Resumen del Recurso
Direct & Indirect Data
Direct
The source and collection method is know and verified
The exact data required can be collected
Can change the data being collected in response to answers
You only gather as much or as little as you need
You may be able to sell the data for other purposes.
May not get a large range of data
Data may not be available-location/time
Data gathering may take a long time to collect.
It may involve having to purchase equipment such as data loggers and computers.
Indirect
Large range of data available that could not have been collected directly
Data can be available from different locations and time periods
Analysis might already have been complete on some of the data
Takes less time to gather than original (direct) data.
It may be cheaper to obtain than gathering original data
Archiving ensures that all the data you have collected is available for uses you have not considered just yet.
Do not know if any bias was placed on the collection
Cannot be certain of accuracy of the recording of data
May not have all the information about how, when and where it was collected to make a valued opinion on its usefulness
If the information was not originally collected, may not be able to get hold of it
If you have to buy the data from a specialist company then it may be more expensive that collecting it yourself.
There may be only a small part of the data needed so you have to extract what you want from a large data set.
