We also refer to this type of data as quantitative or numerical. QUESTION 2 The number of words that a typist can type per minute is an example of a ___________ 1. quantitative variable, discrete data. 2. qualitative variable, continuous data. 3. quantitative variable, continuous data. 4. qualitative variable, discrete data. 5. qualitative data variable. A discrete random variable is one that can take on a countable number of values. For example, if we define X as the number of heads observed in an experiment that flips a coin 10 times, then the values of X are 0, 1, 2, . . . , 10. The variable X can assume a total of 11 values. Obviously, we counted the number of values; hence, X is discrete.The number or words typed are whole numbers and are countable.
