USA Street Survey Very Funny

A survey is one method researchers may use to collect information relative to their study.

Surveys describe the

  • opinions
  • behaviors
  • characteristics
of a population of interest.

Types of Surveys

Creating the Research Instrument

  • Maximize information
  • Minimize burden on participants
  • Pattern after previously successful questionnaires/interviews
  • Pilot test the questionnaire or interview

Questionnaire Basics

Guidelines for Quality Questionnaire Creation

be simple & clear

  • short questions & responses
  • ask explicit questions
  • emphasize words for clarity (NOT)
  • avoid double negatives
  • avoid two part questions
cover all possibilities ("other")
give points of reference (ranking) vs. vague questions
ask only important questions

pilot test to identify & correct weak spots


Open form vs Closed form questionnaires

  • open = no response limitations
  • closed = restricted set of possible responses

Sampling

Sampling = a systematic procedure for for choosing the group to be surveyed

Samples should reflect entire population of interest


Allows for impossibly large groups to be studied and findings to be generalized


Random Samples

cluster samples

stratified random samples

Freddy's awesome information about probability and all mathy stuff


Samples of Convenience

when it's impossible to get a true random sample of the population


Missing Data

can be a big problem in sampling

Clear as mud?
