+* For odd items: subtract one from the user response. |
|

+* For even-numbered items: subtract the user responses from 5 |
|
100 |
+* This scales all values from 0 to 4 (with four being the most positive response). |
|
101 |
+* 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. |

+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. |

+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. |
