Men who are somewhere between 63 and 75 inches tall would be considered of a fairly normal height. Men shorter than 63" or taller than 75" would be considered unusual (assuming our sample data represents the actual population). You could use a z score to look up exactly what percentage of men are shorter than (or taller than) a particular height.

Think of something in your work or personal life that you measure regularly (No actual calculation of the mean, standard deviation or z scores is necessary). What value is "average"? What values would you consider to be unusually high or unusually low? If a value were unusually high or lowhow would it change your response to the measurement?
