Mean vs Median vs Mode
Mean (average): sum all values, divide by count. Median: the middle value when sorted — if even count, average the two middle values. Mode: the value that appears most often — a dataset can have multiple modes or none.
Standard Deviation
Standard deviation measures how spread out the values are from the mean. A low standard deviation means values are clustered near the mean; a high standard deviation means they are spread out widely.
