Marketing research uses primary and secondary data
Secondary data has many advantages, like being inexpensive and readily available
Secondary data also has limitations: potential errors and biases
Secondary data should be accurate, reliable, precise, unbiased, valid, appropriate, and timely
Potential errors in secondary data include sampling and non-sampling errors, errors invalidating data, errors needing reformulation, and errors reducing reliability
All error sources reduce the reliability and validity of results; careful treatment is needed
Secondary data is gathered by others for other purposes but can be useful in many analyses
Census publications are primary sources of secondary data
Data that has been manipulated or reorganized could be invalid
Concept errors exist when the data doesn't perfectly measure the intended concept
Using secondary data in analysis increases the chance of error
Secondary data may have issues related to sampling errors, measurement errors, errors needing reformulation, and errors impacting reliability
Sampling errors occur when the sample doesn't reflect the entire population
Non-sampling errors can include frame errors, measurement errors, sequence bias, interviewer bias, and non-response bias
Errors can invalidate data due to manipulation, contamination, inappropriateness, confusion, or carelessness
Errors reducing reliability include clerical errors, changes in collection procedures, failure to use correct data
Time lag between data collection and publication is a potential issue
Data accuracy, timeliness, and reliability are important considerations for using secondary data in analysis
