First, the table has approximately 10 (options, class
intervals, or interval widths)
The width of each interval is a relatively (wide, simple, or
complex) number.
The bottom score in each class interval is a (reflection,
multiple, or factor) of the width.
In which interval would a score of 29.6 fall? (20-29, there is
no interval for this number, or 30-39)
In which interval would a score of 19.4 fall? (There is no
interval for this number, 10-19, or 20-29).
