Section 3.4 & 3.5 David Holmes STAT 250 Feb 22 Comparing Measures and Distributions  Appropriate Measures  Using Measures to Determine Shape  Using Measures to Compare Distributions Appropriate Measures When dealing with numerical data, one describes the distribution using the characteristics: shape, center, and spread. • What measures for center and spread is best suited for the data Mean or median Standard deviation or IQR • Depends on the shape of the distribution! The shape of the distribution will determine which measures are best for communicating typical values and variability. Example 3.14: S
