I am just about ready to start my pilot study in my PhD research, and now is the time to select an online survey tool. There will be a variety of question types including short answers. While the study is primarily qualitative, some questions/answers will be quantitative. The survey will be conducted in August, but I will return to it for the main study within one year. It does not have to be free, but free or low cost is preferred. For example, a tool at $50 or more per month is too much, while $10 monthly is more appealing.
Your suggestions would be appreciated, along with a little rationale for the recommendation. Thanks.
