Study Notes

Organizing Data

Raw data is transformed into a frequency distribution using descriptive statistical methods.
A frequency distribution is a table form that organizes raw data into classes and frequencies.

Frequency Distribution

A class is a quantitative or qualitative aspect in which data are distributed.
The frequency of a class is the number of data values placed in that class.
The distribution of a variable refers to the set of all possible values of a variable and their associated frequencies or probabilities.

Types of Distributions

Heterogeneous distribution: a distribution of values where all outcomes are nearly equally likely.
Homogeneous distribution: a distribution of values that cluster around one or more values, while other values occur with very low frequencies or probabilities.

Frequency Distribution Types

Categorical frequency distribution: used for nominal-level or ordinal-level data.
