Advantages	Disadvantages
You get the exact data you need	Data gathering may take a long time to collect.
You only gather as much or as little as you need	Data gathering may be expensive as you hire other companies to get it for you.
You know exactly where the data came from and so you can estimate how reliable it is.	It may involve having to purchase equipment such as data loggers and computers.
You may be able to sell the data for other purposes.	It may not be possible to gather original data due to the time of year e.g. you want winter snowfall data and the project is now in the middle of summer.

Describe an advantage of using primary data to gather consumers shopping habits

Advantages	Disadvantages
Takes less time to gather than original (primary) data.	You may not know exactly where the data came from and so it may be unreliable
It may be cheaper to obtain than gathering original data	If you have to buy the data from a specialist company then it may be more expensive that collecting it yourself.
Makes extra use of original data you already have by processing for a different purpose	There may be only a small part of the data needed so you have to extract what you want from a large data set.
Archiving ensures that all the data you have collected is available for uses you have not considered just yet.	You may not be able to obtain exactly the data you want.
