Sawtooth Software: The Survey Software of Choice

How Lighthouse Studio Works

1. Compose Survey

howwebworksOnce you have installed Lighthouse Studio and have it up and running, you are ready to compose a web survey! Start the program and go to File, New Study and create a new study.

As you compose the study, Lighthouse Studio creates study-specific files in your study directory on your local computer.

2. Load Survey Onto Web Server

When you have created your web survey, the study specific files (and any additional files such as graphic files) must be uploaded to a web server. Lighthouse Studio can automatically upload your survey files if you provide it with the server information, or it can package up the survey for manual uploading using your own FTP software.

Lighthouse Studio supports both UNIX and Microsoft IIS web servers. You can host your web survey on your own web server or you can use a 3rd party web hosting service provider. Sawtooth Software also provides web hosting for Lighthouse Studio surveys.

Lighthouse Studio uses a computer programming language called Perl to run your surveys up on the web server. Most web servers already have Perl installed. You must have permission to run Perl scripts and to read, write, and delete files on your web server.

In addition to uploading your study specific files you must also upload Lighthouse Studio's Perl Scripts. These files enable all of your studies to run on the web server. It is important that you upload these files to the web server in "Binary Mode". You can find these files in Program Files\Sawtooth Software\Lighthouse Studio\Server.

3. Respondents Access Survey

Your respondents need to know how to get to your web survey. Your survey can be accessed by your users clicking on an E-mail link or by typing in a web address (URL) into a web browser.

You will generally want to point your respondents to your study's login.html page (this page can be renamed). An example of a web address would be:

You might want to issue your respondents User Names and Passwords and make it so they will be able to log in to your survey with one click. An example of this would be:

This method also allows you to seamlessly integrate Lighthouse Studio with a third party system. You can pass information from another system by setting up "pass-in" variables in Lighthouse Studio, for example Q1 and Q2, and then including them in the link. For example:

4. Collect Survey Results

You can manage your web survey once it goes "live" using the On-line Data Management Module. This module can be accessed by going to:

Use Study Summary to view the current status of your web survey. To retrieve respondent data records click on theDownload link. You can also download data directly in Lighthouse Studio under the Field menu.

The file STUDYNAME_data.csv should be downloaded to the directory where your study is located on your local computer. To reduce risk of lost data we suggest that you download and backup on a regular basis.

Once your data has been downloaded you can export it using Lighthouse Studio. The menu option File, Data Management will allow you to export to various file formats including Excel, CSV, and SPSS.

Data from a conjoint analysis or MaxDiff exercise is either analyzed within Lighthouse Studio, or exported for analysis using an additional piece of software, depending on the methodology used.

Demonstrate CBC Using Only Basic Math

This survey will illustrate how Choice-Based Conjoint surveys work. It involves choosing food for dinner at a baseball game. You will take a quick 9-question CBC questionnaire, and then, using simple addition arithmetic, we will analyze your results and place the results into a "what-if" market simulator to see how your results stack up against others who have completed this survey.
