Unpacked Content

Knowledge

Students know:

Characteristics of a two-way frequency table.
Methods for converting frequency tables to relative frequency tables.
That the sum of the frequencies in a row or a column gives the marginal frequency.
Techniques for finding conditional relative frequency.
Techniques for finding the joint frequency in tables.
Use mathematical vocabulary to describe associations and trends in data.

Skills

Students are able to:

Accurately construct frequency tables.
Accurately construct relative frequency tables.
Accurately find the joint, marginal, and conditional relative frequencies.
Recognize and explain possible associations and trends in the data.

Understanding

Students understand that:

Two-way frequency tables may be used to represent categorical data.
Relative frequency tables show the ratios of the categorical data in terms of joint, marginal, and conditional relative frequencies.
Two-way frequency or relative frequency tables may be used to aid in recognizing associations and trends in the data.
