All of this was put in tables to
make it easier to control the layout and
format.
Click on StatDisk icon on the Desktop
or Click Start, Programs, and StatDisk

Once this screen appears, click
Close and get started with the

Here are some of the options
available under the Data command on
the toolbar.
You should click on various ones of
these to see what it shows.
Click on the Help command for
information about what operations
each command will perform.
Likewise, you should click on
Analysis to see what operations are
available under that command.
The Sample Editor Window
4
should open automatically. If it
does not, Click on Data and Sample
Editor. This allows you to enter data
from the keyboard. To enter data from
a dataset, click Datasets and choose
the appropriate file.
Sample Transformations (under Data)
allows you to modify the data by using
arithmetic operations: +, -, *, /, Mod,
and Pwr. This means you can find the

sum, difference, product, quotient,
modulus, or power of the values in one
column with a constant or the values in
a column.
Choose the Source column, Operation,
and either Constant or Column. You
can also use Advanced Transform.
Then click Transform for the results.
While in the Data Window, you
5
may use Data tools to Edit column
titles or Sort the data from smallest to
largest value or delete columns.
If you need guidance, click the Help
button.

With data entered into Data
Window, go to the toolbar and click
Data. Choose the operation that you
want to use (here Descriptive
Statistics).
Click Evaluate for the results.

Window,
go to the toolbar and click Data.
Choose the operation that you want to
use (here Histogram).
Choose the column that contains the
data and the Plot options. Click Plot to
get the plot of the Histogram.
You may Turn on labels or Turn labels
off to show or hide the frequency
values for each bar of the histogram.

The Histogram in Frame 7 is a
Frequency (Counts) histogram. The
Histogram in Frame 8 is a Relative
Frequency (%) histogram.
Both of these histograms were created
with the Auto-fit option. User defined
with Class Width = 10 and Class Start
= 15 would produce the same
histograms.
This is a histogram for the data in Frame 4 above.
Those 5 data values are: 23, 34, 21, 23, and 42. The
frequency distribution is shown to the right.

With data entered into Data Window,
go to the toolbar and click Data.
Choose the operation that you want to
use (here Boxplot).
You are prompted to select the
Column(s) that contains the data to be
used for boxplot(s).
Click Plot. The data from the selected
column(s) are evaluated to form the
boxplot(s).
StatDisk has numerous sets of
10
data stored in Datasets. To use
these data in StatDisk, click on
Datasets and choose the appropriate
data set. It will be copied into the Data
Window and ready for use.

IMPORTANT: STATDISK version 9.5 and later now uses TEXT FILES instead of special .sdd files.

The STATDISK Sample Editor Window serves as a basic starting point for using STATDISK. Many of the modules in
STATDISK require raw data in order to perform a statistical analysis. The STATDISK Data Window allows you to
manually enter lists of raw data.
HINT: It sometimes becomes necessary to combine columns from different data sets. This can be accomplished by
copying individual columns from the STATDISK Data Window. For example, if you want to combine the third column from
each of three different existing data sets in the "Datasets" listing, open the first data set, then use COPY and PASTE (as
described below) to copy it into the second data set. Next, copy the two desired columns from the second data set into
the third data set.
Here are important notes about the use of the STATDISK Data Window:
OPENING A DATA SET: If using a data set from Appendix B in the textbook (except for the body temperature data), click
on the main menu item of DATASETS, then scroll down to the desired data set and click on it. The sample data will be
automatically copied to the STATDISK Data Window.
CLEAR: Click on the CLEAR button to erase all of the entries in the STATDISK Data Window.
COPY: Click on the COPY button to copy selected columns from the current STATDISK Data Window. The selected
columns can be copied into a cleared STATDISK Data Window, or they can be copied to other applications, such as
Excel or Minitab.
PASTE: You can PASTE data sets into the STATDISK Data Window. Those data sets can come from the STATDISK
Data Window itself, or they can come from other applications, such as Excel or Minitab.
SAVE AS A TEXT FILE: Click on this option to save a data set that is in the STATDISK Data Window.
DATA TOOLS: Click on the Data Tools bar to EDIT an individual column title or to SORT the values in an individual
column. The SORT option allows you to arrange the values in increasing order. CAUTION: Don't SORT an individual
column and then use a module based on paired data (such as correlation/regression or hypothesis testing with matched
pairs), because the rearrangement of the data will lead to incorrect results.

Document.
Within the Word document, Click on
View and Toolbars. You should have
at least the four shown on the left
checked for use: Standard, Formatting,
Drawing, and Picture.
You should have both Word and
Statdisk open to make the operations
easier. With the desired results on the
screen, press PrtSc (Print Screen) to
place that screen on the Clipboard.
Switch to Word document (Alt Tab).
Paste into Word.

With the handles visible, you can crop the screen to what you want. Click on the Crop icon,
move it over the handle in the center – top, bottom, left, or right. Hold the left mouse down
and move it toward the center of the picture as far as desired.

Click on the drawing to make the handles (squares) visible (Fig.4.0.2.1 on left).

When your mouse moves over the drawing, you get a four-headed arrows symbol or a twoheaded arrows symbol (Fig.4.0.2.2 on right).
The 4-headed allows you to drag and drop the drawing. If the 2-headed is horizontal, you can
resize the drawing to make it wider or narrower. If the 2-headed is vertical, you can resize the
drawing to make it taller or shorter. If the 2-headed is on a 45-degree angle, you can resize the
drawing and keep it in the same proportion.
You may also move it by using the arrows on the keyboard when the handles are visible on the
drawing. When you drag and drop or use the arrows to move the drawing, you cannot move it
except a specific amount that may not allow you to put it where you need it. To move the
drawing a very small distance, make the handles visible, hold the Control (Ctrl) key down and
use the arrow keys on the keyboard. Alternately: Make the handles visible, hold down the
Alternate (Alt) key and use the mouse to move the object.
You can PrtSc (print screen), Paste into Word document, Crop and/or resize the picture

before placing it where you want it in the document.
To get this effect, click the picture to get the handles, click Format, Picture, Layout tab and
choose tight and center.
