Quantification of task related activity by statistical and analytical methods

摘要

Behaviour of expert and novice database users solving the same task was recorded. Several successful strategies were identified. Since there are more users than strategies, some users applied the same strategy. The aim was to develop methods grouping users with common strategy. Following three approaches (correlation, intersection, and exclusion), a metric among task solving behavioral sequences was defined. Measured data was organised in matrix systems relating all users. Statistical and analytical interpretation of matrices showed distinct groups. A common denominator for a group can indicate a strategy.
