FAQ
What is the difference between mean and median?
Mean is the arithmetic average. Median is the middle value when sorted. Median is more robust to outliers — it is why median household income is reported instead of mean.
When should I use standard deviation?
Standard deviation measures how spread out data is around the mean. Low SD = data clustered close to average. High SD = data spread widely.
