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.
