Getting Started with SDA 3.5
Topics Covered in This Document:
Adjusting your browser for the new interface
Make sure that the main SDA window on your browser
displays the various frames so that you can see them clearly.
If necessary, try one of the following procedures:
- Adjust the size of the window
by dragging the borders.
- Adjust the size of the text
(select View -> Text Size).
If a window to "view" the variable on the page of search results does
set your browser to allow pop-ups on the SDA site you are using
(for example, the Berkeley SDA site is 'sda.berkeley.edu').
Some browsers interpret that window as a pop-up and block it
If you want to move the borders between the various frames inside the main SDA
you must first make the frames
by doing the following:
- Type 'about:config' in the address bar of the browser, and press the 'Enter' key.
- Scroll down to find 'layout.frames.force_resizability'
- Set that option to 'true', by clicking on that line
and then pressing the 'Enter' key.
- Go to the SDA study (or return to it, and reload the page).
- Put the cursor on one of the borders between frames, and drag the
border in the desired direction.
If the small 'Search:' box does not appear on the left side of your screen,
even though you have a "Search" tab on the top,
it may be necessary to clear the browser cache.
To clear the cache,
select 'Tools' then 'Clear Private Data' and make sure that 'Cache' is checked
before you click on the button.
Then 'Reload' the page, and the small 'Search:' box should appear.
Select a program or procedure from the menu at the top of the main
(if you want to run a program other than crosstabulation,
which usually appears when you start SDA).
After you select a program, the windows for variable selection
and for program options will change accordingly.
Most procedures also have additional on-line help specifically for that procedure.
Click on the 'Help' button that appears on the option screen
for the program or procedure you have selected.
The available procedures will include some or all of the following:
Frequencies or crosstabulation
Comparison of means
Comparison of correlations
Logit or probit regression
List values of individual cases
Recode one or more existing variables, and create a new variable
Compute a new variable
List and/or Delete the variables created by recoding or computing
Download existing dataset and/or documentation
Create and download a customized subset of variables
View the full codebook for this dataset
(Multiple codebooks are sometimes available)
Search the documentation to find the variables you want.
You can select variables for analysis in the following ways:
of the selected variable
into the desired target area of the program form
the appropriate button
-- "Row", "Column", etc.
Type the variable name directly onto the form.
the description of
the selected variable
by clicking the "View" button.
Append or Replace Mode:
For some analysis programs,
if a field on the program form already contains one or more variable names,
the copied variable name either will be
to the current
content or will
it, depending on the "Mode" setting.
(The default is to
replace the variable name.)
to variable names that have been copied over
to the program form.
if you have copied 'age' over to the program form,
you can add a range restriction by typing '(18-40)'
onto the end of the name of the variable, resulting in 'age(18-40)'.
Run the Program
After you have selected the program or procedure that you want to run,
and the variables to use,
specify the program options you want.
click on the 'Run' button near the bottom of the option page.
Select the Desired Options
The option screen for each program provides the user with many options
for analysis and for the display of results.
If you are unsure about the meaning of an option, you can usually
click on the option name, and a help screen will appear.
Run the Program
Click the 'Run' button to execute the program,
using the variables and options that have been
The label on the 'Run' button varies somewhat, depending on
However, it should be clear which button to click on.
View/Save the Results
The results of the analysis will appear in a new window or tab
(depending on the version and settings of your browser).
After viewing and possibly saving the results,
it is usually a good idea to close the window or tab.
A new window or tab is opened every time SDA generates analysis results.
Using the Older (Classic) SDA Interface
New SDA Interface versus Older "Classic Interface"
The new SDA interface (version 3.0 and later),
with multiple frames in one large window,
will generally be used when you start up SDA.
If you prefer to use the older SDA interface,
click on "Use classic interface" on the top line of the SDA window.
The older interface will also appear under any of the following circumstances:
However, problems #2 and #3 must be handled by the data archive
that hosts the dataset you are trying to use.
- The study you are analyzing does not have a variable tree
(generated by the codebook program).
- The data archive has set up the study to be run using the older
