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 29, it is calculated:

(20 + 30 + 40 + 12 + 43 ) / 5 = 29

The responses percentage for Offline shopping is 29%, it is calculated: 

29 / 100 = 29%
