Descriptive Statistics (Lesson 6/6)

Data Collection

1 / 3

Designing Surveys

If you've taken a survey before, you know that they can be very poorly designed. We've compiled below some examples of terrible survey questions:

Question
Why it's terrible

How much do you love Perplex?

Biased question, people don't like to be too critical

How often do your parents argue about money at home?

Too personal

Tell me about your mental health.

Unstructured! I don't know what you're asking

How many hours do you study each week?

  • Never

  • 3

  • Quite a lot

  • Yes

Inconsistent answer choices
