1 +**Interpretation for user evaluation **
2 +
3 +If a respondent had a minimum total score of 60% (15 out of 25 for the matrix question) or more, he or she was considered to be satisfied with the application.
4 +
5 +**Scoring SUS**
6 +
7 +* For odd items: subtract one from the user response.
8 +* For even-numbered items: subtract the user responses from 5
9 +* This scales all values from 0 to 4 (with four being the most positive response).
10 +* Add up the converted responses for each user and multiply that total by 2.5. This converts the range of possible values from 0 to 100 instead of from 0 to 40.
11 +
12 +**Interpreting Scores for SUS [[*>>https://measuringu.com/sus/]]**
13 +
14 +Interpreting scoring can be complex. The participant’s scores for each question are converted to a new number, added together and then multiplied by 2.5 to convert the original scores of 0-40 to 0-100.  Though the scores are 0-100, these are not percentages and should be considered only in terms of their percentile ranking.
15 +
16 +Based on research, a SUS score above a 68 would be considered above average and anything below 68 is below average, however, the best way to interpret your results involves “normalizing” the scores to produce a percentile ranking.
