By default, for any question, the first answer option is given a score of 1, the second answer option a score of 2, etc. The formula used to calculate a mean is as follows. Xn = number of responses (such as 3 responses for the first answer option, 5 responses for the second answer option, etc.) Wn = score (default of 1 for the first answer option, 2 for the second answer option, etc.) n = total number of responses obtained for the question MEAN = [(X1 * W1)+ (X2 * W2) + (X3* W3) +… (Xn * Wn)]/n

To adjust scores, you’ll want to use the Custom/Inverse Scale.
The weighted average scoring model applies a “weight” to the matrix questions based on responses to the first item in a side-by-side matrix. Generally the first item measures attributes like “Importance,” “Need,” or “Expectation”. In such cases, the values of the subsequent dimensions (“Satisfaction” , “Use” or “Delivery” etc.) can weighed based on corresponding scores from the first attribute.
For each Side-By-Side matrix question, there is an “Anchor” dimension. This is the first dimension listed, and we call it the anchor. In most cases, this is the “Importance” or “Expectation” dimension. NOTE – THIS HAS TO BE THE FIRST DIMENSION YOU MEASURE. QuestionPro automatically assumes that the first dimension is the anchor. All subsequent calculations are based on the anchor. The weight for each item in the anchor is calculated by this formula: Weight(n) = Anchor Score(n) / Sum of [Anchor Score]
Adjusted Score(n) = Weight(n) * Score(n)
