This is how, within a full Frequency Table, you double check if its building is okay.

• You count the amount of frequencies.

• You add up the amount of frequencies.

• You average the amount of frequencies

• You add up the relative frequencies.

Within a Frequency Distribution Table, this variable refers to the number of groups.

• K - Class Width

• K - Number of Classes

• A - Class Width

• A - Number of Classes

Within a Frequency Distribution Table, this variable refers to apparent size of the class.

• K - Class Width

• K - Number of Classes

• A - Class Width
