A Matrix question is a closed-ended question that asks respondents to evaluate one or more row items using the same set of column choices.
A Rating Scale question, commonly known as a Likert Scale, is a variation of the Matrix question where you can assign weights to each answer choice. Rating Scales automatically calculate a weighted average for each answer choice in the Analyze Results section.
To add this question type:
Selecting this option does three things at once:
Assign a weight to each column, transforming the question into a Rating Scale or Likert Scale question with multiple rows.
Only allow respondents to select one choice per column. This asks respondents to compare the row choices to each other, similar to a Ranking question. This option will only appear if you only allow one response per row.
Before you send out your survey, preview your survey design to see what your survey will look like to respondents.
Depending on the respondent's screen size, large Matrix/Rating Scale questions with many columns may require respondents to scroll to the right to see all of the available column choices. Keeping Matrix/Rating Scale questions short and simple can improve completion rates.

If you require respondents to answer a specific number or range of rows, make sure you customize the error message to reflect the requirement, so respondents will know how to answer the question correctly.
If you selected Forced ranking (one response per column), respondents will only be able to apply each column choice to one row item. If a respondent tries to select the same column choice for another row, their previous selection will disappear.
Your results will be presented in a table with the questions or statements listed down the first column, and the answer choices listed across the first row.
If you enabled the Use Weights or Make this a single-row rating scale option when you created the question, you'll also see the average rating for each question or statement you asked respondents to evaluate.
If needed, you can change the weight of each answer choice in the Design section of the survey, even after the survey has collected responses.
The rating average is calculated as follows, where:
w = weight of answer choice
x = response count for answer choice
|(x1w1 + x2w2 + x3w3 ... xnwn) / Total|
If you chose to include an N/A column on your Rating Scale question, any N/A responses will not factor into the weighted average.
The Depth display option allows you to choose between the following options:
