Analysis and Evaluation RESOURCES I PRIMT I HELP

Analysis

By itself, test data is rarely useful to decision-makers. It must be turned into information. A vital step towards producing useful information from raw test data is analysis . Analysis involves more than just re­ stating the data.

Analysis is the process of using various mathematical or graphical techniques to structure and interpret test data in order to identify patterns, comparisons, or cause/ effect.

Analysis involves asking several questions:

• Is the data reasonable?

• Has enough data been gathered?
