The Other/Unknown category is large compared to some of the other categories (Native American, 0.6%, Pacific Islander 1.0%). Click to reveal The data are discrete because the data can take on any value in an interval. Therefore this is discrete data. A random number generator is used to select a student from the alphabetical listing of all undergraduate students in the Fall semester. According to a report, today, at least 2.5 quintillion bytes of data are produced per day. Age is discrete data because we could be infinitely precise and use an infinite number of decimal places, rendering age continuous as a result. In statistics, a sampling bias is created when a sample is collected from a population and some members of the population are not as likely to be chosen as others (remember, each member of the population should have an equally likely chance of being chosen). The data are discrete because the data can take on any value in an interval. Quantitative data may be either discrete or continuous.
