 A functioning questionnaire design does not guarantee that every participant understands the questions correctly. Therefore, the most important step to generate valid data is a pretest. A functioning questionnaire design does not guarantee that every participant understands the questions correctly.

-In order to conduct a pretest, activate the pretest mode for your project. In **Project Settings**, click on the tab Pretest and tick the box in front of //Allow pretest//, set a //Pretest password// and save the changes by clicking //OK//. +Pretests often fall short, especially in online surveys. This accounts for a large part of the perceived poor data quality of online surveys used in studies.Therefore, how to perform a proper pretest is explained below.

-Now people can access the questionnaire using the correct Pretest password. Pretests are often not used effectively in online questionnaires leading to the alleged poor data quality of online surveys. Therefore, the following steps describe briefly how to conduct an effective Pretest.+

   - Once you have incorporated all your changes, you should repeat the pretest -- otherwise you may be making matters worse. Of course you need to recruit different people, since the original testers now know how to understand your questions.   - Once you have incorporated all your changes, you should repeat the pretest -- otherwise you may be making matters worse.

   - Even good questionnaires need a couple of alterations. Usually, 2-4 Pretest rounds are needed, to turn a good questionnaire into a really good one. However, the effort is worthwhile: better data quality, less drop-outs and less effort during the analysis and interpretation. Especially under time pressure a pretest should not be missed out on.   - Even good questionnaires need a couple of alterations.
