Example 28.2: Computing Chi-square Tests for One-Way Frequency Tables This example examines whether the children's hair color (from Example 28.1) has a specified multinomial distribution for the two ...

Example The table below shows the lengths of 40 babies at birth. To calculate the cumulative frequencies, add the frequencies together.

A grouped frequency table is a way of presenting data in groups called classes close classA group created to contain a set of data. For example, the class 10 < 𝒙 < 20 contains values of 𝒙 ...

The frequency table lists the variable values (hair color) in the order that they appear in the data set. The last column lists the hypothesized percentages for the chi-square test.
