    • About this presentation
      Sampling
      How to target your respondents
      Survey methods
    • Sample
      A subset of individuals within a population of interest
      Sampling is the act, process, or technique of selecting a suitable sample, or a representative part of a population for the purpose of determining parameters or characteristics of the whole population
      Goal of sampling: to be able to make inferences to the population in question
    • Why sample?
      Lower cost
      Faster data collection
    • Sampling process
      Defining the population of concern
      Specifying a sampling frame, a set of items or events possible to measure
      Specifying a sampling method for selecting items or events from the frame
      Determining the sample size
      Implementing the sampling plan
      Sampling and data collecting
      Reviewing the sampling process
    • Define the population
      Definition: Entire universe of individuals who have characteristic of interest
      Examples: Residents of city, residents of county, library card holders, users, nonusers, visitors to library, computer lab users, program attendees
    • Sampling frame
      Definition: has a property that we can identify and can include in our sample
      Examples: telephone directory, city directory, patron database, attendance sheets, voter registration list, utility bill recipients, newspaper readers, random digit dialing (RDD)
    • Sampling methods
      Probability sampling: every individual has an equal chance of being selected
      Nonprobability sampling: some units in the population have no chance of selection or the probability of selection can’t be accurately determined
    • Sampling methods examples
      Probability
      Simple random
      Systematic
      Stratified
      Nonprobability
      Convenience
      Judgment
      Quota
      Snowball
    • Sampling example #1
      Simple random
      Population: Patrons
      Frame: Patron database
      Method: Random number generator—in Excel: =RANDBETWEEN(num1,num2)
    • Sampling example #2
      Systematic
      Population: City residents that have a listed land-line telephone
      Frame: Telephone directory
      Method: Randomly select a number n (ex., 20) or smaller, start there on the first page of the directory and select every nth (ex., 20th) entry
    • Sampling example #3
      Convenience
      Population: Library visitors
      Frame: Anyone who approaches or passes by the reference desk
      Method: Stop as many people as possible
    • Population example
      Entire universe
      Population: Event attendees
      Distribute questionnaire to everyone in attendance
    • Sample size criteria
      Level of precision/sampling error (e.g., ±5 percent): range in which the true value of the population is estimated to be
      Confidence level: repeat sample values are normally distributed about the true value
      Degree of variability: heterogeneous populations require a larger sample size
    • Determine sample size
      (Obtained responses)
    • Implement the sampling plan
    • Evaluate the sample
      Response rate
      Number completed
      Total number in sample
