Why do people answer questions?

A dollar bill with a mail survey works
better than $10 (guaranteed) later

Response relies on
effort, reward, and trust
People will only respond if they trust
you. After that, it's a balance between
the perceived reward from filling in the
survey compared to the perceived
effort that's required. Strangely
enough, if a reward seems 'too good to
be true' that can also reduce the
response.

The aim of a survey is to get a number
that helps you to make a decision
Caroline Jarrett @cjforms (CC) BY SA-4.0
8
To get better results from your survey,
think about the Survey Octopus
Caroline Jarrett @cjforms (CC) BY SA-4.0
People ask me about surveys
• “How many people do I need to ask?”
• “How many questions can I have?”
• “Please tell me whether this is a good question”
• “I think it’s best to have 5 points in my rating scale, but
my boss wants to have 7. Who is right?”
9
Agenda “How many people do I need to ask?”
“How many questions can I have?”
“What makes a good question?”
“How many points in a rating scale?”
10
Caroline Jarrett @cjforms (CC) BY SA-4.0
Caroline Jarrett @cjforms (CC) BY SA-4.0
To find out how many people to ask,
start at how many we need to answer
Caroline Jarrett @cjforms (CC) BY SA-4.0
Fieldwork:
Who answers?
11
Caroline Jarrett @cjforms (CC) BY SA-4.0
Whether they’ll answer depends
on effort
Questions:
What are you
asking about?
How many
questions?
12
Caroline Jarrett @cjforms (CC) BY SA-4.0
Caroline Jarrett @cjforms (CC) BY SA-4.0
And on the reward you’re offering
Goals:
Why are you asking?
Is helping you a reward in itself?
Are you offering any other
incentive?
13
Caroline Jarrett @cjforms (CC) BY SA-4.0
Then there’s the
‘Justin Bieber North Korea’ problem

We don’t just want answers,
we want answers from the right people

we get our sample from

the list you
sample from

And now it’s easy to work out
how many to ask
Caroline Jarrett @cjforms (CC) BY SA-4.0

people to ask

“You're using this site from outside the
UK. Where are you answering from?
We’d like answers like these
– Anchorage Alaska U.S.A.
– Cameroon
– Dubai, United Arab Emirates
Even better, extra-interesting answers like these:
– Cote d'Ivoire / France / UK.
– Canada, originally from the UK
– Philippines, would like to work in UK with my husband if possible
But definitely not like these:
– ä¸å›½
– its not important
– nnnnnn
– none of your business 20

Insights are the numbers
that you use for decisions

“How many questions can I have?”
Let’s work backwards from insights
25
Which answers do you need to make the decisions?
Caroline Jarrett @cjforms (CC) BY SA-4.0
You need accurate answers
to the questions
26
Will your respondents give you
good answers to all of them?
27
In your last five days at work, what
percentage of your work time do you
estimate that you spent using publicly-
available online services (not including
email, instant messaging, and search) to
do your work using a work computer or
other device?

You need questions that your
respondents can answer accurately
Which
questions
will get you
the answers
that you
can use?
30
Caroline Jarrett @cjforms (CC) BY SA-4.0
Now we get to fieldwork
31
How many
of those
questions
are people
willing to
answer?
Caroline Jarrett @cjforms (CC) BY SA-4.0
Fieldwork used to be expensive
so a survey was a rare event.

1950s mindset: “Ask Everything”
33
Survey =
Big Honkin’ Survey
Caroline Jarrett @cjforms (CC) BY SA-4.0
2015 mindset: the Light Touch survey
• Choose ONE question
• Find ONE person
• Ask the question, face-to-face
• See if you can make ONE decision
• Improve, iterate, increase
34
Tip Interview first
Caroline Jarrett @cjforms (CC) BY SA-4.0
35
Time for new question
Caroline Jarrett @cjforms (CC) BY SA-4.0
36
One way to
iterate,
improve,
increase
Big Honkin’ Survey
• Negotiate to get survey
down to 20 questions
• Ask 10,000 people
• Get 1,000 responses
• Take a week (or more) to
analyze the responses
• Have a big presentation
a month later
Light touch survey
• ‘Question of the day’
(one question)
• Ask 100 people
• Get 50 responses
• Analyze them same day
• Present same day
• Repeat 4 x 5 = 20 times
37
Caroline Jarrett @cjforms (CC) BY SA-4.0
Caroline Jarrett @cjforms (CC) BY SA-4.0
Do both!
Big Honkin’ Survey
• Big numbers are
impressive
• Can compare answers
from different segments
• Easier ‘sell’ to
stakeholders
Light touch survey
• Quick, useful results
• Rapidly get better
at doing surveys
• Wonderful way to test the
questions for the Big
Honkin’ Survey
38
Agenda “How many people do I need to ask?”
“How many questions can I have?”

