Describing Data Two ways to describe data: Graphically Numerically

Dotplot Histogram Boxplot Describing Data Graphically

Describing Data Numerically Measures of Center – mean, median Measures of Spread – range, interquartile range, standard deviation

Measures of Center What is the typical value?

Measures of Spread Range Interquartile Range (IQR) Standard Deviation How much do values typically vary from the center?
