Which one of the following is an example of continuous data? Circle your answer. Is it number of paint buckets, number of walls painted, type of paint used, or time taken to paint walls?

Before starting this question, we need to understand the difference between discrete and continuous data. Discrete data can only take certain values, whereas continuous data can take any value. Examples of discrete data are shoe size, number of goals scored, and age. Examples of continuous data are height and weight.

In this question, we’re looking for the answer that is an example of continuous data. The first option, number of paint buckets, is an example of discrete data. We could have one, two, three, and so on number of paint buckets. They are discrete integer values. Likewise, the number of walls painted is also discrete. This will again be an integer whole number value.

The type of paint used is neither discrete nor continuous. It is categorical. This is because the type of paint fits into a category. It could be the type of color or the actual type of paint, for example, matte and gloss.

The final option, time taken to paint the walls, is an example of continuous data. This is the correct answer. This is because time is a continuous variable and doesn’t have to take certain values. Out of the four options, the example of continuous data is time taken to paint walls.
