  1. Your trimmed mean calculator reports 4 decimals of precision. However, are these rounded or truncated in the calculation process? Specifically, the same value 0f “7.0300” is reported for a trim range of 18.5% to 21.5% for the following dataset: “4.1, 3.8, 15.4, 12.3, 0.5, 4.5, 1.6, 13.7, 14.0, 11.9, 8.2, 4.0, 12.4, 0.3, 7.5, 0.1”
