The average rating is a statistical measure that represents the central value of a set of ratings. It is calculated by summing all individual ratings and dividing by the total number of ratings.
The calculator uses the average rating formula:
Where:
Explanation: The formula calculates the arithmetic mean of all given ratings, providing a single value that represents the overall rating.
Details: Average rating is widely used in product reviews, customer feedback systems, academic grading, and performance evaluations to provide a quick overview of overall satisfaction or quality.
Tips: Enter ratings as comma-separated values (e.g., "4,5,3,4,5"). The calculator will ignore any non-numeric values and calculate the average of valid numbers.
Q1: What is the range of valid ratings?
A: Ratings can be any numeric values. Common rating scales include 1-5 stars, 1-10 points, or percentage scores (0-100).
Q2: How does the calculator handle decimal ratings?
A: Decimal ratings are fully supported and will be included in the calculation with appropriate precision.
Q3: What if I enter non-numeric values?
A: Non-numeric values will be automatically filtered out and only valid numbers will be used in the calculation.
Q4: Can I calculate weighted average with this calculator?
A: No, this calculator computes simple arithmetic mean. For weighted averages, each rating would need to be multiplied by its weight before averaging.
Q5: How many ratings can I enter at once?
A: There is no strict limit, but extremely large numbers of ratings may affect performance. For practical purposes, hundreds of ratings can be processed.
