I design surveys as part of my job and this is a howler. You could interpret what if any results you'll get from this in any way you like. Maybe that's the point.
Q1. Do you play any sports? *
Yes
No
Due to 'play' it's not clear if running counts or not
Q2. Do you want to be faster in running? *
Yes
No
Maybe
As there's no 'I don't run' option you're assuming the respondent is a runner, but if they say no at Q1 what do they say here? What if they play football/tennis/golf but don't run at all?
Q3. Do you run for training, competition, or to stay fit? *
Yes
No
Is this question asking which of those 3 things the respondent runs for? I.e. to separate out competiive vs. fun runners? A yes/no response obviously doesn't do that.
Or is it asking if they run for any of those reasons? If so, wouldn't 100% of runners say 'yes'? What other reasons for running are there?
Or is this question identifying runners vs. non-runners so you can discard non-runners' responses to the rest of the survey? If so, you should tell them to stop the survey here, not carry on. And the question should simply ask if they run or not.
Q4. How often do you run?
More than 4 times in a week
Once or twice a week.
One or twice a month
Couple of times a year
Never
What does someone answer if they run 3 or 4 times a week? There isn't an option for those people, yet that's probably the most common frequency of all.
No-one runs a couple of times a year or once a month. Less often than once/twice a week would do as the minimum.
By including 'never' you seem to have asked 3 times already whether the person runs or not. What will you do with people who answer Q1=no, Q3=yes, Q4=no or some other nonsensical combination?
Q5. If you run, do you time yourself to increase your stamina and/or stay on pace of a target goal? *
Yes
No
I don't run.
I time myself for other reasons.
You're asking 2 questions in one which always fails. Ask if they time themsevles then ask what for (if you need to). And how does timing increase your stamina? Are you sure you're a runner?
"If you run..." "I don't run". Am I spending longer writng this than you did the original survey? I thought engineers had natural attention to detail.
Q10. How much would you pay to have a timer to time you by itself as you run? *
$45
1
2
3
4
5
6
7
8
9
10
$110
What if they say no I don't want a timer like that, which wouldn't work anyway? What if they want to spend under 45 or over 110? What if they don't run? What if they don't time themselves?
