Goal: To standardize data using linear transformations to work with a common scale to make comparisons. 1. Linear Transformations. Recall the data set X : 1,2,3,4,5. Consider V = -2X. Note that 0 = -6 = -2 x and s? = (-2) 2.5. Find v, s., IQR., and range,. What are Q1 and Qa? : -2, 41 - 6, 8,-10 V= -6 , 81= 182 = 2-2.5., 1QR=-4-(-8), ranger=-2-(-10) ort : =-2x =125x =4 =8 - 101 - B,-6,-4-2 = 1-21- 1QRX = 1- 21 - range ( includes aco )
