        Alternatives assume a high frequency
      2. Low frequency scale
        Alternatives assume a low frequency
      3. Graphic rating scale
        Requires a mark along a continuous line that is anchored with descriptions at each end

  2. Non probability sampling
    1. Convenience sampling
    2. Purposive sampling
      1. Obtain a sample of people that meet a predetermined criterion
    3. Quota sampling
