It has been pointed out here that secondary data can be collected from organisation sources or from secondary sources generally the originating sources of external secondary data should be preferred because of the several reasons. First, the originating source is more likely to explain the objects and procedure of data collection. Secondly, the originating source is more likely to present all the data, where as a secondary source may present a part of such data convenience. Finally, the originating source would be more accurate since each additional repeating source of day secondary data present another possible source of error.
