Chapter 2: Section 2.2 - Frequency Distributions: Constructing a Frequency Distribution Table

What is the formula for determining the Percentage For A Class in a Relative Frequency Distribution Table?

((Frequency For A Class) / (Sum of All Frequencies)) x 100

After deciding the number of classes desired for the table, the Class Width is determined as...

(Minimum Data Value - Maximum Data Value) / (Number of Classes)

Class Width

The difference between two consecutive lower class limits in a frequency distribution table

Upper Class Limits

The largest numbers that can belong to the different classes

Class Boundaries

The numbers used to separate the classes, but without the gaps created by class limits

Lower Class Limits

The smallest numbers that can belong to the different classes

What is the formula for determining the values of a Cumulative Frequency Distribution Table?

...

________ ________ are the numbers used to separate the classes, but without the gaps created by class limits.

Class Boundaries are the numbers used to separate the classes, but without the gaps creates by class limits.

________ ________ are the values in the middle of the classes.

Class Midpoints are the values in the middle of the classes.

________ ________ is the difference between two consecutive lower class limits in a frequency distribution table.

Class Width is the difference between two consecutive lower class limits in a frequency distribution table.

T or F: Two consecutive lower class limits are different between one consecutive class boundary.

False - Two consecutive lower class limits are the same as the difference between two consecutive class boundaries.

________ ________ ________ are the smallest numbers that can belong to the different classes.

Lower Class Limits are the smallest numbers that can belong to the different classes.

Class Midpoints

The values in the middle of the classes

T or F: After determining the Class Width, round up to obtain a convenient value.

True

________ ________ ________ are the largest numbers that can belong to the different classes.

Upper Class Limits are the largest numbers that can belong to the different classes.
