Math Problem Statement
To calculate the SUS score, first sum the score contribution from each item. each item's score contribution will range from 0 to 4. for items 1, 3, 5, 7, and 9 the score contribution is the scale position minus 1. for items 2, 4, 6, 8 and 10, the contribution is 5 minus the scale position. multiply the sum of the scores by 2.5 to obtain the overall value of SUS.
