Step by step
The formula
mean, median (middle), mode (most frequent)
Mean, median and mode are three different answers to “what is typical here?”. The mean uses every value so outliers pull it; the median only cares about position so it resists them; the mode reports the most common value. Comparing all three tells you how skewed your data is.
