Computing Univariate Statistics Read Sections 6.6, 6.7, and 7.1 in The Little SAS Book and the procedure description handed out in class. You now know enough of SAS to do most of the important data manipulations. Now its time to begin using SAS to help with statistical computations.
Univariate statistics are numerical summaries of data that describe features of the distribution.
Suppose that a vending machine which dispenses hot beverages is supposed to dispense 6 ounces of a drink into a styrofoam cup. However, there is some variation in the amount dispensed, since the machine could be affected by such factors as external temperatures, liquid temperatures, and amount of liquid remaining. The variation in amounts dispensed was studied by purchasing 50 cups of coffee from the machine and carefully measuring the amount of coffee dispensed to the nearest 0.1 oz. Low p-values provide evidence that the population mean is not zero. Instead, SAS will phrase the p-value as a probability.
