How is the average rating calculated from the review counts?

The average rating uses a weighted average formula: (5×N₅ + 4×N₄ + 3×N₃ + 2×N₂ + 1×N₁) ÷ Total Reviews, where N values represent the number of reviews at each star level from 1 to 5.

Can I use sample data or preset scenarios with this calculator?

Yes, the tool includes Quick Presets that let you load sample data for different product quality scenarios, and results update instantly as you modify input values.

What visual outputs does the calculator provide besides the average rating?

The calculator provides percentage breakdown across all star levels and interactive bar charts that display the rating distribution clearly.

Is there a way to reset the inputs if I make an error or want to start over?

Yes, a Clear All button is available to reset all input fields, and users can also modify individual values to see real-time updates to the results.
