# 2263594- How is the star rating for a course calculated?

### Symptom

• In order to calculate a course's star rating, the LMS starts by determining the mean value based on a frequency table. An Example of this calcuation is provided within the resolution.

### Environment

• SuccessFactors Learning Management System

### Resolution

• EXAMPLE - Course Rating
• ***** (80)
• **** (261)
• *** (309)
• ** (315)
• * (316)

• Mean = ((316 x 1) + (315 x 2) + (309 x 3) + (261 x 4) + (80 x 5)) / total stars (1,281) = 2.581
• Now that the mean has been calculated, it will be rounded to the nearest quarter using the method below:
• Mean x 4 = 10.326, a floor is then applied which forces an integer value no greater than the value given. In this case 10.326 is provided, the highest integer value possible in this case is 10. Now that an integer is provided, it is divided by 4. As a result the course rating is below:
• 10 / 4 = 2.5 stars
