8 – Available Data

Why Should I Care?

Many – if not most – researchers are producing reports based on data that was collected by someone else. This is convenient because it saves time and money. But it is also tricky because there may be gaps or errors in the data that the end-use researcher is not aware of.

Usefulness

The point of this is to use data that already exists. Especially easy if you download the data set from the internet. Much of the data is collected for one purpose, but researchers can cross datasets together, and analyze all sorts of information in ways that were not necessarily meant to be.

Sampling

Collection is already done. The researcher has to live with the sampling technique, and its flaws, that the previous researcher has chosen and used.

Operationalization can be difficult. Some phenomena are hard to measure, but can be observed indirectly. Careful in the interpretation. Ex: innovation measured in patents. Lots of innovations are kept secret, but we don’t know how many since they are secret.

Instruments

No instrument. Data is previously collected. Usually survey.

 

Scientific Power

Exploratory: can be. If you don’t know what you are looking for, you can draw graphs for fun to look for stories.

Descriptive: most likely. You will associate variables, using tables and graphs.

Explanatory: can be done. Tread lightly. The variables that don’t correlate can be eliminated. Those that do correlate will be kept. However, be sure to establish temporal order first, that will determine the cause-effect relationship.
