This tool helps you calculate the average rating based on scores you input.

## How to use the Rating Calculator

To use the rating calculator, please enter your ratings for each category in the provided input fields. Each rating should be a number between 1 and 5, where 1 is the lowest rating and 5 is the highest. Once you have entered all the ratings, click the “Calculate” button. The calculator will then compute and display the average rating in the “Result” field.

### How it calculates the results

The calculator takes the ratings you input and sums them up. It then divides the sum by the number of rating inputs (5 in this case). The final result is rounded to two decimal places for clarity and displayed in the “Result” field.

### Limitations

This rating calculator assumes that all input ratings are given equal importance. If the ratings should not be equally weighted, this calculator may not be appropriate. Additionally, the ratings must be between 1 and 5; values outside these bounds may lead to incorrect results.

## Use Cases for This Calculator

### Use Case 1: Calculate Average Rating

Calculate the average rating of a product or service by entering individual ratings given by customers. The calculator will sum up all the ratings and divide by the number of ratings to provide the average score, giving you a quick overview of overall sentiment.

### Use Case 2: Weighted Rating Calculation

Determine the weighted average rating considering the importance of each rating. Assign weights to individual ratings based on relevance or significance and input them along with the ratings. The calculator will calculate the weighted average, reflecting the impact of each rating appropriately.

### Use Case 3: Adding New Rating to Existing Average

Add a new rating to an existing set of ratings and recalculate the average rating. Enter the new rating, and the calculator will incorporate it into the current average calculation, giving you an updated overall rating instantly.

### Use Case 4: Calculating Percentile Rating

Convert ratings into percentile scores to understand the relative position of a rating within a distribution. Input the rating and total ratings received to calculate the percentile rating, providing a clearer picture of how a particular rating compares to others.

### Use Case 5: Finding Maximum and Minimum Ratings

Determine the highest and lowest ratings from a list of ratings to identify extremes. Enter all the ratings, and the calculator will display the maximum and minimum values, helping you understand the range of ratings received.

### Use Case 6: Adjusting Ratings for Normalization

Normalize ratings to a specific scale for consistency and comparability. Input the original rating scale and value, along with the desired scale range, and the calculator will adjust the rating accordingly, ensuring uniformity across different rating systems.

### Use Case 7: Calculating Rating Deviation

Assess the deviation or variation of ratings from the average to gauge the consensus among raters. Input all the ratings, and the calculator will compute the standard deviation, highlighting how dispersed the ratings are from the average, indicating consensus or divergence.

### Use Case 8: Weighted Sum Rating Calculation

Calculate the weighted sum of ratings by assigning different values to each rating. Enter the ratings and their corresponding weights, and the calculator will sum up the weighted ratings, providing a comprehensive view of the overall score considering varying importance.

### Use Case 9: Comparing Two Sets of Ratings

Compare two sets of ratings for different products or services to identify performance differentials. Input the ratings from each set, and the calculator will analyze and display the comparative results, aiding in decision-making and performance evaluation.

### Use Case 10: Calculating Rating Improvement Percentage

Determine the percentage increase or decrease in ratings over time to evaluate performance trends. Input the initial and final ratings to calculate the improvement percentage, offering insights into the progression or regression of rating scores.
