1. What is Average Rating Out of 5?

The Average Rating Out of 5 is a standardized way to compare ratings that were originally given on different scales. It converts ratings from any maximum value to a consistent 5-point scale.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \sum(\text{Ratings}) \) — Sum of all individual ratings
• \( n \) — Number of ratings
• \( \text{max} \) — Maximum possible rating in original scale

Explanation: The equation first calculates the average in the original scale, then converts it to a 5-point scale by multiplying by the ratio of 5 to the maximum possible rating.

3. Importance of Rating Calculation

Details: Standardizing ratings to a 5-point scale allows for fair comparison between products or services that were rated on different scales (e.g., comparing a 10-point scale with a 100-point scale).

4. Using the Calculator

Tips: Enter all individual ratings separated by commas, and specify the maximum possible rating in the original scale. For example, for three ratings of 8, 9, and 7 out of 10, enter "8,9,7" and set maximum to 10.

5. Frequently Asked Questions (FAQ)

Q1: Why convert to a 5-point scale?
A: The 5-point scale is widely recognized and easier to interpret than scales with more granularity.

Q2: Can I use this for percentage ratings?
A: Yes, for percentages the maximum rating would be 100.

Q3: What if my ratings are already out of 5?
A: Set the maximum rating to 5 and the calculator will just compute the average.

Q4: How should I round the result?
A: The calculator rounds to 2 decimal places, but you may want to round to nearest half or whole number depending on your needs.

Q5: Can I use this for star ratings?
A: Yes, this is particularly useful for comparing star ratings from different platforms that might use different maximum star values.
