# Custom Scale - Analysis Based on Customized Scales and Weights | Reverse Scoring

## Calculating Mean and other statistical measures:

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

## How can I customize the mean?

There are two ways to customize the mean: selecting specific answer options to include and exclude from the mean calculation and customizing the scale used to calculate the mean.

• Go to:
• Login »  Surveys »  Reports »  Dashboard
• Click the gear icon next to the question for which you want to customize the mean.
• Click on Customize Mean Calculation
• uncheck the boxes next to the answer options you want to exclude from the mean calculation.
• Click on Update

The new mean can be found in the same location as before, under the answer options table.

## In my case, the first option does not necessarily represent 1 — in fact, the scores for my scales are reversed. How can I adjust the scores to be reflected in the mean?

To adjust scores, you’ll want to use the Custom/Inverse Scale. There are two ways to do this:

• Adjust the score from the Analytics tab
• Go to:
• Login »  Surveys »  Reports
• Click the gear icon next to the question for which you want to customize the mean.
• Click on Customize / Inverse Scaleoption
• Enter the weight you want to assign to each answer under the Scale Value column
• Turn the Customized Scaling option on
• Click on Save Scale Values
Customized Scale Weights need to be set up for each question individually.

## Can I apply net promoter or top/bottom custom scoring models to my question?

Yes. Any single-choice question can have net promoter or top/bottom scores assigned for calculation.

• Go to:
• Login »  Surveys »  Reports
• Click the gear icon next to the question for which you want to calculate net promoter or top/bottom score values.
• Click Custom Scoring Models.
• Select the type of Scoring Model you want to apply.
• Click on Save Scoring Model Values. Your scoring model will be calculated and shown in the report.
