Discrete data can only take on certain specific values, while continuous data can take on any value within a range. For example, the number of people in a room is discrete data, because it can only take on whole number values. The weight of a person, on the other hand, is continuous data, because it can take on any value within a range of possible weights.
The weight of a motorcycle can take on any value within a range of possible weights. Therefore, the weight of motorcycles is continuous data.
