Ages of Householders. The ages of householders, given as a whole number

In this case, decide which type of grouping (single-value, limit, or cutpoint) is probably the best.

Given in the question that the ages of Householders. It is given as a whole number

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

Consider the following scenario.

The ages of the residents, expressed as a whole number.

The age of the household is a whole number, and to categorise the data, there are data ranging from $1$to $100$, with some data exceeding $100$.
