Question: Recognize the false statement(s). I. The numbers used to separate the classes, so that there are no gaps in the frequency distribution are called class limits. II. Class width for a class is found by subtracting the lower class limit from the upper class limit. III. Class midpoint is obtained by adding the lower and upper boundaries and dividing by 2. IV. The class limits should have the same decimal place value as the data, but the class boundaries should have one additional place value.
A ) II only B ) I and II C ) III and IV D ) I only
Steps to derive
1 The numbers used to separate the classes so that there are no gaps in the frequency distribution are called class boundaries (class boundaries are different from class limits).
2 The class width for a class is found by subtracting the lower class limit of one class from the lower class limit of the next class.
3 Class midpoint is obtained by adding the lower and upper boundaries and dividing by 2.
4 The class limits should have the same decimal place value as the data, but the class boundaries should have one additional place value.
