Document Summary

Firms also can purchase more specific or applicable secondary data from specialized research firms through paying a fee (syndicated data). Finally, secondary sources can be accessed through internal sources: ex. Should pass the crap test (currency, reliable, authority, purpose) or could make wrong or misleading inferences or conclusion: secondary data are acquired for other purpose so may not be completely relevant, accurate, nor trustworthy. Primary data collection can help eliminate some of the problems inherent to secondary data. A major advantage of primary research is that it can be tailored to fit the research questions, more reliable and validity: disadvantage. Usually more costly and timely to collect primary than secondary, often require extensive training and experience to design and collect primary data that are unbiased, valid, and reliable. Reliable (same result is achieved when a study is repeated under identical situations) Valid (that it measures what it is supposed to measure)
