A group of adults is surveyed on the number of hours of sleep which they had the night before.

One adult says that they slept for five-and-a-half hours. This value doesn't fit neatly into any class interval because

• It is not possible to sleep for five-and-a-half hours

• "Hours slept" is a continuous variable, but the class intervals are set up for discrete data

• "Hours slept" is a categorical variable, but the class intervals are set up for numerical data

• "Hours slept" is a discrete variable, but the class intervals are set up for continuous data
