+ (Sigma+) key.(2 will appear in the window)
  • . . . .
    .
  • Enter the last number, 7.
  • Hit the Σ+ (Sigma+) key.(7 will appear in the window)
  • Hit 2nd x2 (by hitting the
    2nd key you are actually selecting the x-bar written above the
    key.) This gives you the mean.
  • Hit 2nd sqrt(x).
    This gives you the sample standard deviation which we will use in class.
  • Make sure you turn your calculator off and on
    for new data sets.

  • Hit 2nd
    and click on 0 (by hitting the 2nd key you are actually
    selecting the catalog written above the key.)
  • Select
    LN (You are actually selecting the S in green.) This skips you through the
    catalog through the s�s.
  • Use
    the arrow down key at the top to scroll to stdDev( . Hit Enter.
  • This
    will take you back to the main window. Finish off the statement, so that
    it looks like this below.

stdDev(1,1,1,4,7,7,7)

Notice the insertion of the curly
brackets. These are very important. After the above is entered, hit Enter.

 

TI-89

  • Hit
    the Catalog key.
  • Select
    3 (You are actually selecting the S in purple.) This skips you through the
    catalog through the s�s.
  • Use
    the arrow down key at the top to scroll to stdDev( . Hit Enter.
  • This
    will take you back to the main window. Finish off the statement, so that
    it looks like this below.
