Survey bias can significantly impact the accuracy of product growth decisions. There are five main types of survey bias: question bias, response bias, sampling bias, data collection and analysis bias. To minimize these biases, it is crucial to build diverse internal teams to support the process. In-app surveys like Microsurveys can help collect user feedback directly within a product, increasing their completion rate. Staying objective while running product surveys involves setting up checklists and QA stages in the survey creation process to identify potential biases.
