Frequently Asked Questions
Quartiles divide a dataset into four equal parts. Q1 is the median of the lower half, Q2 is the overall median, and Q3 is the median of the upper half.
When the number of data points is even, the median is the average of the two middle numbers after sorting.
IQR (Interquartile Range) is the difference between Q3 and Q1. It measures the spread of the middle 50% of the data.
