    The following table gives data for 5 students in a statistics course
    Name Age Class-standing Year-entered
    Bill 19 S 2012
    Dawn 27 F 2013
    Sharmon 23 J 2010
    Joe 31 F 2011
    Connie 21 F 2014
    The data set consists of ordered quadruples (name, age, class-standing, year-entered). Describe each variable as nominal, ordinal, interval or ratio.

    I agree with Oruada
    Nominals = the Names: Bill, Dawn, Sharmon, Joe and Connie
    Ordinal = the Letters: S, F, J, F, & F
    Interval = 2012, 2013, 2010, 2011, & 2014
    Ratio = the Ages: 19, 27, 23, 31, & 21

    I agree with both Parul and Oruada but wouldn’t the ages be ordinal as well

    Ariel, no the ages are consdier ratio because you can do a ration with them. For example we can say that one person is doubled the age of another person. I hope you understand.
