Frequently Asked Questions
What is standard deviation?
Standard deviation measures how spread out numbers are from the mean. A low value means data points are close to the mean; a high value means they are spread out.
What are quartiles?
Quartiles divide a sorted dataset into four equal parts. Q1 is the 25th percentile, Q2 is the median (50th), and Q3 is the 75th percentile. IQR = Q3 - Q1.
