For items 1,3,5,7, and 9 the contribution of the score is the position scale minus 1.For items 2,4,6,8 and 10 the contribution is 5 minus the position scale.Multiply the total score by 2.5 to get the overall SUS score [4].
How to calculate = ((1 1) + (5 2) + (3 1) + (5 4) + (5 1) + (5 6) + (7 1) + (5 8) + (9 1) + (5 10)) 2.5).The rules in calculating the score apply to 1 respondent.For further calculations, the SUS score of each respondent is sought for the average score by adding up all scores and dividing by the total number of respondents.Here's the formula for calculating the average of the overall SUS scores: The description of the example of the calculation of the questionnaire data from the table of respondent 1 using the rules of the SUS calculation method is as follows: 1) In Question number 1 the respondent chooses a scale of 5, then the score for question number 1 is 4 (Question number 1 has a positive tone for this question score obtained from the position of the scale minus 1) 2) In question number 2, the respondent chooses a scale of 1, then the score for question number 2 is 4 (question number 2 is negative.The score for this question is obtained from 5 minus the position on the scale) 3) In question number 3, the respondent chooses a scale of 5, then the score for question number 3 is 4 (question number 3 has a positive tone for this question score obtained from the position of the scale minus 1) 4) In Question number 4 the respondent chose a scale of 1, then the score for question number 4 is 4 (question number 4 is negative.The score for this question is obtained from 5 minus the position on the scale) 5) In question number 5 the respondent chose a scale of 5, then the score for question number 5 is 4 (question number 3 has a positive tone for this question score obtained from the position of the scale minus 1) 6) In question number 6, the respondent chooses a scale of 2, then the score for question number 6 is 3 (question number 5 is negative.The score for this question is obtained from 5 minus the position on the scale) 7) In question number 7 the respondent chooses a scale of 5, then the score for question number 7 is 4 (question number 7 has a positive tone for this question score obtained from the position of the scale minus 1) 8) In Question number 8 the respondent chooses a scale of 1, then the score for question number 8 is 4 (question number 5 is negative.The score for this question is obtained from 5 minus the position on the scale) 9) In question number 9 the respondent chose a scale of 4, then the score for question number 9 is 3 (question number 9 is positive for this question score obtained from the position of the scale minus 1) 10) In Question number 10 the respondent chooses a scale of 1, then the score for question number 10 is 4 (question number 5 is negative.The score for this question is obtained from 5 minus the position on the scale) [5].
