Hey there. My name is Zach Bobbitt. I have a Masters of Science degree in Applied Statistics and I’ve worked on machine learning algorithms for professional businesses in both healthcare and retail. I’m passionate about statistics, machine learning, and data visualization and I created Statology to be a resource for both students and teachers alike. My goal with this site is to help you learn statistics through using simple terms, plenty of real-world examples, and helpful illustrations.
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”
