Creating Significant Figures Questions
This guide is about creating Significant Figures questions in your quizzes, surveys or in your Question Library. For more information, please see Creating Questions in the Question Library, Creating a Quiz and Creating a Survey.
Significant figures questions require respondents to answer in scientific notation and provide solutions that contain a specified number of significant figures. Math and science units commonly use this question type. You can ensure each respondent receives a unique question by including set variables that randomly generate scientific notations within the problem.
