Averages & Basic Statistics
The mean is the equal-share or balance value determined by a total, while median, mode, and range describe different features of a data set.
What you'll learn
- Interpret the mean as an equal-share value that preserves the total.
- Use total = mean × count to combine groups and recover missing values.
- Distinguish mean, median, mode, and range.
- Weight subgroup means by their group sizes.
