All of these options are guidelines for constructing a frequency distribution. An open-end class means that the highest or lowest value in a dataset has no upper or lower limit, respectively. While it may be necessary to use open-end classes in some cases, it is generally preferred to use closed-end classes with defined upper and lower limits. The classes must also be mutually exclusive, meaning that each value in the dataset can only fall into one class, and they must be exhaustive, ensuring that every value in the range of the variable is included in a class. Equal-width classes allow for an even distribution of data within each class, while choosing round numbers for class widths simplifies the presentation and interpretation of data.
