For example, many trade magazines survey their members to derive estimates of market size, market growth rate and purchasing patterns, then average out these results. Often these statistics are merely average opinions based on less than 10% of their members.
• Data may be in a different format or units than is required by the researcher.
• The methodology used by the party for collecting the secondary data is not explained and the accuracy level may not be verified.
• Much secondary data is several years old and may not reflect the current market conditions. Trade journals and other publications often accept articles six months before appear in print. The research may have been done months or even years earlier.
