Don’ts!Don’ts!Don’t ask a question if you already know

the answer!Don’t ask a question if you’re not prepared

to do anything about the answer!Don’t ask “nice to know” questions. Ask questions only if you know what

you will do with the answers.

What do you really want to What do you really want to know?know?

Take three minutes and write down four or five things you would really like to know from a questionnaire you are designing.

Self-reportsOne-point-in-timeAlthough they may measure perceptions

and intentions, they won’t measure behavior change

Designing QuestionnairesDesigning Questionnaires

Keep it short and on point. Use questions that have been used and tested by

others if possible Be sure questions have “face validity”. Include important demographic questions. Make sure ALL questions are germane to the

evaluation. Pre-test all questionnaires on same population.

Yes or NoYes or No

SimpleUse with information that has no middle

ground– Do you own your own home?– Are you a U.S. citizen?

Page 13: Effective Surveys

One-best answerOne-best answer

Provide only one of many possible answers

“Of the following, which topic would you MOST like to receive information about?”

a. Pasture Management

b. Farm Estate Transfer

c. Dairy Cattle Nutrition

More about questionsMore about questions

Avoid double barreled questions– “Did you find the workshop helpful and

interesting?”

Don’t use leading questions. – “Do you agree that funding for Extension

should increase?” yes or no

Don’t use abbreviations and jargon

Page 20: Effective Surveys

Questions… continuedQuestions… continued

Use ranges for choices instead of precise numbers. Put choices in logical order.

Be very clear– “How many times did your club meet last

year?”

Avoid questions that are too demanding.– “Rank the following 15 items in order of

importance to you.”

Page 21: Effective Surveys

Yet more on questions…Yet more on questions…

Avoid making assumptions.– “How many children do you have?”

Avoid bias. – “How would you rate the workshop? a.

excellent; b. good; c. satisfactory”Make response categories clear.

– “How many acres do you own?” 0-10, 10-20, 20-50, 50-100

Page 22: Effective Surveys

Question OrderQuestion Order

Question order does influence results. Begin a questionnaire with something that isn’t

too difficult to answer, but will be of interest to the participant.

Put easiest (demographic information) at the end – this is where people sometimes lose interest and if the questions at the end are less demanding, they are more likely to finish.

Page 23: Effective Surveys

Pre/post TestsPre/post Tests

Use an identical knowledge test, before the educational program and then after.

Might ask specific questions about a subject, like, “How many servings of fruits are recommended for an adult every day by the new food pyramid?”

Might ask them to rate their knowledge of something, “Please rank your understanding of the new food pyramid recommendations.”

Page 24: Effective Surveys

Pre/post test considerationsPre/post test considerations

Need to pair the tests (make sure you match up pre and post responses for each individual – not average scores) if you want to report on individual knowledge gained. – Use name, id number, birthday, etc.

Internal validity might be affected – testing influences.

Page 25: Effective Surveys

Retrospective SurveyRetrospective Survey

Sometimes called a post-then-pre designBetter way to measure self-reported

behavior changesAvoids the issue of a participant not

knowing what they don’t know.– “Do you eat the appropriate number of fruits

and vegetables daily?”

Page 26: Effective Surveys

Example retrospective questionExample retrospective question

After today, will you

Often Sometimes Never

Before today, did you

Often Sometimes Never

Check equipment calibration?

Use protective gloves?

Scout fields for specific pest problems?

Types of ErrorTypes of Error

Don’t get hung up on sampling error. (But be sure to have enough cases for statistical power.)

Non-sampling error is more critical.– Non-response– Question wording effects
