TUTORIALS: Try These Examples First

This short tutorial will give you a feeling for how to use WINKS. It is not intended to be thorough, but simply to lead you through some common procedures. Begin WINKS by double clicking on the WINKS icon in Windows. The initial WINKS screen appears. Notice the parts of the WINKS screen. See figure 1.

Figure 1.1. Opening screen

At the top are the menu options (the menu bar), File, Edit, Analyze, Window, and Help. Below the menu bar is an icon tool bar (unless you turned it off in the program options setup.) These icons are shortcuts to commonly used procedures. Make note of the "Repeat" icon (shows several repeating pages) and the "Journal" Icon (notebook and pencil.) The "Repeat" icon allows you to repeat the last procedure you performed. The "Journal" option allows you to collect your analysis output from any WINKS procedure into a single file that you can use later to print or import into your word processor. The icons on the icon bar are:

Icon Menu Items on the Icon Bar

File Cabinet Icon - Open a file

Spreadsheet Icon - Edit data

Xbar Icon - Calculate statistics and display a histogram

Scatterplot Icon - Display a scatterplot graph

Charts Icon - Displays the First Impression Chart Gallery

Repeat Procedure Icon - Repeat the last procedure

Report Icon - Display or print a simple data report

Journal Icon - display the contents of the journal.

Help Icon - Display Help

Exit Icon - Exit the program

EXAMPLE 1 - Descriptive Statistics

This example shows you how to open an existing database, display descriptive statistics on a single variable, and display a histogram. Follow these steps:

Step 1: The Detailed Statistics analysis is represented on the icon tool bar by the ( X-bar) icon. Click on the X-bar icon. A dialog box will appear asking you if you want to CReate a database, Open a database, or Cancel the analysis. Click on the Open a database button. (You could also choose File/Open or click on the file cabinet icon to open a database file). The Open dialog box will appear. Select the file named EXAMPLE.DBF. (You may have to scroll the file list to see the EXAMPLE.DBF file name. Either double click on EXAMPLE.DBF, or click on example, then click on OK.) Notice at the bottom of the screen, a message tells you that the EXAMPLE.DBF database is opened.

Step 2: Once you have opened the EXAMPLE.DBF database, a dialog box will appear where you can choose a field name. Click on AGE, then on OK, as shown in figure 2.

Step 3: - After a few seconds, a screen appears containing descriptive statistics from the data in the AGE field. See figure 3. Scroll this window to view information off the screen. The viewer that contains the text output for an analysis is called the "View Results" window. Later, we'll also see a "Graphics viewer". The View Results Window (or "Viewer" for short) will appear following calculations for most analyses, allowing you to see the textual results of your analysis. You should become familiar with the options on this viewer, as described below:

Figure 1.3. Viewer showing analysis output

View Results Window MENU OPTIONS:

Exit - Exit the window. NOTE: This is different than the EXIT Arrow. The Exit button closes the View Results Window only. The Exit Arrow exits the program.

Print - Prints the contents of the View Results Window to a printer.

Clipbd - Place the contents of the viewer into the Windows clipboard, so you can paste it into another application such as a word processor.

Save - Save the contents of the View Results Window to a file.

Journal - Copy the contents of the Viewer into the Journal.

Graph - Display a graph appropriate to this analysis.

Step 4: Click the "Graph" button to display the histogram associated with this data. A screen will appear showing a histogram of the AGE data. Click on the "Bell" button to add a bell curve (normal curve) to the graph. (Figure 4).

The menu options on the Graph viewer are:

GRAPHICS VIEWER MENU OPTIONS

Exit - Exit the graph window. Note: Notice the difference between the EXIT Button in the Graph Viewer and the EXIT Arrow, which is the program exit.

Print - Print the graph to the printer.

Clipbd - Capture the graph into the Windows Clipboard, so you can paste it into another application such as a word processor.

Save - Save the graphic as a .BMP file.

+ (plus) or -(minus) - Change the size of the class interval for the histogram. This usually changes the number of bars on the plot.

Bell - Displays a bell-shaped curve over your data. (See Dixon, p. 66)

Counts - Displays counts for each bar on the histogram.

Distribution - Cycles through three options: No distribution displayed, Cumulative Distribution, and Cumulative Normal Distribution Displayed

Title - Allows you to specify a title for the graph.

Figure 1.5 Side by side output

Step 5: From the Window menu at the top of the screen, select the "Tile" option. This causes the two output windows (text and graphic) to be displayed side by side. Notice that the graph is resized to fit into the smaller window. (Figure 5) The View Results Window, also resized, contains both vertical and horizontal scroll bars, allowing you to view any part of the output report. You can still choose the button options in either the graph or report viewer. You can exit either viewer by clicking on the "Exit" option in the viewer window. When you begin another analysis, the contents of the current viewers are erased to make room for the information from the new analysis.

Step 6: This ends the first example. Continue to Example 2.
