Weighted and Unweighted Average SERVQUAL Scores?
If the unweighted average SERVQUAL score is 1.312, and the average weighted score is 30.606 what does that mean? I'm using the average discrepancy between a customer's expectations and the customer's perceptions for 5 SERVQUAL dimensions, likerttype scale were used for ranking the statements anchored 1 to 7 with “strongly disagree” and “strongly agree”, using 22 questions in total for 100 surveyed users. Please help?

The Unweighted Average SERVQUAL Score
The "Unweighted Average SERVQUAL Score" is simply the mean (=average) of the mean scores in the 5 dimensions.
For example, let's suppose you obtained following GAP scores (Perception score  Expectation score) per dimension:
Dimension 1. Tangibles  mean for this dimension (PE): 0,65
Dimension 2. Reliability  mean for this dimension (PE): 1,10
Dimension 3. Responsiveness  mean for this dimension (PE): 0,83
Dimension 4. Assurance  mean for this dimension (PE): 0,70
Dimension 5. Empathy  mean for this dimension (PE): 1,01
This would mean your Unweighted Average SERVQUAL Score = (0,65 + 1,10 + 0,83 + 0,70 + 1,01) : 5 = 4,29 : 5 = 0,86.
This means the customers expected your service level to be an average of 0,86 per dimension higher than what they actually got from your company.
By the way, because the perceived GAP in dimension 2 is the biggest, reliability could be the place to start improving your service quality.
