Sources Of Data
Original Source Data
Collected the data yourself
Questionnaires, face to face interiews and observation.
Get the exact data you need, exact amount of data you need.
Long time to collect, can be expensive to collect.
Indirect Data
Data collected for one reason but then used for another.
Weather data and online shops.
May be cheaper and less time consuming to obtain than original source data.
May not know where the data comes from so it is less reliable, may not be able to obtain the exact data you need.
Archived Data
Data that is not immediately available online. It has been copied then removed from the system and stored safely online.
Parish birth/death records and famous person archive.
Even though data is not being used there is still a permanent copy of it.
Takes time to locate.
