What is wrong with the response categories for the following question: "How often to you attend live music concerts: never, 1-2 times per week, 2-5 times per week, or 5 or more times per week?"

There is no option available for those who never attend live music questions. When you make a multiple choice question you need to be sure that all possible answers are covered in the options. In this case, you can easily fix this issue by adding the option 'almost never/0 ' so that this option is also covered. But in general, for more complex questions, the option 'other' is a good way to fix it.

There may be more that 1 correct answer for one case. What if you always attend 2 times per weak to a concert? Then the answer might be either 1-2 times or 2-5 times. You can work with overlapping cattegories (specifying that you have to mark all correct answers), but in practice it is better to make sure that only 1 answer can be correct (or there is 1 'most likely' option for more abstract questions, meaning that one option is more accurate than the others).

step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
