Directions: Classify the following random variables as discrete or continuous. In discrete data, the number of possible values is countable, while continuous data is measurable and can take on infinite values. Let's say for a moment that instead of height, you want to measure how many siblings a person has and see if people with more siblings have higher IQs. The difference between discrete and continuous data can be drawn clearly on the following grounds: Discrete data is the type of data that has clear spaces between values. Decide whether each of the following is a discrete or continuous random variable ... Can be decimal numbers, for example, 96.7 ºF. Distance, set of real numbers and mass are some common examples of continuous data. A continuous variable is a variable whose value is obtained by measuring. a person's height is continuous because it is measurable. Discrete. In addition, determine the measurement scale. If variable is categorical, determine if it is ordinal based on whether or not the levels have a natural ordering.
