After collecting my data I was wondering if it is the normal way to sum the total average importances of the alternative specific attributes that were used in the design to come up with their overall importance reflected to the other 'normal' attributes.
As you can see here below:
Average Importances Average Importances
Review Rating 11.48338
Review length - 1 star 14.37741

Review photo - 5 star 6.70581
Woonplaats reviewer 13.08315
For example, every review photo solely has low average importance, but when it is summed, the total importance rises to 15.28. Should that be the number to compare review photo with to the others, or is that incorrect?
I'm very curious about your answer.
Thank you in advance.
With kind regards,