Tip
Don’t stress too much about
the number of points in your
rating scale

Well, OK, stress a little bit.

downright

  • 37. Big Honkin’ Survey • Negotiate to get survey down to 20 questions • Ask 10,000 people • Get 1,000 responses • Take a week (or more) to analyze the responses • Have a big presentation a month later Light touch survey • ‘Question of the day’ (one question) • Ask 100 people • Get 50 responses • Analyze them same day • Present same day • Repeat 4 x 5 = 20 times 37 Caroline Jarrett @cjforms (CC) BY SA-4.0
  • 38. Caroline Jarrett @cjforms (CC) BY SA-4.0 Do both! Big Honkin’ Survey • Big numbers are impressive • Can compare answers from different segments • Easier ‘sell’ to stakeholders Light touch survey • Quick, useful results • Rapidly get better at doing surveys • Wonderful way to test the questions for the Big Honkin’ Survey 38

  • 43. Caroline Jarrett @cjforms (CC) BY SA-4.0 Response relies on effort, reward, and trust People will only respond if they trust you. After that, it's a balance between the perceived reward from filling in the survey compared to the perceived effort that's required. Strangely enough, if a reward seems 'too good to be true' that can also reduce the response.

Editor's Notes

  • #6: People will only respond if they trust you. After that, it's a balance between the perceived reward from filling in the survey compared to the perceived effort that's required. Strangely enough, if a reward seems 'too good to be true' that can also reduce the response.
  • #7: This is a genuine invitation from local government, but the layout and images in the invitation make it look as if it's an approach from some sort of spammer or scammer.
  • #8: The survey sits between 'what you want to ask', 'who you want to ask' and 'the number'
  • #12: The survey octopus has 8 tentacles. We'll visit each one in the next few slides. We’ll get our survey to the people who will answer in what the survey methodologists call ‘fieldwork’ – that might be a pop-up a website, a mail survey, or face-to-face interviews.
  • #13: The octopus again. This time we're looking at 'the questions we ask'.
  • #14: The resources you have will help you to decide on the reward you’re offering
  • #15: Prank leaves Justin Bieber facing tour of North Korea By Daniel Emery Technology reporter, BBC News 5 July 2010 Image caption It is highly unlikely Bieber would be given permission to enter North Korea Canadian singer Justin Bieber's has become the target of a viral campaign to send him to North Korea. A website polled users as to which country he should tour next, with no restrictions on the nations that could be voted on. There are now almost half a million votes to send the singer to the secretive communist nation. The contest, which ends at 0600 on 7 July, saw North Korea move from 24th to 1st place in less than two days. Many of the votes are thought to originate from imageboard website 4chan, which has built a reputation for triggering online viral campaigns.
  • #16: The octopus, with focus on "the ones whose answers you use"
  • #17: The octopus, with focus on 'The list you sample from'
  • #19: The octopus again; we've looked at 6 of the 8 tentacles.
  • #20: The octopus, looking at two tentacles that are about response: 'The ones whose answers you can use’, and ‘the answers that you get’
  • #22: We're looking at the last tentacle of the octopus, this time 'The answers that you use'
  • #23: The 8 tentacles of the Survey Octopus are: Left side: Goals: the resources you have Questions: the questions you ask Response: the answers you get Insights: the answers you use Right side: The list you sample from The sample you ask The ones who answer The ones whose answers you use
  • #29: Two questions from a survey: '24: Do you use a Windows or Mac computer'? '25. What is your gender'?
  • #30: Photo of a Samsung (android) mobile with the same questions as previous slide. If you only have an Android mobile, how do you answer ‘do you use a Windows or Mac computer’ when the answer options are ‘Windows’, ‘Mac’ and ‘Both’?
  • #37: A process starting with one person face to face, continues through 10 people by phone, gets to 100 people by email or pop-up. It’s best to check that your question works with one person before you hassle 10 people with it. Then check it works with 10 people before you send it to 100. Once you’ve tried it on 100 people, you might be more interested in a new question than getting more answers on this question
  • #41: Photo of a Samsung (android) mobile with the same questions as previous slide. There aren’t any options for ‘other’, but some people don’t use a Windows or a Mac. Most people identify as ‘Male’ or ‘Female’ but some people don’t.
  • #42: A model wears a t-shirt with Gender: 'Male' (crossed out), 'Female' (crossed out) and 'Other' (added and ticked'.
  • #44: People will only respond if they trust you. After that, it's a balance between the perceived reward from filling in the survey compared to the perceived effort that's required. Strangely enough, if a reward seems 'too good to be true' that can also reduce the response.
  • #45: Obvious questions require no effort to answer. Interesting questions are rewarding to answer. Appropriate questions are ones that inspire trust in the respondent.
  • #46: People come to the web with their own questions, so they’re likely to know why they are on your website. It’s a relatively interesting question to answer, and it’s appropriate to ask visitors why they’re visiting.
  • #56: This is a more conventional way of looking at the octopus tentacles
  • #57: If we just look at the issues (no tentacles) we get this slide
  • #58: This slide translates the issues into the technical terms used by survey methodologists
