A major disadvantage of primary data collection is:

a) it requires more sophisticated training and experience to design the study and collect data.

b) it cannot be tailored to meet specific research needs.

c) it is too general to meet researcher's and manager's needs.

d) it can be accessed only through syndicated databases or unstructured data mines.

e) it does not offer behavioral insights that can be obtained from secondary data.

b) it cannot be tailored to meet specific research needs.

Explanation:

Primary data collection is defined as the data collected from source or from first hand materials. It involves processes like survey, interviews or experiments.

Data is collected for research purposes.

On the other hand secondary data collection is the process by which data is collected from analysis of Pratt data. It shows conclusions and relevant information to meet a specific need.

A disadvantage of primary data collection is that it can't be used to meet a specific need. Secondary information will have to be obtained first.
