Why people fill out surveys

Why People Fill Out Surveys

  • Social Exchange Theory

    Theory of human behavior in which actions of individuals are motivated by the return these actions are expected to bring.

    Elements of reward, cost and trust

Social exchange theory

Social Exchange Theory

  • Rewards

    show positive regard

    say thank you

    ask for advice

    support group values

    give tangible rewards

    make the questionnaire interesting

Social exchange theory1

Social Exchange Theory

  • Reduce Social Costs

    avoid subordinating language

    avoid inconvenience

    avoid embarrassment

    make it short and easy

    minimize requests for personal information

    keep requests consistent

Social exchange theory2

Social Exchange Theory

  • Establish Trust

    provide token of appreciation in advance

    sponsorship by legitimate authority

    make task appear important

    invoke other exchange

Constructs and measurement

Constructs and Measurement

  • What do you want to know?

  • What are the variables?

  • How will you measure it?

    behavior, attitudes, feelings, demographics

Survey error

Survey Error

  • Sampling Error – Who are you sampling?

  • Coverage Error – Does your list include everyone?

  • Measurement Error – Does everyone answer a question the same way?

  • Non-response Error – Why did respondent not answer:

    Instrument (whole questionnaire not returned)

    Item (question not answered)

Non response error

Non Response Error

  • Only an issue if non responders would answer differently and change results

    compare early to late respondents

    double dip

Random sampling

Random Sampling

  • How much sampling error can you tolerate?

  • How large is the population?

  • How varied is the population?

  • How confident do you wish to be about estimates made from the sample?

Random sampling chart

Random Sampling - Chart

Pop Size 50/50 split 80/20 split

  • 80 71

  • 132 111

  • 196 153

  • 234 175

  • 260 188

    1000 278 198

Sample size for a 95% confidence level

And a + 5% sampling error

Random sampling1

Random Sampling


    A www site that will generate random numbers which you can use for random selection of participants on a mailing list.

Writing questions

Writing Questions

  • Everyone will interpret the same way

  • Respondents are able to respond accurately

  • Respondents are willing to answer

Writing questions1

Writing Questions

  • Use simple words

  • Keep it short

  • Be specific

  • Do not talk down

  • Avoid bias

  • Avoid hypothetical questions

  • Use complete sentences

Question criteria

Question Criteria

  • Does the question require an answer?

    If you fixed dinner last night, did you eat meat as part of that meal?

  • To what extent does the respondent have a ready made and accurate answer?

    Are tall people more likely to be elected President?

  • Can respondent accurately recall and report past behavior?

    How much television did you watch last month?

Question principles

Question Principles

  • Use simple words and phrases




    most important……………… priority

    free time……………………….leisure


    your answers………………….your responses to this


Question principles1

Question Principles

  • Avoid vague quantifiers

    How often did you attend religious services last year?

     Never

     Rarely

     Occasionally

     Regularly

Question principles2

Question Principles

How often did you attend religious services during the past year?

 Not at all

 A few times

 About once a month

 Two or three times a month

 About once a week

 More than once a week

Question principles3

Question Principles

  • Avoid bias by using both positive and negative sides in the question stem

    “To what extent do you agree….”


    “To what extent do you agree or disagree with this statement…. “

Question principles4

Question Principles

  • Avoid double-barreled questions

    16. Should the new school have a swimming pool that includes lanes for swimming laps and is not enclosed for winter use?

Question principles5

Question Principles

  • Avoid asking respondent to say yes in order to mean no.

    5. Do you favor or oppose not allowing the state to approve a casino without approval from 60% of the voters?

     Favor

     Oppose

Survey design and implementation

5. Do you favor or oppose requiring 60% approval by voters in order for a casino to be built.

 Favor requiring 60% approval

 Oppose requiring 60% approval

Question principles6

Question Principles

  • Use equal numbers of positive and negative categories for scalar questions AND distinguish undecided from neutral by placing at the end of the scale.

Survey design and implementation

To what extent do you agree or disagree with this statement: “Listening to classical music is good for a persons emotional health.”

 Strongly agree

 Somewhat agree

 Neither agree nor disagree

 Somewhat disagree

 Strongly disagree

 No opinion

Question principles7

Question Principles

  • Soften impact of potentially objectionable questions:

    Have you ever shoplifted something from a store?


    Have you ever taken something from a store without paying for it?

Survey design and implementation

22. What was your total income from all sources in 2003?

______________ Total income for 2003

22. Which category best describes your total income from all sources in 2003?

 $10,000. or less

 $10,001. to $20,000.

 $20,001. to $35,000.

 $35,001. to $50,000.

 $50,001. or above

Question principles8

Question Principles

  • Don’t combine numbers and words

    Doing so may impact respondents perception of the scale.

    1= strongly agree, 2 = agree,

    3 = disagree, 4 = strongly disagree

Question principles9

Question Principles

  • Eliminate check-all-that-apply questions to reduce primacy and sufficiency effect.

    People tend to check the first ones more than the last ones and sometimes check a few and feel that is enough to satisfy the researcher.

Order of questions

Order of Questions

  • A questionnaire is like a conversation. It evolves according to social norms. Constantly switching topics makes it appear as though the researcher is not listening to the respondents answers.

  • Keep completed questionnaires in secure location

Mixed mode surveys

Mixed Mode Surveys

Responses differ by mode:

“Excellent Health” = 44% by personal interview

= 37% by telephone

= 30% by mail

social desirability


primacy vs recency effect

Telephone surveys

Telephone Surveys

  • Difficult to obtain phone numbers

  • Caller id and answering machines may screen calls

  • Need well trained interviewers

  • Limited number of questions and answers

Internet surveys

Internet Surveys

  • Consider coverage error. Does your entire audience have and use the internet on a regular basis?

  • E-mail addresses change often

  • Difficult to include incentive

  • Shorter less detailed questionnaire

    Survey Monkey

Research ethics

Research Ethics

Anonymous – No way to know who returned the survey

Confidential – Only researcher can connect the respondent with their answers. All answers remain confidential.

Research ethics1

Research Ethics

  • If you wish to publish results you MUST get approval from UCRIHS before you send out surveys.
