Analyzing the Data
Multiple chart types are available in the Constant Sum question, including column, pie, doughnut, bar, and line charts. A table is also available that shows the average score and percentage of responses for each row question.
To view detailed values for each row question, click Details located after each answer choice. You can also click Scale Distribution to see a distribution of these values. The values can be divided into 2-10 parts for better granularity.
The average score and responses percentage for each row question are calculated by the following formulas:
Average Score for each row question = (Sum of all values) / (Number of responses)
Responses Percentage for each row question = Average Score for each row question / Total assignable value
For example, the average score for Offline shopping is 34.17, it is calculated:
(20 + 30 + 40 + 12 + 43 + 60) / 6 = 34.17
The responses percentage for Offline shopping is 34.17%, it is calculated:
34.17 / 100 = 34.17%
