        Dealing with Field Work
        • There are two main types of errors in survey 
           research:
            • Sampling error
            • Non-sampling error
        • Non-sampling error includes all errors in a survey 
           except those due to the sampling plan or sample 
           size.

        Data Collection
        • Data collection is the phase of the marketing research 
           process during which respondents provide their answers 
           or information to inquiries posed to them by the 
           researcher.
