Given in the question that, the number of automobiles per family. We have to decide which type of grouping is probably the best

Single-value grouping:

To group quantitative data, employ classes in which each class represents a single possible value; these classes are known as single-value classes, and single-value grouping is the way of grouping quantitative data.

Limit grouping:

To group quantitative data, class limits are used. Each class is made up of a number of different values. The lower limit of the class is the smallest value that can be entered, and the upper limit of the class is the highest value that may be entered. Limit grouping is a method of categorising quantitative data.

Cut-point grouping:

To group, quantitative data utilise class cut-points, which consist of a range of values for each class. The lower cut-points of a class are the smallest values that could fit in the class, while the upper cut-points of the class are the smallest values that could fit in the next higher class.

Cut-point grouping is a way of categorising quantitative data using cut-points.

Consider the following scenario.

Per family, the number of autos.

The number of cars can be any number, and the class can be anything from $0,1,2,3$, and so on. However, this figure may not be excessive.
