Installation and Setup of a Hardware/Software Product: Quantitative Test Results
These quantitative results were compiled by measuring the time required to complete the test tasks, and by counting the number times a user required major assistance. These results served as benchmarks for the product in future iterations of the tests.

Quantitative Results: Time and Difficulty
Key to the tables below:
# of Tests The number of times this task or subtask was attempted by a user.
Average Time The average time required to complete a task or sub-task for all of the users who attempted it.
Average # of Assists For all tests, the average number of times users reached a dead end and could not proceed without calling a help line or being assisted.
# of Assists For all tests, the total number of times users reached a dead end and could not proceed without calling a help line or being assisted.
