h1 dir="ltr">This guide will walk you through standard study level metrics on MUiQ.

MUiQ comes with several built-in standard question templates for post-study metrics. 

These should be added to the Post-Study tab or the Post-Condition tab if you want to compare the metrics across competitors or conditions.

These metrics include the NPS, SUPR-Q®, SUS, and UX-Lite™. Please refer to the following pages for more details on each of these metrics.

MUiQ includes built-in real-time analysis for each of these metrics in the study results dashboards.

SUS System Usability Scale

• The SUS is a 10-item questionnaire with five response options regarding a mix of positive (+) and negative (‒) items.
• Created in 1986 it is the most used questionnaire for measuring perceptions of usability.
• SUS scores range from 0 – 100 (higher is better), but these are not percentages.
• The SUS scores can be converted into percentile ranks and assigned letter grades to assess how good a score is. 

UX-Lite

• Based on the popular UMUX-Lite (Usability Metric for User Experience)
• The UX-Lite is a 2-item questionnaire with five response options.
• UX-Lite scores range from 0 – 100 (higher is better), but these are not percentages. 
• Like SUS scores, UX-Lite scores can be converted to percentile ranks and assigned letter grades.

NPS - Net Promoter Scores

• The NPS (Net Promoter Score) is a popular measure of customer loyalty. It’s derived by asking a single question to a customer.
• The scores are expressed as raw percentages ranging from -100% to +100%. 
• NPS = % Promoters – % Detractors

SUPR-Q

• The SUPR-Q (Standardized User Experience Percentile Rank Questionnaire) is a psychometrically valid and reliable 8-item questionnaire that measures the critical aspects of the website user-experience.
• The SUPR-Q provides relative rankings expressed as percentiles, comparing the UX score to over 200 websites.
