Frequently Asked Questions
What's the difference between mean, median, and mode?
Mean = sum/count. Median = middle value. Mode = most frequent. They're similar for symmetric data but differ for skewed data.
When to use median instead of mean?
When data has outliers. Median household income is more representative because billionaires distort the mean.
How do you calculate average?
Add all numbers, divide by count. Average of 4, 8, 15, 16, 23, 42 = 108 ÷ 6 = 18.
What if there are two modes?
Data with two modes is bimodal. No repeats = no mode.
What does range tell you?
Range = max − min. Shows spread but is sensitive to outliers. Standard deviation is better for measuring spread.
