General

Do I have to register ?
Registration is optional. All visitors (registered or not) are welcome to respond to the public questionnaires and read the public boards. Registered members may submit their own questionnaires, send and receive private messages to each other, and may also submit comments on the public boards. Please note that some questionnaires are open only to members (subject to the publisher's decision).

Technical

Why do I get an error that my browser is not compatible ?
Our site makes use of advanced web technologies such as AJAX and XML transformations. These technologies are supported by modern browsers. The site was tested to be fully supported on the following browsers: Please make sure that your browser is configured to enable Javascript and cookies.
top
Do questionnaires remain open for responses indefinitely ?
No, all questionnaires are automatically closed after some time of inactivity or after the program terminates. Once a questionnaire is closed - the final results report is calculated. If you wish to keep your questionnaire open even if inactive, or close it even if active, or re-open a closed questionnaire, please contact us .
top
Is there any temporary result report before the questionnaire is closed ?
Yes, there is. The result reports and raw-data files are generated periodically in cycles which duration ranges from few minutes to few hours (depends on the questionnaire length, and the amount of new responses since last report was produced). The reports indicate the number of observations used for calculation. That number may be slightly lower than the actual number of responders so far. Once the questionnaire is closed a final report is produced. Final reports are based on all responses.
top
The questionnaire is closed already, but final results does not exist yet, why?
The result reports are generated periodically (not immediately after each response). If the questionnaire is already closed it is currently queued for calculation. Please check again within few hours (usually a few minutes will do).
top
Why do I get an error message saying that my questionnaire is archived or does not exist ?
The questionnaires are kept for a few months after they are closed. After that time they are archived/backed up and cannot be accessed online. We may consider restoring an archived questionnaire upon request from its publisher.
top
Are there any limitations for the questionnaire length ?
Actually there are, though most users are not likely to reach them in common usage. The limitations are for the amount of questions, the amount of items/choices per question, overall amount of items/choices throughout the whole questionnaire and length of the questions/items text. Users that for some reason wish to bypass these limitations please contact us and we shall consider more permissive length constraints specifically for their questionnaire.
top
How many questionnaires can I publish ?
Each user may have up to 3 open questionnaires at a time. More questionnaires can be posted only once one of the previous questionnaires is concluded, so no more than 3 questionnaires of the same user are active concurrently.
top
Can I order a custom-made questionnaires ?
If you have special requirements that our system currently does not support (for example, a certain question type or structure) you may contact us and describe what you need. We will estimate the technical implications and send you a quotation and further information. If you have an example of the desired questionnaire in a file (such as DOC or PDF) please send it as well - it will help us to estimate the project more accurately.
top
I have a document file or a hard copy of an existing questionnaire - can you type it in for me into the system ?
Please send it to us and we will give you a quotation. If the questionnaire is in a hard copy please scan it first to a JPG or TIFF file.

Privacy

Is the privacy of the responders kept ?

Definitely. Our system does not publish any uniquely identifying information (such as IP addresses) or attach any such information to the responses, so no one can relate the responses to the responder identity, including the publisher of the questionnaire. Yet, responders should be cautious with any uniquely identifying information they voluntarily provide.

If the publisher sends a private invitations to a potential responders' mailbox, the publisher may know who are the responders that accepted the invitations in a dedicated list (separated from the results report) but the email addresses are not attached to the responses, and the results report is based only on answers explicitly given in the questionnaire form.

top
How can I be extra cautious to make sure that my privacy will not be violated ?
Please note that sometime an individual may be identified by his/her specific answers. For example, suppose the HR department conducts an employee satisfaction survey, and one of the questions is age related, and there is only a single employee in the organization at a certain age. His/her answers can be identified by those who are aware to this information. Participants should be cautious with any uniquely identifying information they voluntarily provide.
top
Is there an option to conduct a survey where the results will be kept visible only to the publisher ?
We allow to keep the results report hidden until the questionnaire is closed. The publisher may make sure that the responders are not biased by the existing report. Once the questionnaire is closed and final results are calculated they become available to all users. Premium questionnaire's reports may be kept hidden even once the questionnaire is closed.

Statistics

Which statistics are supported ?
We currently support: Simple distributions, Crosstabulations, Mean, Median, Standard-deviation, Kurtosis, Skewness, Chi-square, T-Test, Anova, Spearman's correlations, Pearson's correlations and more.
top
I'm not a statistician, I don't understand parts of the report
Don't worry, you are not alone. Most users don't understand it all. The report may appear in a "standard" mode or in an "advanced" mode. For most business regular needs the "standard" report is enough. The "advanced" report is for academic usage and contains data that is not relevant to most users.
top
How do you choose which statistics to calculate ?
The statistics are calculated based on the question type (ie, nominal, ordinal, interval). Please note that the statistics are calculated automatically without understanding the meaning of the questions, so not all calculated statistics are relevant in all cases.
top
Does the results report makes the usage of statistical software redundant ?
That depends on your research purpose and hypothesis. The results report includes many statistics, yet it may lack specific calculations needed for your research. In such a case you may download the raw data for further analysis using your favorite software.
top
Can I have access to the raw data for further analysis ?
Once the questionnaire is closed and final results are calculated, raw data is also available in a CSV format. If the file contains non-English characters it is encoded using UTF-8 . The CSV format can be used with common softwares
  • Statistical software: SPSS, SAS m.i. , STATISTICA, EViews m.i. etc.
  • Spreadsheet software: MS-Excel m.i. , OpenOffice m.i. etc.
  • Mathematical software: MATLAB, Octave m.i. etc.
