Statistics Measures and Median Calculation

Vocabulary flashcards covering fundamental statistical concepts, formulas for mean, and steps for calculating median.

Mean ($\bar{x}$)

The arithmetic average of a set of observations, given by the formula $\bar{x} = \frac{\sum_{i=1}^N x_i}{N}$

A.O

Ascending Order, the arrangement of data from lowest to highest value as the first step in finding the median

L.C.F

Less than Cumulative Frequency, prepared during data processing to assist in determining the median

$$\frac{N}{2}$$

The middle value point calculated by dividing the total number of observations ($N$) by $2$ to locate the median

Median Class Selection

The rule of finding the class or value where the cumulative frequency satisfies $CF \ge \frac{N}{2}$
