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.

Why do people answer questions?
7Caroline Jarrett @cjforms (CC) BY SA-4.0
People ask me about surveys
“Please have a look at this survey”
“How many people do I need in my sample?”
“Tell me whether this is a good question”
“I prefer 5 points in a rating scale, but my boss likes 7.
Who’s is right?”

What number do

The survey is a systematic method
for gathering information from
(a sample of) entities for the purpose of
constructing quantitative descriptors of
the attributes of the larger population of
which the entities are members.

The aim of a survey is to get a number
that helps you to make a decision

“Yes, to make <decision> we need <number>”

Goals and resources:
Why are you asking?
Is helping you a reward in itself?

almost any number of points

Editor's Notes

  • #5 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.
  • #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.
  • #13 The survey sits between 'what you want to ask', 'who you want to ask' and 'the number'
  • #19 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.
  • #20 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.
  • #21 The octopus again. This time we're looking at 'the questions we ask'.
  • #22 The resources you have will help you to decide on the reward you’re offering
  • #23 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.
  • #25 The octopus, with focus on 'The list you sample from'
  • #27 The octopus again; we've looked at 6 of the 8 tentacles.
  • #34 The octopus again; we've looked at 6 of the 8 tentacles.
  • #36 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.
  • #37 Obvious questions require no effort to answer. Interesting questions are rewarding to answer. Appropriate questions are ones that inspire trust in the respondent.
  • #38 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.
