Study Notes
Arithmetic Mean
- The arithmetic mean, often called the average, is a measure of central tendency.
- It's calculated by summing all the values in a dataset and dividing the sum by the number of values.
- The formula for the arithmetic mean is:
-
x̄ = (Σx)/n -
x̄represents the arithmetic mean -
Σxrepresents the sum of the values -
nrepresents the number of values
-
- The arithmetic mean provides a single value that summarizes the typical value in a dataset.
- It's commonly used because it's easy to calculate and understand.
- However, the arithmetic mean can be heavily influenced by outliers or skewed distributions.
- It's best for datasets that are relatively symmetrical without extreme values.
