The Percentile Calculator analyses where values fall within a dataset. Find the percentile rank of a specific value, determine the value at any given percentile, compute quartiles (Q1, Q2, Q3) with IQR and outlier detection, or calculate all nine deciles with a visual box plot.
Enter your data as comma-separated values and choose your analysis mode. The calculator sorts data, applies linear interpolation, and displays results with step-by-step workings and an SVG box plot.
