Is 30 questions too much for a survey?

Yes, 30 questions can be too much for a general survey, leading to respondent fatigue and lower completion rates, but it can be acceptable for in-depth studies (like employee or market research) if the audience is motivated and the survey is well-designed, focusing on essential questions and using mostly closed-ended formats to keep it concise (around 10-15 mins). Shorter is usually better, with 10-20 questions often optimal for general use, but context matters.

Why 30 samples for normal distribution?
