Frequently Asked Questions
Mean is the mathematical average of all numbers (sum divided by count). Median is the exact middle value when the numbers are sorted in order. The median is often a better indicator of "typical" values when a dataset has extreme outliers (like income).
If all numbers appear exactly once, the set has "No Mode". If multiple numbers share the highest frequency, the set is considered "bimodal" or "multimodal", and all those numbers are the modes.
The range describes the spread of your data. It is calculated by finding the highest number (maximum) and subtracting the lowest number (minimum).
