Theory & Formula
Central Tendency
Central tendency measures describe the center or typical value of a dataset.
Mean (Average)
The arithmetic average of all values
\(\bar{x} = \frac{1}{n} \sum_{i=1}^{n} x_i = \frac{x_1 + x_2 + ... + x_n}{n}\)
Median
The middle value when data is sorted
For odd number of values: the middle value: \(\text{Median} = x_{(n+1)/2}\)
For even number of values: average of two middle values: \(\text{Median} = \frac{x_{n/2} + x_{n/2+1}}{2}\)
Mode
The most frequently occurring value(s)
Väärtuspiirkond
The difference between the maximum and minimum values
\(\text{Range} = x_{\max} - x_{\min}\)
