This example above is an example of many different types of research we are looking at. To start of with is, this is a primary research conducted by the NRS, when other companies and individuals look at this research, it becomes secondary research.
If one of the newspaper companies wanted to see their competition sales figures, they can use this information to do their market research.
It is also an example of audience research because they have broken the audience down to different classifications for example, they have classified age (15-44).
Finally, it is an example of quantative research because it is all numbers based and anyone who looks at the information would be able to analyse and study this information for their own purposes.
