You create a survey in order to get information about a product or a campaign, so you wish to see the results of your survey, try to draw conclusions, and come to decisions.
The Result Management and Charts and Analysis module of WinSurvey help you to analyze your results, but for significant results and data, it is important to get as many responses as possible (at least 30).
The more complete the questionnaires are, the more realistic the statistics will be. If a respondent completes only one question from a survey, that survey cannot be considered as a valid survey.
To help you validate the surveys WinSurvey provides some validation functions that are used before the respondent submits the survey.
The statistic values, like mean, median or standard deviation, help you to draw a conclusion about your survey. You do not have to hire a mathematician to calculate these statistics, because WinSurvey will help you.
